Available in PDF, EPUB and Kindle. Book excerpt: Electrons and ions have been used for over 40 years as probes to investigate the fascinating properties of helium liquids. The study of the transport properties of microscopic charge carriers sheds light on superfluidity, on quantum hydrodynamics, and on the interactions with collective excitations in quantum liquids. The structure of the probes themselves depends on their coupling with the liquid environment in a way that gives further insight into the microscopic behavior of the liquid in different thermodynamic conditions, such as in the superfluid phase, in the normal phase, or near the liquid-vapor critical point. This book provides a comprehensive review of the experiments and theories of transport properties of charge carriers in liquid helium. It is a subject about which no other monograph exists to date. The book is intended for graduate and postgraduate students and for condensed matter physicists who will benefit from its completeness and accuracy.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes novel methods and experiments for investigating electrons floating on the surface of liquid helium by utilizing surface acoustic wave (SAW) techniques. Electrons on helium are an ideal system for studying a non-degenerate two-dimensional electron system (2DES), Wigner cyrstallization, and the coupling of a 2DES to a bosonic field. The electrons in this system are also interesting with regard to quantum information science due to their predicted long coherence time. An evanescent coupling of electrons to high-frequency SAWs submerged beneath the liquid helium provides a probe of the high-frequency conductivity of the 2DES and can be used to create SAW-driven charge transport of the electron system and opens the door for resonant interaction between SAWs and collective modes of the electron system.Before employing SAW techniques, we first examined the low-frequency transport properties of electrons on helium at several tens of kHz using a lock-in method, which confirms the realization of a stable and reproducible 2D electron system on liquid helium. Furthermore, taking advantage of the capactive coupling of the electron layer and submerged electrodes, we are able to precisely control AC current flows in the 2DES and achieve the analog of a field-effect transistor with electrons on helium and demonstrate the applicability of long wavelength transport at high temperature and low electron density.By coupling SAWs to the system, the SAW-liquid helium interaction is investigated by measuring the loss of SAW energy into the liquid. We find that the attenuation of the SAW in bulk liquid helium is dominated by the radiation of compressional wave into the liquid, in a good agreement with theory and previous experiments. However, for sufficiently thin helium coverage (several tens of nm), the attenuation anomalously increases beyond that measured in a thick helium layer. This novel phenomenon is likely associated with the electrostrictive actuation of the helium surface. Furthermore, this study is a prerequisite for quantitatively analyzing the SAW measurement results obtained for the 2DES on the liquid helium surface.In last two chapters, we present a detailed study of the SAW coupling to surface electrons floating above liquid helium in both the weak and the strong coupling regimes. These experiments demonstrate find acoustoelectric charge transport and the SAW attenuation in this system of electrons on helium for the first time. These experiments open the door to a new class of studies with this system. These include quantized charge pumping, the possibility of electrical metrology, and ultimately single electron state transfer with electrons floating on the helium. Also, this coupled system can be utilized to study a commensurate-incommensurate transition of the 2DES under a time-dependent periodic electric potential (i.e. a standing piezoelectric SAW). Furthermore, the high-sensitivity of the SAW to the spatial structure of the 2DES can provide a new method of studying the 2D phase transition in the electrons on helium system.

Available in PDF, EPUB and Kindle. Book excerpt: Bibliographic Guide to Refrigeration 1965-1968 is a bibliographic guide to all the documents abstracted in the International Institute of Refrigeration Bulletin during the period 1965-1968. The references include nearly 7,000 reports, articles, and communications, classified according to subjects, and followed by a listing of books. This book is divided into 10 parts and begins with a listing of references on thermodynamics, heat transfer, and other basic physical phenomena relating to refrigeration, including desiccation and measurements of temperature, humidity, and pressure. The next sections are devoted to the physics of low temperatures and cryogenics; production and distribution of cold; refrigerating plants (mainly in the food domain); and refrigerated transport and packaging. Other references deal with air conditioning and heat pumps; and industrial, biological, medical, and agricultural applications of refrigeration. The final section focuses on standards and regulations, economics and statistics, and education and trade activities in the refrigeration industry. This guide is intended to assist researchers, engineers, manufacturers, and operators who are in either constant or occasional contact with the refrigeration domain.

Available in PDF, EPUB and Kindle. Book excerpt: New, unexpected and largely unexplored physical phenomena occur in systems cooled to very low temperatures. The background temperature in the universe is approximately 2.7 K, but much lower temperatures have now been obtained in the laboratory. This book reviews the progress in a number of related fields in which the common themes are low temperatures and molecules, not atoms.This book brings together, for the first time, the results of recent research in areas ranging from the chemistry of cold interstellar clouds (10-20 K), through laboratory studies of the spectroscopy and kinetics of ions, radicals and molecules, to studies of molecules in liquid helium droplets, to attempts to create molecular (as distinct from atomic) Bose-Einstein condensates.The chapters fall into two parts, the first one dealing with low-temperature experiments and environments (ca. 1-20 K). In the context of this book, these chapters can be said to deal with relatively mature fields. The second part deals with very low temperatures and very cold molecules. Here, more emphasis is placed on the methods employed to generate samples of molecules at extremely low (1 K) temperatures.
