Generalisation of the Hellmann-Feynman theorem to Gamow states

Abstract

The Hellmann-Feynman theorem valid for the parameter dependence of bound states is generalised to the case of Gamow states using an appropriate definition of scalar products and expectation values with such states. The one-dimensional square well potential is considered as an illustrative example.

The Hellmann–Feynman theorem at finite temperature

Marina Pons, Bruno Juliá-Díaz, Artur Polls +2 more

We present a simple derivation of the Hellmann–Feynman theorem at finite temperature. We illustrate its validity by considering three relevant examples, which can be used in quantum mechanics lectures: the one-dimensional harmonic oscillator, the one-dimensional Ising model, and the Lipkin model. We show that the Hellmann–Feynman theorem allows one to calculate expectation values of operators that appear in the Hamiltonian. This is particularly useful when the total free energy is available, but there is no direct access to the thermal average of the operators themselves.

The Hellmann–Feynman theorem, the comparison theorem, and the envelope theory

Claude Semay

The envelope theory is a convenient method to compute approximate solutions for bound state equations in quantum mechanics. It is shown that these approximate solutions obey a kind of Hellmann–Feynman theorem, and that the comparison theorem can be applied to these approximate solutions for two ordered Hamiltonians.

Hellmann-Feynman Theorems in Classical and Quantum Mechanics

William A. McKinley

Theorems giving exact expressions for the derivative of the energy with respect to a parameter in the Hamiltonian for cyclic classical mechanical problems in both the relativistic and nonrelativistic cases are derived. Comparison is made with similar well-known theorems in the quantum mechanical case. Applications of both classical and quantum derivative relations are made to deduction of parametric dependence of the energy in simple cases, deduction of a meaning to the expectation value of the Dirac operator β, and construction of a test of consistency for a well posed problem in the theory of a Dirac particle in a bound state.

Diagrammatic analysis of the Hellmann-Feynman theorem: Numerical applications

R. Sartor

Various versions of the Hellmann-Feynman theorem that were studied in a previous paper are applied to the actual computation of certain contributions to the expectation value of the kinetic and potential energies of nuclear matter. The numerical importance of the contributions which violate the Bethe-Brandow-Petscheck theorem in some versions is examined. We also provide a discussion of the so-called conserving approximation which directly derives the expectation value of the kinetic energy from that of the potential energy.

Hellmann–Feynman theorem in a linear superposition of energy eigenstates

A generalization to the Hellmann–Feynman theorem is presented when the quantum mechanical state is a linear superposition of energy eigenstates. Some simple applications are discussed.
