Spontaneous Disentanglement and Thermalisation

Authors: Eyal Buks

The problem of quantum measurement can be partially resolved by incorporatinga process of spontaneous disentanglement into quantum dynamics. We propose amodified master equation, which contains a nonlinear term giving rise to bothspontaneous disentanglement and thermalisation. We find that the addednonlinear term enables limit cycle steady states, which are prohibited instandard quantum mechanics. This finding suggests that an experimentalobservation of such a limit cycle steady state can provide an importantevidence supporting the spontaneous disentanglement hypothesis.
