Critical exponent of quantum phase transitions driven by colored noise
D. Nagy, P. Domokos
We demonstrate that criticality in a driven-dissipative system is strongly influenced by the spectral properties of the reservoir. We study the open-system realization of the Dicke…
Observation of the photon-blockade breakdown phase transition
J. M. Fink, A. Dombi, A. Vukics +2
Non-equilibrium phase transitions exist in damped-driven open quantum systems, when the continuous tuning of an external parameter leads to a transition between two robust steady s…
Magnetic noise spectrum measurement by an atom laser in gravity
O. Kálmán, Z. Darázs, F. Brennecke +1
Bose-Einstein condensates of ultracold atoms can be used to sense fluctuations of the magnetic field by means of transitions into untrapped hyperfine states. It has been shown rece…
Depolarization shift of the superradiant phase transition
Tobias Grießer, András Vukics, Peter Domokos
We investigate the possibility of a Dicke-type superradiant phase transition of an atomic gas with an extended model which takes into account the short-range depolarizing interacti…
