Generalized Virial Theorem for Mixed State When Hamiltonians Include Coordinate-Momentum Couplings

Wang Min

Published May 1, 2008• 4 citations
Publisher

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.

Deriving Internal Energy by Virtue of Generalized Feynman–Hellmann Theorem for Mixed States

Hong-Yi Fan, Zhonghua Jiang

We show how to directly use the generalized Feynman–Hellmann theorem, which is suitable for mixed state ensemble average, to derive the internal energy of Hamiltonian systems. A concrete example, which is a two coupled harminic oscillators, is used for elucidating our approach.

An elementary derivation of the quantum virial theorem from Hellmann–Feynman theorem

Y. İpekoğlu, S. Turgut

Abstract A simple proof of the quantum virial theorem that can be used in undergraduate courses is given. The proof proceeds by first showing that the energy eigenvalues of a Hamiltonian remain invariant under a scale transformation. Then invoking the Hellmann–Feynman theorem produces the final statement of the virial theorem.

Proof of the quantum virial theorem

Zhu Dongpei

Based on the Feynman–Hellmann theorem, a new proof of the quantum virial theorem is presented. The same approach is also used to derive the virial formulation in relativistic quantum mechanics and for the case where the vector potential exists.

Application of generalized Hellmann-Feynman theorem in deriving internal energy of some Hamiltonians in quantum optics

Hong-Yi Fan, Min Wang, Peng Yan

In this paper, after introducing the generalized Hellmann-Feynman (or Feynman-Hellmann) theorem (GHFT) for mixed-state ensemble average, we apply GHFT to deriving the internal energy of some Hamiltonian systems in quantum optics. The ensemble average energy contributed from each separated term involved in the Hamiltonian is also considered. We thus develop an alternate approach for deriving the internal energy.
