Superfluidity: Quantum Mechanics on Big Scale
Prof. Lev P. Pitaevskii
INO-CNR BEC Center and Dip. Fisica, Trento
& Kapitza Institute for Physical Problems, Moscow
ABSTRACT:
Superfluidity is a quantum phenomenon which takes place in liquid helium
at low temperature and in ultracold gases in traps. The lecture is devoted
to peculiar features of these systems, where the specific quantum
mechanical properties, whose description involves the quantum Planck
constant, cam be observed in macroscopic experiments. The quantum
vortices, in rotating superfluid, the classical limit of the de Broglie
waves and the “two-fluid” phenomena will be discussed at elementary level.
