The nonlinear optical and optoelectronic properties of graphene with the emphasis on the
processes of harmonic generation, frequency mixing, photon drag and photogalvanic effects …

The diverse applications of terahertz (THz) radiation and its importance to fundamental
science makes finding ways to generate, manipulate and detect THz radiation one of the key …

Applications that use the orbital angular momentum (OAM) of light show promise for
increasing the bandwidth of optical communication networks. However, direct photocurrent …

We construct a systematic high-frequency expansion for periodically driven quantum
systems based on the Brillouin-Wigner (BW) perturbation theory, which generates an …

In the presence of a circularly polarized mid-infrared radiation graphene develops
dynamical band gaps in its quasienergy band structure and becomes a Floquet insulator …

Graphene irradiated by a circularly polarized laser has been predicted to be a Floquet
topological insulator showing a laser-induced quantum Hall effect. A circularly polarized …

Weyl semimetals (WSMs) are gapless topological states of matter with broken inversion
and/or time reversal symmetry. WSMs can support a circulating photocurrent when …

The paper reviews the interplay of Rashba/Dresselhaus spin splittings in various two‐
dimensional systems made of zinc‐blende III–V, wurtzite, and SiGe semiconductors. We …

Elemental tellurium, conventionally recognized as a narrow bandgap semiconductor, has
recently aroused research interests for exploiting Weyl physics. Chirality is a unique feature …

Motivated by recent pump-probe spectroscopies, we study the effect of phonon dissipation
and potential cooling on the nonequilibrium distribution function in a Floquet topological …
