Imaging nonequilibrium phonons
Phonons are ubiquitous in condensed matter, but detecting them can be difficult—especially with the momentum and time resolution necessary to follow their dynamics on the fundamental time and length scales of electron-phonon and phonon-phonon interactions. In a new paper published this week in Physical Review B, physicists from the Stanford PULSE Institute report on first [...]

Intense laser-matter interactions results in high-order harmonic generation in solids
Harmonic generation (HHG) is a general feature of driven nonlinear systems and is well known to occur for strong field laser interactions with atomic systems. This is the basis for producing attosecond pulses in the VUV. The mechanism is well understood in terms of a simple three step model consisting of strong-field ionization, acceleration of [...]
