Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" ...

Recent physics studies have found that light can sometimes flow in unexpected ways, behaving like a so-called "superfluid." ...

Space-time wave packets are a class of pulsed beams whose distinguishing characteristic is that they are endowed with precise spatio-temporal structure. Here we present recent results with space-time ...
