1 Bohr-Sommerfeld Quantization
... These plane waves are simultaneous eigenfunctions of the Hamiltonian, H = p2 /2m, and the momentum operator, p = (h/i)∂/∂x. This is possible because [H, p] = 0. The energy eigenvalues of the plane wave states are doubly degenerate: Ep = E−p . By labeling a state according to its momentum quantum num ...

Quantum Degeneracy in Two Dimensional Systems
... non-degenerate state carries no current and is describable by a real valued wave function. This implies that wave functions for real Hamiltonian carrying current are degenerate. As a simple example, the ground state of the hydrogen atom is real and non-degenerate and does not carry any current. Howe ...
