On the Extensions of Virial and Feynman - Hellman Theorem
Abstract: In the present work off diagonal and higher order extensions of Feynman-Hellman theorem is studied Rayleigh-Schrodinger perturbation theory for the degenerate case is redefined using a new technique. We also consider off-diagonal extension of quantum mechanical virial theorem by considering the case of linear harmonic oscillator.
Keywords: Rayleigh-Schrodinger perturbation theory, Feynman-Hellman theorem, quantum mechanical virial theorem, linear harmonic oscillator
