Generalized Virial Theorem for Mixed State When Hamiltonians Include Coordinate-Momentum Couplings
Wang Min
Abstract
The generalized Virial theorem for mixed state, derived from the generalized Hellmann–Feynman theorem, only applies to Hamiltonians in which potential of coordinates is separate from momentum energy term. In this paper we discuss Virial theorem for mixed state for some Hamiltonians with coordinate-momentum couplings in order to know their contributions to internal energy.
