Terahertz (THz) vector beams with spatially textured polarization are proposed to steer the spin and spatial distributions of two interacting electrons in a quantum dot. We study theoretically the spatiotemporal evolution of the spin and the charge-c

High-fidelity non-adiabatic cutting and stitching of a spin chain via local control

Autor: P V Pyshkin, E Ya Sherman, J Q You, Lian-Ao Wu

Publikováno v: New Journal of Physics, Vol 20, Iss 10, p 105006 (2018)

We propose and analyze, focusing on non-adiabatic effects, a technique of manipulating quantum spin systems based on local ‘cutting’ and ‘stitching’ of the Heisenberg exchange coupling between the spins. This first operation is cutting of a b

von Neumann spin measurements with Rashba fields

Autor: E Ya Sherman, D Sokolovski

Publikováno v: New Journal of Physics, Vol 16, Iss 1, p 015013 (2014)

We show that dynamics in the spin–orbit coupling field simulate the von Neumann measurement of a particle spin. We demonstrate how the measurement influences the spin and coordinate evolution of a particle by comparing two examples of such a proced

Interplay of spin–orbit coupling and Coulomb interaction in ZnO-based electron system

Autor: D. Maryenko, M. Kawamura, A. Ernst, V. K. Dugaev, E. Ya. Sherman, M. Kriener, M. S. Bahramy, Y. Kozuka, M. Kawasaki

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-6 (2021)

The coexistence of spin–orbit and electron–electron interactions is expected to give rise to novel electronic phases and spin textures, but it is challenging to achieve in experiments. Here the authors realize such a regime in a two-dimensional e

Spin-orbit coupling (SOC) is pivotal for various fundamental spin-dependent phenomena in solids and their technological applications. In semiconductors, these phenomena have been so far studied in relatively weak electron-electron interaction regimes
