Question

Does this Hamiltonian have point spectrum?

Answer 1

Explanation:

As always for an equation of motion, one has to provide an initial state (starting point) i.e., the wave function for t = 0.

Answer 2

Explanation:

• Consider such a Hamiltonian

H=−1/2-∂2/∂x2−Fx+V(x),

with F being some constant, and V(x)=V(x+L) being some periodic potential.
