We investigate theoretically the strong-field regime of light-matter interactions in the
topological-insulator class of quantum materials. In particular, we focus on the process of …

We review briefly the origin of gauge physics as well as their modern manifestations eg in
Yang–Mills, Aharonov–Bohm, Aharonov–Casher, and the Berry–Pancharatnam effects …

For gapped graphene, we predict that an intense ultrashort (single-oscillation) circularly
polarized optical pulse can induce a large population of the conduction band and a large …

The direct measurement of Berry phases is still a great challenge in condensed-matter
systems. The bottleneck has been the ability to adiabatically drive an electron coherently …

We theoretically introduce the fundamentally fastest induction of a significant population and
valley polarization in a monolayer of a transition metal dichalcogenide (ie, MoS 2 and WS 2) …

Motivated by the discovery of more and more phosphates with relatively strong nonlinear
optic effect, we studied the mechanism of the second-harmonic generation (SHG) effect in …

We theoretically study the interaction of ultrashort optical pulses with gapped graphene.
Such a strong pulse results in a finite conduction band population and a corresponding …

The electronic structure, nonlinear electronic polarization induced by a static external
electric field, and frequency dependent second-harmonic susceptibility tensor of the …

Coherent time is a characteristic time in the extreme nonlinear optics regime and thus
generally introduced as the dephasing time in simulations of solid-state high-harmonic …

The chemical-electronic structures of functional modules and their spatial arrangement
mainly determine the functional performance of materials. Tetrahedral structural units in …
