Ground-state properties of spin-orbit-coupled dipolar Bose-Einstein condensates with in-plane gradient magnetic field

The effects of spin-orbit coupling (SOC), dipole-dipole interaction (DDI) and the in-plane quadrupole field on the ground-state structures and spin textures of the system are systematically analyzed and discussed. Expand abstract.

Topological excitations in rotating Bose-Einstein condensates with Rashba-Dresselhaus spin-orbit coupling in a two-dimensional optical lattice

We study the ground-state configurations and spin textures of rotating two-component Bose-Einstein condensates (BECs) with Rashba-Dresselhaus spin-orbit coupling (RD-SOC), which are confined in a two-dimensional (2D) optical lattice plus a 2D harmonic trap. Expand abstract.

Giant anisotropy of Gilbert damping in a Rashba honeycomb antiferromagnet

Giant Gilbert damping anisotropy is identified as a signature of strong Rashba spin-orbit coupling in a two-dimensional antiferromagnet on a honeycomb lattice. Expand abstract.

Internal magnetic fields, spin-orbit coupling, and orbital period modulation in close binary systems

We introduce a new model to explain the modulation of the orbital period observed in close stellar binary systems based on an angular momentum exchange between the spin of the active component and the orbital motion. Expand abstract.

Efficient spin-orbit torque switching with non-epitaxial chalcogenide heterostructures

The spin-orbit torques (SOTs) generated from topological insulators (TIs) have gained increasing attention in recent years. Expand abstract.

Resolving Ultra-Fast Spin-Orbit Dynamics in Heavy Many-Electron Atoms

We use R-Matrix with Time-dependence (RMT) theory, with spin-orbit effects included, to study krypton irradiated by two time-delayed XUV ultrashort pulses. Expand abstract.

Ferromagnetic fluctuations in the Rashba-Hubbard model

We study the occurrence and the origin of ferromagnetic fluctuations in the longitudinal spin susceptibility of the $t$-$t'$-Rashba-Hubbard model on the square lattice. Expand abstract.

Excitonic Magnetism at the intersection of Spin-orbit coupling and crystal-field splitting

Excitonic magnetism involving superpositions of singlet and triplet states is expected to arise for two holes in strongly correlated and spin-orbit coupled $t_{2g}$ orbitals. Expand abstract.

Global phase diagram of a spin-orbital Kondo impurity model and the suppression of Fermi-liquid scale

Many correlated metallic materials are described by Landau Fermi-liquid theory at low energies, but for Hund metals the Fermi-liquid coherence scale $T_{\text{FL}}$ is found to be surprisingly small. Expand abstract.

Squeezing Magnetic Modulations by Enhanced Spin-Orbit Coupling of 4d Electrons in the Polar Semiconductor GaMo$_4$S$_8$

In polar magnets with axial symmetry, such as GaV$_4$S$_8$, GaV$_4$Se$_8$ and VOSe$_2$O$_5$, the N\'eel-type skyrmion lattice state, formed by the superposition of cycloidal modulations, was found stable over extended temperature ranges, even down to zero Kelvin. Expand abstract.
