Download or read book Spin Physics in Semiconductors written by Mikhail I. Dyakonov and published by Springer Science & Business Media. This book was released on 2008-07-18 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this collective book is to present a non-exhaustive survey of sp- related phenomena in semiconductors with a focus on recent research. In some sense it may be regarded as an updated version of theOpticalOrientation book, which was entirely devoted to spin physics in bulk semiconductors. During the 24 years that have elapsed, we have witnessed, on the one hand, an extraordinary development in the wonderful semiconductor physics in two dim- sions with the accompanying revolutionary applications. On the other hand, during the last maybe 15 years there was a strong revival in the interest in spin phen- ena, in particular in low-dimensional semiconductor structures. While in the 1970s and 1980s the entire world population of researchers in the ?eld never exceeded 20 persons, now it can be counted by the hundreds and the number of publications by the thousands. This explosive growth is stimulated, to a large extent, by the hopes that the electron and/or nuclear spins in a semiconductor will help to accomplish the dream of factorizing large numbers by quantum computing and eventually to develop a new spin-based electronics, or “spintronics”. Whether any of this will happen or not, still remains to be seen. Anyway, these ideas have resulted in a large body of interesting and exciting research, which is a good thing by itself. The ?eld of spin physics in semiconductors is extremely rich and interesting with many spectacular effects in optics and transport.

Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, we present detailed studies on the nuclear spin dynamics and relaxation, electron spin decoherence, and non-equilibrium electronic transport in Kondo regime for semiconductor quantum dots. We calculate the coefficients of nuclear spin diffusion with two different methods. It is shown that hyperfine interaction decreases the diffusion coefficients dramatically. We discuss the performance of the coherent spin transfer with the nuclear quantum memory using quantum dot, and calculate the operation fidelity due to nuclear spin dipolar coupling. We also study the possible nuclear spin polarization and relaxation mechanism in a spin-blocked double-dot, and qualitatively explain some of the recent experimental results. We study the electron spin decoherence time (T 2) resulting from hyperfine coupling with the equation-of-motion approach. We show that the transverse electron spin undergoes a complete decay in the long time limit by including higher-order processes. Finally we develop a real-time density matrix method and apply it to study the non-equilibrium electron transport through quantum dots in the context of Kondo effect.

Download or read book Spins in Optically Active Quantum Dots written by Oliver Gywat and published by John Wiley & Sons. This book was released on 2010-02-01 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Filling a gap in the literature, this up-to-date introduction to the field provides an overview of current experimental techniques, basic theoretical concepts, and sample fabrication methods. Following an introduction, this monograph deals with optically active quantum dots and their integration into electro-optical devices, before looking at the theory of quantum confined states and quantum dots interacting with the radiation field. Final chapters cover spin-spin interaction in quantum dots as well as spin and charge states, showing how to use single spins for break-through quantum computation. A conclusion and outlook round off the volume. The result is a primer providing the essential basic knowledge necessary for young researchers entering the field, as well as semiconductor and theoretical physicists, PhD students in physics and material sciences, electrical engineers and materials scientists.

Download or read book Dynamics of Encoded Spin Qubits in Semiconductor Quantum Dots written by Jo-Tzu Hung and published by . This book was released on 2015 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation aims to clarify the dynamics of encoded spin qubits in semiconductor quantum dots. The major part of the dissertation features a study of pure dephasing of multiple-electron spin states in coupled semiconductor quantum dots due to hyperfine interaction. With a perturbation approach, this work can effectively describe the multiple-electron spin states, and calculates the dynamics of qubit free evolution and with the application of dynamical decoupling within reasonable approximation. The derived hyperfine induced dephasing can offer an understanding of the decoherence of a pseudospin qubit, and is also relevant to the fidelity of gate operations. The remaining part of the dissertation presents the relaxation dynamics of spin-orbit-hybrized states in a nanowire quantum dot due to electrical noises. To deal with strong spin-orbit coupling, the employed treatment starts by solving the Schr©œdinger equation for a spinor, and the author wishes to develop a convenient and effective tool to describe the spin-orbit-hybrized states.
