Hierarchy Bloch Equations for the Reduced Statistical Density Operators in Canonical and Grand canonical Ensembles
Liqiang Wei, Chiachung Sun
Starting from Bloch equation for a canonical ensemble, we deduce a set of hierarchy equations for the reduced statistical density operator for an identical many-body system with tw…
