WebAug 7, 2024 · I’ll do two examples by hamiltonian methods – the simple harmonic oscillator and the soap slithering in a conical basin. Both are conservative systems, and we can write the hamiltonian as T + V, but we need to remember that we are regarding … WebAug 15, 2024 · The Hamiltonian operator is a quantum mechanical operator with energy as eigenvalues. It corresponds to the total energy inside a system including kinetic and potential energy. The eigenvalues of this operator are, in fact, the possible outcomes of the total energy of a quantum mechanical system.
