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 …

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 …

The ability to steer electrons using the strong electromagnetic field of light has opened up
the possibility of controlling electron dynamics on the sub-femtosecond (less than 10− 15 …

Resolving the fundamental carrier dynamics induced in solids by strong electric fields is
essential for future applications, ranging from nanoscale transistors, to high-speed electro …

High-order harmonic spectra from solid materials driven by single-color multicycle laser
fields sometimes contain even harmonics. In this work we attribute the appearance of even …

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 …

In this work, the nonlinear optical response, and in particular, the high harmonic generation
of semiconductors, is addressed by using the Wannier gauge. One of the main problems in …

Cooper minimum structure of high-order harmonic spectra from atoms or molecules has
been extensively studied. In this paper, we demonstrate that the crystal harmonic spectra …

We introduce a quasi-classical model in the k space combined with the energy band
structure of solids to understand the mechanisms of high-order harmonic generation (HHG) …

Electronic coherence is of utmost importance for the access and control of quantum-
mechanical solid-state properties. Using a purely electronic observable, the photocurrent …
