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 …

Modern light generation technology offers extraordinary capabilities for sculpting light
pulses, with full control over individual electric field oscillations within each laser cycle …

The sub-laser-cycle timescale of the electronic response to strong fields enables attosecond
dynamical imaging in atoms, molecules and solids,,–, with optical tunnelling and high …

Strong-field-driven electric currents in condensed-matter systems are opening new frontiers
in petahertz electronics. In this regime, new challenges are arising as the roles of band …

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

Topological materials are of interest to both fundamental science and advanced
technologies because topological states are robust with respect to perturbations and …

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 …

We establish time-resolved high harmonic generation (tr-HHG) as a powerful spectroscopy
method for tracking photoinduced dynamics in strongly correlated materials through a …

Excitons play a key role in the linear optical response of two-dimensional (2D) materials.
However, their role in the nonlinear response to intense, nonresonant, low-frequency light is …
