  • We introduce strong tailored light-wave-driven time-reversal symmetry breaking in monolayer hexagonal boron nitride, realizing a sub-laser-cycle controllable analogue of the topological model of Haldane and inducing non-resonant valley polarization.

  • The H3+ ion plays a key role in interstellar chemistry and can be formed from organic compounds upon interaction with charged particles or radiation. Here the authors demonstrate that H3+ can also be formed from water adsorbed on silica nanoparticles exposed to intense laser pulses, conditions that mimic the impact of charged particles on dust in astrophysical settings.

  • Understanding light-matter interaction is important for the control of energy and charge transfer at the fundamental level. Here the authors spatially resolve proton generation in laser-induced dissociative ionization of ethanol and water on SiO2 nanoparticles and discuss the role of surface charge distribution.
