Physics · Quantum Mechanics
Consider a quantum particle in a one-dimensional box of length L. The coordinate of the leftmost wall of the box is at x = 0 and that of the rightmost wall is at x = L. The particle is in the ground state at t = 0. At t = 0, we suddenly change the length of the box to 3L by moving the right wall. What is the probability that the particle is in the ground state of the new system immediately after the change?
