DOI: 10.1038/d41586-018-07851-7
Abstract: In materials called Weyl semimetals, electrons form structures that have distinct topological properties. The discovery of an ultrafast switch between two of these structures could have many practical applications.Ultrafast manipulation of a topological material. read more here.

DOI: 10.1103/physrevb.97.085419
Abstract: We demonstrate that plasmons in graphene can be manipulated using a dc current. A source-drain current lifts the forward/backward degeneracy of the plasmons, creating two modes with different propagation properties parallel and antiparallel to the… read more here.

DOI: 10.1103/physrevlett.119.123603
Abstract: We realize a phase-sensitive closed-loop control scheme to engineer the fluctuations of the pump field which drives an optomechanical system and show that the corresponding cooling dynamics can be significantly improved. In particular, operating in… read more here.

DOI: 10.1364/ol.43.003401
Abstract: We report for the first time on-chip integration of III-nitride voltage-controlled light emitters with visible and ultraviolet (UV) photodiodes (PDs). InGaN/GaN and AlGaN/GaN heterostructures were grown in specific regions by selective-area epitaxy, allowing monolithic integration… read more here.

DOI: 10.3390/polym9060241
Abstract: Detection of defects, damages and cracks in structural polymers is very difficult, and even if they are detected, they will be very hard to be repaired. This is because different kinds of stress can reduce… read more here.
