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 …

In quantum materials, emergent functional properties resulting from strong correlations or
electronic topology offer opportunities for new applications. Over the past decade, ultrafast …

Intense light–matter interactions have revolutionized our ability to probe and manipulate
quantum systems at sub-femtosecond timescales, opening routes to the all-optical control of …

Since 2001 and the first demonstrations of the feasibility of generating and measuring
attosecond light pulses, attosecond science has developed into a very active and quickly …

High harmonic generation (HHG) is usually described by the laser-induced recollision of
particlelike electrons, which lies at the heart of attosecond physics and also inspires …

We study theoretically nonlinear optical properties of graphene quantum dots placed in a
field of a short and strong linearly polarized optical pulse. We address the problem of high …

Field-induced tunneling is one of the most fundamental quantum phenomena. In atoms this
process has been successfully explored by attosecond interferometry based on high …

Many-body entanglement in condensed matter systems can be diagnosed from equilibrium
response functions through the use of entanglement witnesses and operator-specific …

High harmonic generation (HHG) in crystals has revealed a wealth of perspectives such as
all-optical map** of the electronic band structure, ultrafast quantum information, and the …

There is a need for a universal model to describe higher harmonic generation (HHG) in
different states of matter. Based on an electromagnetic model (EM), the generation of odd …
