Universal decoherence induced by an environmental quantum phase transition

Mostrar todas las versiones(2)

Decoherence induced by coupling a system with an environment may display universal features. We demonstrate that when the coupling to the system drives a quantum phase transition in the environment, the decay of quantum coherences in the system is Gaussian with a width independent of the system-envi...
