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 …

When intense lightwaves accelerate electrons through a solid, the emerging high-order
harmonic (HH) radiation offers key insights into the material,,,,,,,,,–. Sub-optical-cycle …

Strong light fields have created opportunities to tailor novel functionalities of solids,,,–.

Electrons in two-dimensional hexagonal materials have an extra degree of freedom, the
valley pseudospin, that can be used to encode and process quantum information. Valley …

Since the first observation of odd and even high-order harmonics generated from ZnO
crystals in 2011, the dependence of the harmonic yields on the orientation of the laser …

The sub-cycle interaction of light and matter is one of the key frontiers of inquiry made
