Available in PDF, EPUB and Kindle. Book excerpt: We are witnessing remarkable progress in building large and controllable quantum systems. At the forefront of this development are laser-cooled atoms, which can be used as atomic clocks, sensitive measurement probes or quantum computing platforms. A necessary ingredient of many computation and metrology schemes is the ability to have local and dynamical control of interactions between atoms. In this thesis, I present a platform based on highly excited Rydberg states of cesium atoms. We realize long-range optically controlled Ising interactions in a cloud of cold cesium atoms by coupling the atomic ground state to a Rydberg state. By adding a microwave coupling between the clock states of cesium, we emulate a transverse-field Ising model and detect dynamical signatures of the paramagnetic-ferromagnetic phase transition. I present work on producing spin-squeezed states, in which quantum correlations enable higher measurement precision than possible with an uncorrelated state. I show the first measurement of spin squeezing with the local Ising interactions, demonstrating a factor $\xi^2=\num{0.80(7)}$ reduction in phase variance below the projection noise limit. I present prospects for improving spin squeezing in this system, by minimizing sources of loss, trapping atoms in a regular array and utilizing the transverse field. Finally, I propose an application of optically controlled Ising interactions to the computational problem of number partitioning, where a hardware-efficient encoding in a central spin system enables solutions to be found via Grover's algorithm. The simulated performance of the algorithm exhibits a quantum speedup in a system of Rydberg-dressed atoms, paving the way for demonstrations in near-term experiments.

Download or read book Quantum Gas Experiments Exploring Many body States written by Paivi Torma and published by World Scientific. This book was released on 2014-09-16 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum phenomena of many-particle systems are fascinating in their complexity and are consequently not fully understood and largely untapped in terms of practical applications. Ultracold gases provide a unique platform to build up model systems of quantum many-body physics with highly controlled microscopic constituents. In this way, many-body quantum phenomena can be investigated with an unprecedented level of precision, and control and models that cannot be solved with present day computers may be studied using ultracold gases as a quantum simulator.This book addresses the need for a comprehensive description of the most important advanced experimental methods and techniques that have been developed along with the theoretical framework in a clear and applicable format. The focus is on methods that are especially crucial in probing and understanding the many-body nature of the quantum phenomena in ultracold gases and most topics are covered both from a theoretical and experimental viewpoint, with interrelated chapters written by experts from both sides of research.Graduate students and post-doctoral researches working on ultracold gases will benefit from this book, as well as researchers from other fields who wish to gain an overview of the recent fascinating developments in this very dynamically evolving field. Sufficient level of both detailed high level research and a pedagogical approach is maintained throughout the book so as to be of value to those entering the field as well as advanced researchers. Furthermore, both experimentalists and theorists will benefit from the book; close collaboration between the two are continuously driving the field to a very high level and will be strengthened to continue the important progress yet to be made in the field.

This book was released on 2011-06-28 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary focus of this thesis is to theoretically describe nanokelvin experiments in cold atomic gases, which offer the potential to revolutionize our understanding of strongly correlated many-body systems. The thesis attacks major challenges of the field: it proposes and analyzes experimental protocols to create new and interesting states of matter and introduces theoretical techniques to describe probes of these states. The phenomena considered include the fractional quantum Hall effect, spectroscopy of strongly correlated states, and quantum criticality, among others. The thesis also clarifies experiments on disordered quantum solids, which display a variety of exotic phenomena and are candidates to exhibit so-called "supersolidity." It collects experimental results and constrains their interpretation through theoretical considerations. This Doctoral Thesis has been accepted by Cornell University, Ithaca, USA.

Available in PDF, EPUB and Kindle. Book excerpt: Recent years have seen tremendous progress in research on cold and controlled molecular collisions, both in theory and in experiment. The advent of techniques to prepare cold and ultracold molecules and ions, to store them in optical lattices or in charged quasicristalline structures, and to use them in crossed or merged beam experiments have opened many new possibilities to study the most fundamental aspects of molecular interactions. At the same time, theoretical work has made progress in tackling these problems and accurately describing quantum effects in complex systems, and in proposing viable options to control chemical reactions at ultralow energies. Through tutorials on both the theoretical and experimental aspects of research in cold and ultracold molecular collisions, this book provides advanced undergraduate students, graduate students and researchers with the foundations needed to understand this exciting field.
