The present status and development of strong-field nano-optics, an emerging field of
nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is …

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 …

Mechanisms of high-harmonic generation from crystals are described by treating the electric
field of a laser as a quasistatic strong field. Under the quasistatic electric field, electrons in …

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

Petahertz, or lightwave, electronics uses tailored optical waveforms to control charge
carriers in an electronic circuit at petahertz frequencies. This may enable faster processing …

We theoretically investigate the generation of ultrafast currents in insulators induced by
strong few-cycle laser pulses. Ab initio simulations based on time-dependent density …

Attoscience is the emerging field that accesses the fastest electronic processes occurring at
the atomic and molecular length scales with attosecond (1 as= 1 0− 18 s) time resolution …

Intense lasers can easily drive nonadiabatic transitions of excited electron wave packets
across the Brillouin zones, thus transition dipole moments (TDM) between energy bands of …

Attosecond science relies on the use of intense, waveform-controlled, few-cycle laser pulses
to control extreme nonlinear optical processes taking place within a fraction of an optical …
