Superfluid and excitonic states

Part of the Lecture Notes in Physics book series (LNP, volume 57)


The fundamental difference between DLRO and ODLRO in relation to superfluidity is demonstrated by comparing the pseudospin model of Frenkel excitons with the quantum lattice model of 4He and assuming Bose condensation in both models. The argument is extended also to Wannier excitons.
