When solids are exposed to intense laser fields whose forces are comparable to the binding
forces of valence electrons in crystals, nonlinear optics of solids advances to the …

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 …

Since high-order harmonic generation (HHG) from atoms depends sensitively on the
polarization of the driving laser field, the polarization gating (PG) technique was developed …

Strongly driven systems of emitters offer an attractive source of light over broad spectral
ranges up to the X-ray region. A key limitation of these systems is that the light they emit is …

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 …

Engineering effective electronic parameters is a major focus in condensed matter physics.
Their dynamical modulation opens the possibility of creating and controlling physical …

We theoretically investigate high-harmonic generation in hexagonal boron nitride with
linearly polarized laser pulses. We show that imperfect recollisions between electron-hole …

High harmonic generation (HHG) is an extremely nonlinear effect generating coherent
broadband radiation and pulse durations reaching attosecond timescales. Conventional …

Using Floquet dynamical mean-field theory, we study the high-harmonic generation in the
time-periodic steady states of wide-gap Mott insulators under ac driving. In the strong-field …

We revisit the mechanism of high-harmonic generation (HHG) from solids by comparing
HHG in laser fields with different ellipticities but a constant maximum amplitude. It is shown …
