Creation and control of valley currents in graphene by few cycle light pulses
In plane symmetry breaking by circularly polarized light
We consider a circularly polarized light pulse applied to a graphene system in which a small gap Δ has been imposed at the Dirac point. Such gaps can readily be introduced by the particular…

Unveiling hidden particle-level defects in glasses
We investigated the nature of mechanical defects in glasses using three distinct 2D model systems. The first two models are glasses: one uses an inverse power-law potential (2DIPL)39,40, which is purely repulsive, and the other employs the…

Experimental demonstration of high-speed continuous variable quantum key distribution enhanced by phase-sensitive amplifier
Working principle
The original GG02 protocol with homodyne detection can be phase-sensitively amplified but needs rapid basis switching for amplification, which requires rapid phase switching and locking of the PSA pump light. Alternatively, the…
