Coherence, Broken Symmetry and Nondissipative Motion of a Quantum Oscillator
Abstract
Using the example of a quantum oscillator, the connection between the dynamical coherent state with the phase symmetry breaking and the existence of the non-dissipative motion is considered. In multiparticle systems of interacting particles similar states manifest themselves as superfluidity and superconductivity.
