Introduction.| In recent times, topological phases in insulators and superconductors are extensively studied theoretically [1{6] as well as experimentally [7,8]. The conventional bulk boundary correspondence (BBC) for rst-order topological phase is generalized for n(>1)th-order topological insulator (TI) [9{20] and topological su.

Topological phases in a two-dimensional lattice: Magnetic field versus spin-orbit coupling Abstract In this work, we explore the rich variety of two-dimensional topological phases that arise when considering the competing effects of spin-orbit couplings, Zeeman splitting, and uniform magnetic fields. Laser-induced spin-orbit coupling in ultracold atoms can be tuned, in contrast to the fixed spin-orbit coupling in materials like topological insulators.... the spin-orbit coupling should allow scientists to explore the emergence of topological insulators and other so-called topological phases of matter, such as fractional quantum Hall states. A spin-dependent topological deflection of classical light propagates along a smooth helical trajectory. Spin-orbit interaction is a weak coupling between intrinsic (spin) and extrinsic (orbital motion) degrees of freedom of spinning particles. It implies mutual conversion between a particle's spin and orbital angular momenta.

Recently, searching large-bulk band gap topological insulator (TI) is under intensive study. Through k·P theory and first-principles calculations analysis on antimonene, we find that α-phase antimonene can be tuned to a 2D TI under an in-plane anisotropic strain and the magnitude of direct bulk band gap (SOC gap) depends on the strength of spin-orbit coupling (SOC) which is strain-dependent.

(E) In the absence of spin-orbit coupling, there are two line nodes on the k x mirror plane and two line nodes on the k y mirror plane (red loops). In the presence of spin-orbit coupling, each line node reduces into six Weyl nodes (small black and white circles). Black and white show the opposite chiral charges of the Weyl nodes.

The band inversion can be realized by increasing the spin-orbit coupling (SOC) of Sb by more than $30%$, and this results in a TPT from a trivial AFM insulator to an AFM topological insulator or an axion insulator. The compressive uniaxial strain can also drive a similar TPT if the interlayer distance is shortened by more than $5%$.

The ground-state phases of spin-1 Bose-Einstein condensates with SU(3) spin-orbit (SO) coupling in a rotating annular potential are studied.

When rotation is considered, we find coreless vortices and singular vortices can be generated simultaneously and.
