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 …

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 …

In strong-field physics and attosecond science, intense light induces ultrafast electron
dynamics. Such ultrafast dynamics of electrons in matter is at the core of phenomena such …

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 …

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

The last few decades have witnessed the extraordinary advances in theoretical and
experimental tools, which have enabled the manipulation and monitoring of ultrafast …

The semiconductor Bloch equations (SBEs) are routinely used for simulations of strong-field
laser-matter interactions in condensed matter. In systems without inversion or time-reversal …

Under strong laser fields, electrons in solids radiate high-harmonic fields by travelling
through quantum pathways in Bloch bands in the sub-laser-cycle timescales. Understanding …

Under strong electromagnetic excitation, electron–hole (eh) pairs may be generated in
solids, which are subsequently driven to high energy and high momentum, producing high …

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 …
