Book excerpt: We propose a resonant electromagnetic detector to search for hidden-photon dark matter over an extensive range of masses. Hidden-photon dark matter can be described as a weakly coupled ?hidden electric field,? oscillating at a frequency fixed by the mass, and able to penetrate any shielding. At low frequencies (compared to the inverse size of the shielding), we find that the observable effect of the hidden photon inside any shielding is a real, oscillating magnetic field. We outline experimental setups designed to search for hidden-photon dark matter, using a tunable, resonant LC circuit designed to couple to this magnetic field. Our ?straw man? setups take into consideration resonator design, readout architecture and noise estimates. At high frequencies, there is an upper limit to the useful size of a single resonator set by 1/?. However, many resonators may be multiplexed within a hidden-photon coherence length to increase the sensitivity in this regime. Hidden-photon dark matter has an enormous range of possible frequencies, but current experiments search only over a few narrow pieces of that range. As a result, we find the potential sensitivity of our proposal is many orders of magnitude beyond current limits over an extensive range of frequencies, from 100 Hz up to 700 GHz and potentially higher.

Book excerpt: This dissertation introduces the Dark Matter (DM) Radio, a tunable, lumped-LC oscillator search for axion and hidden-photon dark matter between 1 peV and 1 ueV. The design of DM Radio is motivated from fundamental statements regarding impedance-matching to dark matter and optimal electromagnetic searches for axions and hidden photons subject to the Standard Quantum Limit (SQL) on phase-insensitive amplification. I describe the DM Radio Pathfinder, a prototype detector searching for hidden-photon dark matter between 400 peV and 40 neV. First data from the Pathfinder are presented. I propose the Radio-Frequency Quantum Upconverter (RQU), a device which enables DM Radio readout sensitivity beyond the SQL. The ultimate vision for DM Radio, a cubic-meter-volume resonant experiment operating at 10 mK with a 4 Tesla DC magnetic field and exploiting quantum metrology, is presented. This experiment will enable a probe of the QCD axion between 4 neV and 1 ueV.
Download or read book The Search for Ultralight Bosonic Dark Matter written by Derek F. Jackson Kimball and published by Springer Nature. This book was released on 2022-09-28 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: A host of astrophysical measurements suggest that most of the matter in the Universe is an invisible, nonluminous substance that physicists call “dark matter.” Understanding the nature of dark matter is one of the greatest challenges of modern physics and is of paramount importance to our theories of cosmology and particle physics. This text explores one of the leading hypotheses to explain dark matter: that it consists of ultralight bosons forming an oscillating field that feebly interacts with light and matter. Many new experiments have emerged over the last decade to test this hypothesis, involving state-of-the-art microwave cavities, precision nuclear magnetic resonance (NMR) measurements, dark matter “radios,” and synchronized global networks of atomic clocks, magnetometers, and interferometers. The editors have gathered leading experts from around the world to present the theories motivating these searches, evidence about dark matter from astrophysics, and the diverse experimental techniques employed in searches for ultralight bosonic dark matter. The text provides a comprehensive and accessible introduction to this blossoming field of research for advanced undergraduates, beginning graduate students, or anyone new to the field, with tutorials and solved problems in every chapter. The multifaceted nature of the research – combining ideas and methods from atomic, molecular, and optical physics, nuclear physics, condensed matter physics, electrical engineering, particle physics, astrophysics, and cosmology – makes this introductory approach attractive for beginning researchers as well as members of the broader scientific community. This is an open access book.
Download or read book Microwave Cavities and Detectors for Axion Research written by Gianpaolo Carosi and published by Springer Nature. This book was released on 2020-07-20 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nature of dark matter remains one of the preeminent mysteries in physics and cosmology. It appears to require the existence of new particles whose interactions with ordinary matter are extraordinarily feeble. One well-motivated candidate is the axion, an extraordinarily light neutral particle that may possibly be detected by looking for their conversion to detectable microwaves in the presence of a strong magnetic field. This has led to a number of experimental searches that are beginning to probe plausible axion model space and may reveal the axion in the near future. These proceedings discuss the challenges of designing and operating tunable resonant cavities and detectors at ultralow temperatures. The topics discussed here have potential application far beyond the field of dark matter detection and may be applied to resonant cavities for accelerators as well as designing superconducting detectors for quantum information and computing applications. This work is intended for graduate students and researchers interested in learning the unique requirements for designing and operating microwave cavities and detectors for direct axion searches and to introduce several proposed experimental concepts that are still in the prototype stage.

Available in PDF, EPUB and Kindle. Book excerpt: Discovering dark matter is one of the great challenges in contemporary physics. Successive generations of experiments -- each more impressive and sophisticated than the last -- have all failed to uncover dark matter's most basic properties. We have abundant evidence suggesting that dark matter exists, but we do not know the identity of the particle(s) that make up dark matter (let alone their mass, lifetime, spin, or coupling to other particles). In spite of decades of fruitless searching, the experimental physics community has not given up on identifying dark matter, since the payoff of a successful detection would be enormous. Characterizing dark matter would provide the first-ever opportunity to study a particle outside the Standard Model, and probing the structure of the Milky Way's dark matter halo would open up an entirely new avenue to study astrophysics and cosmology. These exciting prospects have motivated ever larger and more costly detectors, which acquire years' worth of data in order to accumulate sufficient statistics. Because of the intensive effort that has already been dedicated to finding dark matter, it is challenging to make progress without an expensive and large-scale experiment. This thesis describes a small part of the ongoing effort to make dark matter searches more tractable by adopting the techniques of quantum information science. Quantum information science has developed by leaps and bounds over the past decade, driven largely by the desire to build a quantum computer that exceeds the performance of any realistic classical computer. Although an unequivocal demonstration of such a "quantum speedup" remains elusive, the quantum information community has made impressive progress in preparing, manipulating, and detecting quantum states of light and matter. Leveraging such non-classical states in a dark matter detector allows it to greatly exceed the sensitivity of an equivalent, purely classical detector. A quantum speedup (in sensing, rather than computing) would dramatically reduce the size and cost of a useful dark matter detector. However, quantum states are fragile and difficult to manipulate, so substantial effort is needed to fully realize any non-classical advantage. This thesis is divided into two parts. In the first part, I design, build, and characterize the DM Radio Pathfinder, a modestly-scaled dark matter detector. I use the Pathfinder to set the best laboratory limits on a particular dark matter candidate particle, the hidden photon. Although the detector uses many techniques relevant to quantum information science, including cryogenics and sensitive superconducting circuits, it is a classical experiment which does not achieve any quantum speedup. In the second part of the thesis, I propose the RQU, a superconducting circuit that could plausibly achieve a quantum speedup in a dark matter experiment similar to the Pathfinder. I design and fabricate prototype RQUs and characterize their properties in several experiments. Finally, I propose a realistic path towards using RQUs to achieve a quantum speedup in a real dark matter detector.

Available in PDF, EPUB and Kindle. Book excerpt: We present direct detection constraints on the absorption of hidden-photon dark matter with particle masses in the range 1.2-30 eV$c^{-2}$ with the DAMIC experiment at SNOLAB. Under the assumption that the local dark matter is entirely constituted of hidden photons, the sensitivity to the kinetic mixing parameter $\kappa$ is competitive with constraints from solar emission, reaching a minimum value of 2.2$\times$$10^{-14}$ at 17 eV$c^{-2}$. These results are the most stringent direct detection constraints on hidden-photon dark matter with masses 3-12 eV$c^{-2}$ and the first demonstration of direct experimental sensitivity to ionization signals $

Available in PDF, EPUB and Kindle. Book excerpt: 'Clear and compact ... It's hard to fault as a brief, easily digestible introduction to some of the biggest questions in the Universe' Giles Sparrow, BBC Four's The Sky at Night , Best astronomy and space books of 2019: 5/5 All the matter and light we can see in the universe makes up a trivial 5 per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That 'something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets. By the 1990s we also knew that the expansion of the universe was accelerating. Something, named dark energy, is pushing it to expand faster and faster. Across the universe, this requires enough energy that the equivalent mass would be nearly fourteen times greater than all the visible material in existence. Brian Clegg explains this major conundrum in modern science and looks at how scientists are beginning to find solutions to it.
Download or read book Solar Astrophysics written by Peter V. Foukal and published by John Wiley & Sons. This book was released on 2008-09-26 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: This revised edition of Solar Astrophysics describes our current understanding of the sun - from its deepest interior, via the layers of the directly observable atmosphere to the solar wind, right out to its farthest extension into interstellar space. It includes a comprehensive account of the history of solar astrophysics, along with an overview of the key instruments throughout the various periods. In contrast to other books on this topic, the choice of material deals evenhandedly with the entire scope of important topics covered in solar research. The authors make the advances in our understanding of the sun accessible to students and non-specialists by way of careful use of relatively simple physical concepts. The book offers an incisive, reliable, and well-planned look at all that is fascinating and new in studies of the sun.
Download or read book The Isotropic Radio Background and Annihilating Dark Matter written by and published by . This book was released on 2012 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Observations by ARCADE-2 and other telescopes sensitive to low frequency radiation have revealed the presence of an isotropic radio background with a hard spectral index. The intensity of this observed background is found to exceed the flux predicted from astrophysical sources by a factor of approximately 5-6. In this article, we consider the possibility that annihilating dark matter particles provide the primary contribution to the observed isotropic radio background through the emission of synchrotron radiation from electron and positron annihilation products. For reasonable estimates of the magnetic fields present in clusters and galaxies, we find that dark matter could potentially account for the observed radio excess, but only if it annihilates mostly to electrons and/or muons, and only if it possesses a mass in the range of approximately 5-50 GeV. For such models, the annihilation cross section required to normalize the synchrotron signal to the observed excess is sigma v ̃(0.4-30) x 10-̂26 cm3̂/s, similar to the value predicted for a simple thermal relic (sigma v ̃3 x 10-̂26 cm3̂/s). We find that in any scenario in which dark matter annihilations are responsible for the observed excess radio emission, a significant fraction of the isotropic gamma ray background observed by Fermi must result from dark matter as well.

Download or read book Two phase Emission Detectors written by Dmitry Yu Akimov and published by World Scientific. This book was released on 2021-07-15 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the rapidly developing areas of modern experimental nuclear physics is non-accelerator experiments using low-background detectors. Such experiments, as a rule, are aimed at solving problems that are of fundamental importance for understanding the structure of the Universe, checking the Standard Model of elementary particles, and looking for new physics behind the observable world. The most interesting tasks include the search for dark matter in the form of new weakly interacting particles, the search for neutrinoless double beta decay, the determination of the magnetic moment of the neutrino, the study of neutrino oscillation and new types of interaction of elementary particles, such as coherent neutrino scattering off heavy nuclei.All these processes, occurring with extremely low cross sections, require the development of efficient large-mass detectors capable of detecting small energy releases down to individual ionization electrons. An effective method to do this is the emission method of detecting ionizing particles in two-phase media, which has been proposed at Moscow Engineering Physics Institute (MEPhI) 50 years ago. The origin of this technique can be traced to the research headed by Prof. Boris A Dolgoshein, whose study focus on the properties of condensed noble gases as a means to develop a tracking streamer chamber with a high-density working medium.This monograph, devoted exclusively to two-phase emission detectors, considers the technology's basic features while taking into account new developments introduced into experimental practice in the last ten years since the publication of its predecessor, Emission Detectors (Bolozdynya, 2010).
