The design of epitaxial interfaces is a pivotal way to engineer artificial structures where new electronic phases can emerge. Here, we report a systematic emergence of an interfacial superconducting state in epitaxial heterostructures of LaTiO3 and K

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

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

Publikováno v: Physical Review Research, Vol 2, Iss 1, p 013036 (2020)

We show that attractive spinor Bose-Einstein condensates under the action of spin-orbit coupling (SOC) and Zeeman splitting form self-sustained stable two- and three-dimensional (2D and 3D) states in free space, even when SOC acts in a lower-dimensio

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
