Dynamics of quantum phase transitions in Dicke and Lipkin-Meshkov-Glick models
A. P. Itin, P. Törmä
We consider dynamics of Dicke models, with and without counterrotating terms, under slow variations of parameters which drive the system through a quantum phase transition. The mod…

Laser probing of atomic Cooper pairs
P. Torma, P. Zoller
We consider a gas of attractively interacting cold Fermionic atoms which are manipulated by laser light. The laser induces a transition from an internal state with large negative s…
