Abstract: Abstract Viscoelasticity in metallic glasses (MGs) is commonly attributed to atomic slips or the activation of local shear transformation events. However, based on our extensive molecular dynamics simulations of creep in MGs, we find that… read more here.

Abstract: We observe effects of collective atomic motion in a one-dimensional optical lattice coupled to an optomechanical system. In this hybrid atom-optomechanical system, the lattice light generates a coupling between the lattice atoms as well as… read more here.
