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 …

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 …

Berry phase and Berry curvature have become ubiquitous concepts in physics, relevant to a
variety of phenomena, such as polarization, various Hall effects, etc. Studies of these …

Ultrafast extreme ultraviolet (XUV) transient absorption is the process by which atoms and
molecules absorb light on a timescale faster than the lifetime of the states involved …

Optical waveforms of light reproducible with subcycle precision underlie applications of
lasers in ultrafast spectroscopies, quantum control of matter and light-based signal …

Ultrafast extreme ultraviolet (XUV) transient absorption spectroscopy measures the time-and
frequency-dependent light losses after light–matter interactions. In the linear region, the …

Attosecond metrology with linearly polarized light pulses is the basis of a highly successful
research area. An even broader impact can be expected from a generalized metrology that …

The versatility of optical parametric amplifiers makes them excellent sources for ultrashort
visible and infrared pulses that drive strong-field physics experiments. We extend four-wave …

We experimentally investigate the manifestations of broken inversion symmetry in solids in
two-color interferometric measurements. Polarization-resolved, high-order harmonic spectra …

We theoretically investigate the quantum path interferences in interband transitions in solid
high-order harmonic generation. The field strength scaling of the 19th harmonic yield from …
