Quantum critical states and phase transitions in the presence of non equilibrium noise

Understand

Quantum critical points are characterized by scale invariant correlations and correspondingly long ranged entanglement.

• As such, they present fascinating examples of quantum states of matter, the study of which has been an important theme in modern physics.
• Nevertheless very little is known about the fate of quantum criticality under non equilibrium conditions.
• In this paper we investigate the effect of external noise sources on quantum critical points.
