[1103.3522] A spin-orbit coupled Bose-Einstein condensate.

Abstract Electronic spin-orbit coupling (SOC) is essential for various newly discovered phenomena in condensed-matter systems. In particular, one-dimensional topological heterostructures with SOC have been widely investigated in both theory and experiment for their distinct transport signatures indicating the presence of emergent Majorana fermions. Spin-orbit (SO) coupling—the interaction between a quantum particle's spin and its momentum—is ubiquitous in physical sys- tems. In condensed matter systems, SO coupling is crucial for the spin-Hall effect1,2and topological insulators3-5; it contributes to theelectronic properties ofmaterials suchas GaAs,andis import. Chiral spin textures are researched widely in condensed matter systems and show potential for spintronics and storage applications. Along with extensive condensed-matter studies of chiral spin textures, photonic counterparts of these textures have been observed in various optical systems with broken inversion symmetry. Unfortunately, the resemblances are only phenomenological.

Advanced capabilities for materials modelling with Quantum.

Further research indicates that the spin-orbit coupling and the band topology are highly adjustable. This work will greatly influence the research to ultracold atoms and condensed-matter physics. Topological states in condensed matter are well-known, even if not always recognized as such. The most famous example is likely the quantum Hall effect. In this case, time-reversal symmetry is broken by an external B → field. In the past decade, it was realized that spin-orbit coupling can be used to break time-reversal symmetry as well. In condensed matter systems, the doping concentration inhomogeneity leads to the Rashba spin-orbit interaction. This makes it possible to control the spin without the external magnetic field. By propagating the wave packet in systems exhibiting Rashba spin-orbit interactions, I discover several features such as spin separation, spin.

Department of Physics and Department of Energy Systems Research, Ajou University, Suwon 16499, Korea... the spin-orbit coupling between free exciton and donor to acceptor pair has been found to be 20 meV for polar <0001> and 40 meV for non-polar <1010>, and <1120> orientation, which shows a decreasing trend with an increase in temperature. The Goodenough-Kanamori rule, first formulated by Goodenough in 1955 (Goodenough 1955; Goodenough 1958) and subsequently provided more rigorous mathematical underpinning by Kanamori (1959), applies to interatomic spin-spin interactions between two atoms, each carrying a net spin, that are mediated by virtual electron transfers between the atoms (superexchange) and/or between a shared anion and.

SPEAR ITN - Spin-orbit materials, emergent phenomena and related.

Spin-orbit coupling (SOC) describes the relativistic interaction between the spin and momentum degrees of freedom of electrons, and is central to the rich phenomena observed in condensed matter systems. In recent years, new phases of matter have emerged from the interplay between SOC and low dimensionality, such as chiral spin textures and spin. Abstract: Electronic spin-orbit coupling (SOC) is essential for various newly discovered phenomena in condensed-matter systems. In particular, one-dimensional topological heterostructures with SOC have been widely investigated in both theory and experiment for their distinct transport signatures indicating the presence of emergent Majorana fermions. In the presence of spin–orbit coupling, the radial function is constructed by averaging between the two radial functions. These radial functions are read from the file containing the pseudopotential, in this case a fully-relativistic one. In this conventional basis, the corrective functional takes the form.

Observation of Axion Physics in Condensed Matter | The strongly spin.

Abstract Recently, the effects of spin-orbit coupling (SOC) in correlated materials have become one of the most actively studied subjects in condensed matter physics, as correlations and SOC together can lead to the discovery of new phases. Answer (1 of 3): I would just add to Professor Brewer's answer below by adding the (perhaps) obvious point that spin current can be thought of as a method of enhancing or reducing the flow of currents in small scale circuits without having to engineer new materials. This remarkable feat is done b. In conclusion, physics of spin-orbit coupling penetrated into numerous branches of condensed matter physics and uni ed them into an extensive, interconnected, and exciting eld including both fundamental problems and practical applications. I guess that our paper became successful because it was one of the rst, and timely, steps of this journey.

The strongly spin-momentum coupled electronic states in topological insulators (TI) are created by a combination of spin-orbit coupling and time-reversal symmetry. The surface conductance associated with these states is expected to be quantized and has a mathematical description identical to that used for fundamental particles known as. Since spin-orbit coupling effects will not be included, the electron spin will (for the moment) be suppressed. Semenoff investigated the tight-binding model with one orbital per site and a real hopping matrix element t ~ between nearest neighbors on different sublattices, and also considered the effect of an inversion-symmetry.

In past few decades, Rashba spin-orbit coupling (SOC) has been successfully employed for the emergence of exotic phenomena at the quantum oxide interfaces. In these systems, the combined effect of charge transfer, broken symmetries and SOC yields intriguing interfacial magnetism and transport properties.

We propose a realization of an antisymmetric spin-split band structure through magnetic phase transitions without spin-orbit coupling. It enables us to utilize it for a variety of magnetic-order-driven cross-correlated and nonreciprocal transport phenomena as similar to those in spin-orbit-coupling oriented systems. We unveil its general condition as an emergence of a bond-type magnetic.
