High-harmonic spectroscopy of mobility edges in one-dimensional quasicrystals
H. K. Avetissian, B. R. Avchyan, A. Brown +1
Quasicrystals occupy a unique position between periodic and disordered systems, where localization phenomena such as Anderson transitions and mobility edges can emerge even in the…
Zeptosecond Electron Pulse Train and Ultrafast Coherent Control of Quantum States via Multiphoton Inelastic Cherenkov Diffraction
H. K. Avetissian, G. F. Mkrtchian
We investigate the quantum dynamics of fermionic particles interacting with a laser field in a gaseous medium, in the regime of inelastic diffraction scattering on the phase lattic…
Berry curvature and shift vector effects at high-order wave mixing in biased bilayer graphene
