Uncertainty product of an out-of-equilibrium many-particle system
Uncertainty product of an out-of-equilibrium many-particle system
The variance of a many-particle operator is a very sensitive probe of many-body correlations. In contrast to the expectation value of such operators which depends on the condensation fraction of the Bose-Einstein condensate (BEC), their variance depends on the absolute number of depleted particles. Consequentially, the many-body correlations incorporated within …
