Book Synopsis Spin Squeezing and Non-linear Atom Interferometry with Bose-Einstein Condensates by : Christian Groß
Download or read book Spin Squeezing and Non-linear Atom Interferometry with Bose-Einstein Condensates written by Christian Groß and published by Springer Science & Business Media. This book was released on 2012-01-12 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interferometry, the most precise measurement technique known today, exploits the wave-like nature of the atoms or photons in the interferometer. As expected from the laws of quantum mechanics, the granular, particle-like features of the individually independent atoms or photons are responsible for the precision limit, the shot noise limit. However this “classical” bound is not fundamental and it is the aim of quantum metrology to overcome it by employing entanglement among the particles. This work reports on the realization of spin-squeezed states suitable for atom interferometry. Spin squeezing was generated on the basis of motional and spin degrees of freedom, whereby the latter allowed the implementation of a full interferometer with quantum-enhanced precision.
Book Synopsis Interferometry with Interacting Bose-Einstein Condensates in a Double-Well Potential by : Tarik Berrada
Download or read book Interferometry with Interacting Bose-Einstein Condensates in a Double-Well Potential written by Tarik Berrada and published by Springer. This book was released on 2015-12-17 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis demonstrates a full Mach–Zehnder interferometer with interacting Bose–Einstein condensates confined on an atom chip. It relies on the coherent manipulation of atoms trapped in a magnetic double-well potential, for which the author developed a novel type of beam splitter. Particle-wave duality enables the construction of interferometers for matter waves, which complement optical interferometers in precision measurement devices, both for technological applications and fundamental tests. This requires the development of atom-optics analogues to beam splitters, phase shifters and recombiners. Particle interactions in the Bose–Einstein condensate lead to a nonlinearity, absent in photon optics. This is exploited to generate a non-classical state with reduced atom-number fluctuations inside the interferometer. This state is then used to study the interaction-induced dephasing of the quantum superposition. The resulting coherence times are found to be a factor of three longer than expected for coherent states, highlighting the potential of entanglement as a resource for quantum-enhanced metrology.

Book Synopsis Space Infrastructures: From Risk to Resilience Governance by : U. Tatar
Download or read book Space Infrastructures: From Risk to Resilience Governance written by U. Tatar and published by IOS Press. This book was released on 2020-04-17 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space-critical infrastructures represent an interdependent system of systems consisting of workforce, environment, facilities, and multidirectional interactions. These are essential for the maintenance of vital societal functions such as health, safety, security, mobility, and the economic and social well-being of people, and their destruction or disruption would have a significant impact on society as a whole. In all, 79 nations and government consortia currently operate satellites, with 11 countries operating 22 launch sites. Despite creating new challenges, this multi-actor environment offers opportunities for international cooperation, but making the most of these opportunities requires a holistic approach to space-critical infrastructure, away from strictly defined space technologies and towards understanding the resilience of complex systems and how they are intertwined in reality. This book presents papers from the NATO Advanced Research Workshop (ARW), entitled Critical Space Infrastructure: From Vulnerabilities and Threats to Resilience, held in Norfolk, Virginia, USA from 21-22 May 2019. The ARW brought together representatives from academia, industry, and international organizations in an effort to deepen scientific and technological understanding of space-critical infrastructures and explore the implications for national and international space security and resilience. It examined space as a critical infrastructure from a multidisciplinary perspective in accordance with NATO’s Strategic Concept. The 29 chapters in the book are divided into six sections covering space infrastructure: governance; cybersecurity; risk, resiliency and complexity; emerging technologies such as block chain, artificial intelligence and quantum computing; application domains; and national approaches and applications.

Download or read book Asteroids written by Martin Elvis and published by Yale University Press. This book was released on 2021-06-08 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unique, wide-ranging examination of asteroid exploration and our future in space Human travel into space is an enormously expensive and unforgiving endeavor. So why go? In this accessible and authoritative book, astrophysicist Martin Elvis argues that the answer is asteroid exploration, for the strong motives of love, fear, and greed. Elvis’s personal motivation is one of scientific love—asteroid investigations may teach us about the composition of the solar system and the origins of life. A more compelling reason may be fear—of a dinosaur killer–sized asteroid hitting our planet. Finally, Elvis maintains, we should consider greed: asteroids likely hold vast riches, such as large platinum deposits, and mining them could provide both a new industry and a funding source for bolder space exploration. Elvis explains how each motive can be satisfied, and how they help one another. From the origins of life, to “space billiards,” and space sports, Elvis looks at how asteroids may be used in the not-so-distant future.

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.

Book Synopsis Recapturing a Future for Space Exploration by : National Research Council
Download or read book Recapturing a Future for Space Exploration written by National Research Council and published by National Academies Press. This book was released on 2012-01-30 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than four decades have passed since a human first set foot on the Moon. Great strides have been made in our understanding of what is required to support an enduring human presence in space, as evidenced by progressively more advanced orbiting human outposts, culminating in the current International Space Station (ISS). However, of the more than 500 humans who have so far ventured into space, most have gone only as far as near-Earth orbit, and none have traveled beyond the orbit of the Moon. Achieving humans' further progress into the solar system had proved far more difficult than imagined in the heady days of the Apollo missions, but the potential rewards remain substantial. During its more than 50-year history, NASA's success in human space exploration has depended on the agency's ability to effectively address a wide range of biomedical, engineering, physical science, and related obstacles-an achievement made possible by NASA's strong and productive commitments to life and physical sciences research for human space exploration, and by its use of human space exploration infrastructures for scientific discovery. The Committee for the Decadal Survey of Biological and Physical Sciences acknowledges the many achievements of NASA, which are all the more remarkable given budgetary challenges and changing directions within the agency. In the past decade, however, a consequence of those challenges has been a life and physical sciences research program that was dramatically reduced in both scale and scope, with the result that the agency is poorly positioned to take full advantage of the scientific opportunities offered by the now fully equipped and staffed ISS laboratory, or to effectively pursue the scientific research needed to support the development of advanced human exploration capabilities. Although its review has left it deeply concerned about the current state of NASA's life and physical sciences research, the Committee for the Decadal Survey on Biological and Physical Sciences in Space is nevertheless convinced that a focused science and engineering program can achieve successes that will bring the space community, the U.S. public, and policymakers to an understanding that we are ready for the next significant phase of human space exploration. The goal of this report is to lay out steps and develop a forward-looking portfolio of research that will provide the basis for recapturing the excitement and value of human spaceflight-thereby enabling the U.S. space program to deliver on new exploration initiatives that serve the nation, excite the public, and place the United States again at the forefront of space exploration for the global good.
