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 …

Key properties of quantum materials stem from dynamic interaction chains that connect
stable electronic quasiparticles through short-lived coherences, which are difficult to control …

High-harmonic generation (HHG) in solids has emerged in recent years as a rapidly
expanding and interdisciplinary field, attracting attention from both the condensed-matter …

We reveal the crucial effect of strong spin-charge coupling on high-harmonic generation
(HHG) in Mott insulators. In a system with antiferromagnetic correlations, the HHG signal is …

High harmonic generation (HHG) from gas-phase atoms (or molecules) has opened up a
new frontier in ultrafast optics, where attosecond time resolution and angstrom spatial …

We theoretically investigate high harmonic generation (HHG) from silicon thin films with
thicknesses from a few atomic layers to a few hundreds of nanometers, to determine the …

By numerically solving the semiconductor Bloch equation, we study the high-order harmonic
emission spectrum of a MgO crystal under the interaction of a linearly polarized laser pulse …

We develop and demonstrate a fully real-space perspective on high harmonic generation
(HHG) in crystals. Due to the Wannier-Stark localization induced on subcycle timescales in …

We propose a novel approach based on the subcycle injection of carriers to extend the high-
energy cutoff in solid-state high harmonics. The mechanism is first examined by employing …

The issue of quantum dephasing in solids subjected to strong, off-resonant excitation
continues to challenge our current understanding of nonperturbative extreme nonlinear …
