Semiclassical Correlation in Density
... Problem!! The KS state remains doubly-occupied throughout – cannot evolve into a singly-excited KS state under any one-body Hamiltonian. -- Exact KS system achieves the target excited-state density, but with a doublyoccupied ground-state orbital !! -- Exact vxc (t) is unnatural and difficult to appr ...

... The optimal error probability of discriminating two quantum states ρ0 and ρ1 has been identified a long time ago by Helström [3]. We consider the two hypotheses H0 and H1 that a given quantum system is prepared either in the state ρ0 or in the state ρ1 , respectively. Since the (quantum) Chernoff b ...
