In quantum mechanics, the Kramers' degeneracy theorem states that for every energy eigenstate of a time-reversal symmetric system with half-integer total spin, there is another eigenstate with the same energy related by time-reversal. In other words, the degeneracy of every energy level is an even number if it has half-integer spin.

WebJan 30, 2024 · The degeneracy of the ground state is \(2I+1\). The application of a magnetic field splits the degenerate 2I+1 nuclear energy levels.

Let us, rather naively, investigate the Stark effect in an excited ( i.e., n > 1) state of the hydrogen atom using standard non-degenerate perturbation theory. We can write H0ψnlm = Enψnlm, because the energy eigenstates of the unperturbed Hamiltonian only depend on the quantum number n.

WebWe present an effective theory for the Bloch functions of a two-dimensional square lattice near a quadratic degeneracy point. The degeneracy is protected by the symmetries of the crystal, and breaking these symmetries can either open a band gap or split the degeneracy into a pair of linear degeneracies that are continuable to Dirac points.
