High-harmonic generation in atomic gases has been studied for decades, and has formed
the basis of attosecond science. Observation of high-order harmonics from bulk crystals was …

The advent of visible-infrared laser pulses carrying a substantial fraction of their energy in a
single field oscillation cycle has opened a new era in the experimental investigation of …

High-harmonic generation in the two topological phases of a finite, one-dimensional,
periodic structure is investigated using a self-consistent time-dependent density functional …

High-harmonic generation in isolated atoms and molecules has been widely utilized in
extreme ultraviolet photonics and attosecond pulse metrology. Recently, high-harmonic …

Interaction of intense lasers with solid materials offers an alternative way to achieve high-
order harmonic generation (HHG). Since the underlying mechanisms of the harmonic …

Solid-state high-harmonic sources offer the possibility of compact, high-repetition-rate
attosecond light emitters. However, the time structure of high harmonics must be …

We explore pump-probe high harmonic generation (HHG) from monolayer hexagonal-boron-
nitride, where a terahertz pump excites coherent optical phonons that are subsequently …

We theoretically study high-order-harmonic generation (HHG) from solids driven by intense
laser pulses using a one-dimensional model periodic crystal. By numerically solving the time …

High harmonic generation in crystalline solids has been examined so far on the basis of one-
body energy-band structures arising from electron itineracy in a periodic potential. Here, we …

To study excitonic effects on high-harmonic generation (HHG) in Mott insulators, we
investigate pumped nonequilibrium dynamics in the one-dimensional extended Hubbard …
