The derivative of an eigenvalue of this thing with respect to a parameter is equal to the expectation valueof the derivative of this thing with respect to that parameter according to a theorem named for Hellman andFeynman.
The derivative of an eigenvalue of this thing with respect to a parameter is equal to the expectation valueof the derivative of this thing with respect to that parameter according to a theorem named for Hellman andFeynman. The RAGE theorem allows one to relate dynamical properties of states to the spectral propertiesof this thing. The von Neumann equation contains a term for the commutator of this thing and the densityoperator, which describes the time-dependence of the latter. This operator is a sum of two terms, one ofwhich is negative h-bar squared over two m times the Laplacian. E times a wave function is set equal to thisoperator of that wave function in the time-independent SchrÃ¶dinger equation. For 10 points, identify thisoperator that is equal to the sum of the kinetic and potential energy operators.
