Generalization of the Hellmann-Feynman theorem
arXiv:0912.4153 · doi:10.1016/j.physleta.2009.12.005
Abstract
The well known Hellmann-Feynman theorem of Quantum Mechanics connected with the derivative of the eigenvalues with respect to a parameter upon which the Hamiltonian depends, is generalized to include cases in which the domain of definition of the Hamiltonian of the system also depends on that parameter.
