Collective modes and superfluidity of a two-dimensional ultracold Bose gas
The collective modes of a quantum liquid shape and impact its properties profoundly, including its emergent phenomena such as superfluidity. Here we present how a two-dimensional Bose gas responds to a moving lattice potential. In particular, we discuss how the induced heating rate depends on the in...
