Book Synopsis Fluctuations and Localization in Mesoscopic Electron Systems by : Martin Janssen
Download or read book Fluctuations and Localization in Mesoscopic Electron Systems written by Martin Janssen and published by World Scientific. This book was released on 2001 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: The quantum phenomena of tunneling and interference show up not only in the microscopic world of atoms and molecules, but also in cold materials of the real world, such as metals and semiconductors. Though not fully macroscopic, such mesoscopic systems contain a huge number of particles, and the holistic nature of quantum mechanics becomes evident already in simple electronic measurements. The measured quantity fluctuates as a function of applied fields in an unpredictable, yet reproducible way. Despite this fingerprint character of fluctuations, their statistical properties are universal, i.e. they are the same for a large class of different mesoscopic systems, having only very few parameters in common. Localization of electrons is a dramatic effect of destructive interference. As a consequence a metal can become an insulator while reaching mesoscopic scales. Based on elementary quantum and statistical physics, this text introduces the theory of mesoscopic electron systems. It focuses on universal characteristics of fluctuations and on the localization mechanism. General concepts and methods are stressed, such as scaling laws for distribution functions. Tools from condensed matter theory are used flexibly. Involved technical details are skipped so as to present a broad overview of the field, including topics like quantum dots, the quantum Hall effect and a number of the most recent developments.
Book Synopsis Complexity from Microscopic to Macroscopic Scales: Coherence and Large Deviations by : A.T. Skjeltorp
Download or read book Complexity from Microscopic to Macroscopic Scales: Coherence and Large Deviations written by A.T. Skjeltorp and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many mesoscopic systems display `adaptive' behaviour - changes in some physical property that results from a small change in an internal or external driving force. There is a kind of progression in adaptive phenomena, from quantum mesoscopics to complex, evolved cooperative systems and large scale events like turbulence. The field of mesoscopic magnetism, especially quantum coherence and quantum tunnelling in spin systems, and the coupling between mesoscopic magnetism and mesoscopic transport is currently a very active area of solid state physics. `Dephasing' is an important concept in mesoscopic systems like these. A basic question is the limit at which quantum mechanics breaks down and what it can be replaced with. Another interesting crossover is that between complexity and large excursions or events, with turbulence as a prototype example. The book also contains a discussion of finance. Qualitatively speaking, turbulence and financial markets are apparently similar, so our understanding of turbulence may be relevant to understanding price fluctuations.
Book Synopsis Quantum Computing and Quantum Bits in Mesoscopic Systems by : Anthony Leggett
Download or read book Quantum Computing and Quantum Bits in Mesoscopic Systems written by Anthony Leggett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum information science is a new field of science and technology which requires the collaboration of researchers coming from different fields of physics, mathematics, and engineering: both theoretical and applied. Quantum Computing and Quantum Bits in Mesoscopic Systems addresses fundamental aspects of quantum physics, enhancing the connection between the quantum behavior of macroscopic systems and information theory. In addition to theoretical quantum physics, the book comprehensively explores practical implementation of quantum computing and information processing devices. On the experimental side, this book reports on recent and previous observations of quantum behavior in several physical systems, coherently coupled Bose-Einstein condensates, quantum dots, superconducting quantum interference devices, Cooper pair boxes, and electron pumps in the context of the Josephson effect. In these systems, the book discusses all required steps, from fabrication through characterization to the final basic implementation for quantum computing.
Book Synopsis Macroscopic Quantum Coherence and Quantum Computing by : Dmitri V. Averin
Download or read book Macroscopic Quantum Coherence and Quantum Computing written by Dmitri V. Averin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is an outgrowth of the Second International Workshop on Macroscopic Quantum Coherence and Computing held in Napoli, Italy, in June 2000. This workshop gathered a number of experts from the major Universities and Research Institutions of several countries. The choice of the location, which recognizes the role and the traditions of Naples in this field, guaranteed the participants a stimulating atmosphere. The aim of the workshop has been to report on the recent theoretical and experimental results on the macroscopic quantum coherence of macroscopic systems. Particular attention was devoted to Josephson devices. The correlation with other atomic and molecular systems, exhibiting a macroscopic quantum behaviour, was also discussed. The seminars provided both historical overview and recent theoretical ground on the topic, as well as information on new experimental results relative to the quantum computing area. The first workshop on this topic, held in Napoli in 1998, has been ennobled by important reports on observations of Macroscopic Quantum Coherence in mesoscopic systems. The current workshop proposed, among many stimulating results, the first observations of Macroscopic Quantum Coherence between macroscopically distinct fluxoid states in rf SQUIDs, 20 years after the Leggett's proposal to experimentally test the quantum behavior of macroscopic systems. Reports on observations of quantum behaviour in molecular and magnetic systems, small Josephson devices, quantum dots have also been particularly stimulating in view of the realization of several possible q-bits.
Book Synopsis Introduction to Mesoscopic Physics by : Joseph Imry
Download or read book Introduction to Mesoscopic Physics written by Joseph Imry and published by Oxford University Press. This book was released on 1997-02-13 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Mesoscopic physics" refers to the physics of structures larger than a nanometer (one billionth of a meter) but smaller than a micrometer (one millionth of a meter). This size range is the stage on which the exciting new research on submicroscopic and electronic and mechanical devices is being done. This research often crosses the boundary between physics and engineering, since engineering such tiny electronic components requires a firm grasp of quantum physics. Applications for the future may include such wonders as microscopic robot surgeons that travel through the blood stream to repair clogged arteries, submicroscopic actuators and builders, and supercomputers that fit on the head of a pin. The world of the future is being planned and built by physicists, engineers, and chemists working in the microscopic realm. This book can be used as the main text in a course on mesoscopic physics or as a supplementary text in electronic devices, semiconductor devices, and condensed matter physics courses.
Book Synopsis Quantum Mesoscopic Phenomena and Mesoscopic Devices in Microelectronics by : Igor O. Kulik
Download or read book Quantum Mesoscopic Phenomena and Mesoscopic Devices in Microelectronics written by Igor O. Kulik and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum mechanical laws are well documented at the level of a single or a few atoms and are here extended to systems containing 102 to 1010 electrons - still much smaller than the usual macroscopic objects, but behaving in a manner similar to a single atom. Besides the purely theoretical interest, such systems pose a challenge to the achievement of the ultimate microelectronic applications. The present volume presents an up-to-date account of the physics, technology and expected applications of quantum effects in solid-state mesoscopic structures. Physical phenomena include the Aharonov-Bohm effect, persistent currents, Coulomb blockade and Coulomb oscillations in single electron devices, Andreev reflections and the Josephson effect in superconductor/normal/superconductor systems, shot noise suppression in microcontacts and contact resistance quantisation, and overall quantum coherence in mesoscopic and nanoscopic structures related to the emerging physics of quantum computation in the solid-state environment.

Book Synopsis Quantum Phenomena in Mesoscopic Systems by : B. Altshuler
Download or read book Quantum Phenomena in Mesoscopic Systems written by B. Altshuler and published by IOS Press. This book was released on 2004-01-28 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a snapshot of the vision shared by outstanding scientists on the key theoretical and experimental issues in Mesoscopic Physics. Quantum properties of electrons in solid state devices and transport in semiconducting and superconducting low-dimensional systems, are discussed, as well as the basis of quantum computing (entanglement, noise decoherence and read-out). Each chapter collects the material presented at a Varenna School course of last year, by leading experts in the field. The reader gets a flavor, how theorists and experimentalists are paving the way to the physical realization of solid state qubits, the basic units of the new logic and memory elements for quantum processing. He will be surprised in finding that mesoscopic solid state devices, which were invented just yesterday ( think of the Single Electron Transistor, or the Cooper Pair Box) are currently used as charge-sensing applications in the equipment of frontier research laboratories. These devices contribute as probing systems to produce evidence on still unsettled questions in topics like the metal-insulator transition in disordered two dimensional systems, quantum Hall conductance in heterostructures, or Kondo conductance in quantum dots.

Book Synopsis Macrosopic Manifestations and Coherent Manipulations of Quantum Mesoscopic Systems by : Joel Stettenheim
Download or read book Macrosopic Manifestations and Coherent Manipulations of Quantum Mesoscopic Systems written by Joel Stettenheim and published by . This book was released on 2012 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mesoscopic physics is a fascinating realm in which classical descriptions are usefully applied but wherein quantum behavior is strongly manifest. As such, it is an ideal arena for exploring the interplay between the classical and quantum worlds and the ways in which we can effectively control and coherently manipulate quantum systems with macrosopic inputs. Focusing on coupling between macroscopic and quantum systems, the first area of research presented in this thesis is our discovery and exploration of a naturally occurring feedback loop in which the mechanical motion of a macroscopic semiconductor crystal is controlled by the statistical fluctuations of tunneling electrons [1]. The second area of research presented in this thesis is a decription of our implementation of a system for the coherent manipulation of electronic spins using electron spin resonance. Consisting of a one-dimensional conduction channel and a tunable tunnel barrier, (quantum point contacts) QPCs are canonical quantum systems that display a rich array of physics [2-6]. In our GaAs system through piezoelectric coupling, the QPC current I probes the deformation of the host crystal and generates a naturally occurring feedback loop. Such systems with coupled mechanical and optical or electrical degrees of freedom [7], [8] have fascinating dynamics that, through macroscopic manifestations of quantum behavior [9], provide new insights into the transition between the classical and quantum worlds. The feedback, which is naturally associated with backaction, has been predicted to have significant consequences for the noise of a detector coupled to a mechanical oscillator [10], [11]. In our case the souce of the backaction is shot noise, and intrinsic noise source due to the stochastic partitioning of discrete charge flow by the QPC tunnel barrier. While ESR is conceptually relatively straight-forward, it is technically challenging to generate an ac magnetic field B[subscript ac] large enough to manipulate spins fast enough to perform meaningful quantum computation operations. In addition it is important to minimize the ac electric field E[subscript ac] which can cause sample heating and induce unwanted photon assisted transitions. As described in Chapter 3 in our ESR system, we address these issues by create a standing wave in a stripline and place the sample at a peak in B[subscript ac] and node in E[subscript ac].
