Floquet-Weyl semimetals (FWSMs) generated by irradiation of a continuous-wave laser with left-hand circular polarization (rotating in counterclockwise sense with time) on the group II-V narrow gap semiconductor Zn 3 As 2 are theoretically investigated, where the frequency of the laser is set nearly resonant with a band gap of the crystal. It is found that the excitation of the crystal by such a laser induce two types of FWSM phases that differ absolutely in characters. To be specific, the…

Topological invariants for anomalous Floquet higher-order topological insulators

We review the recent development in constructing higher-order topological band insulators under strong periodic drivings. In particular, we focus on various approaches in formulating the anomalous



Nonequilibrium hybrid multi-Weyl semimetal phases

Multi-Weyl semimetals are variations of Weyl semimetals characterized by isolated band touching points, each carrying multiple topological charges. Given a plethora of exotic transport properties

Edge states of Floquet–Dirac semimetal in a laser-driven semiconductor quantum-well

Band crossings observed in a wide range of condensed matter systems are recognized as a key to understand low-energy fermionic excitations that behave as massless Dirac particles. Despite rapid

The 3D analogue of graphene is known as Weyl semimetal, where the excitations energy is a linear function of their momentum. Floquet theory is an alternative way of study of conventional Rabi

Surface plasmon polaritons in a topological insulator embedded in an optical cavity

Very recently, the surface plasmons in a topological insulator (TI) have been experimentally observed by exciting these collective modes with polarized light [P. Di Pietro, M. Ortolani, O. Limaj, A.
