The conceptual power of the Hellmann–Feynman theorem

In quantum mechanics, the Hellmann–Feynman theorem relates the derivative of the total energy with respect to a parameter, to the expectation value of the derivative of the Hamiltonian with respect to that same parameter. According to the theorem, once the spatial distribution of the electrons has been determined by solving the Schrödinger equation, all the forces in the system can be calculated using classical electrostatics. Web1 dag geleden · By Joel Hellman and Daniel Kaufmann - I only want to draw your attention straightaway to the fact that you have yourselves formed this very state, to a large extent through political and quasi-political structures under your control.
