Quantum Weak Invariants: Dynamical Evolution of Fluctuations and Correlations
Weak invariants are time-dependent observables with conserved expectation values. Their fluctuations, however, do not remain constant in time. On the assumption that time evolution of the state of an open quantum system is given in terms of a completely positive map, the fluctuations monotonically g...
