Probing topological phase transitions in Aubry-Andre-Harper model via high-harmonic generation
Nivash R, Jayendra N. Bandyopadhyay, Amol R. Holkundkar
We study the high-harmonic generation in the Aubry-Andre-Harper (AAH) model. The modulating phase of the AAH model is used as a control parameter while preserving the chiral symmet…

Role of inter- and intraband current in laser interaction with bi-chromatic quasi-periodic crystals
Amol R. Holkundkar, Nivash R, Jayendra N. Bandyopadhyay
We study the role of the inter- and intraband current in the laser interaction with the bi-chromatic quasi-periodic crystals. The interaction dynamics are simulated by solving the…

Temporal control of high-order harmonic cutoffs in periodic crystals
Nivash R., Amol R Holkundkar, Jayendra N. Bandyopadhyay
A theoretical study on the high-harmonic generation (HHG) in solids by a synthesized driver field is carried out. The vector potential of the driver field is instrumental in determ…
