Yang–Mills, Aharonov–Bohm, Aharonov–Casher, and the Berry–Pancharatnam effects …

Topological resonance and single-optical-cycle valley polarization in gapped graphene

SA Oliaei Motlagh, F Nematollahi, V Apalkov… - Physical Review B, 2019 - APS
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 …

Dynamical birefringence: electron-hole recollisions as probes of Berry curvature

HB Banks, Q Wu, DC Valovcin, S Mack, AC Gossard… - Physical Review X, 2017 - APS
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 …

Femtosecond valley polarization and topological resonances in transition metal dichalcogenides

SA Oliaei Motlagh, JS Wu, V Apalkov, MI Stockman - Physical Review B, 2018 - APS
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) …

Second-harmonic generation in noncentrosymmetric phosphates
