WitrynaIn other words, we find that the Green’s function G(x;x 0) formally satisfies L xG(x;x 0) = (x x 0) (7) (the subscript on Lis needed since the linear operator acts on x, not x 0). This equation says that G(x;x 0) is the influence felt at x due to a point source at x 0. WitrynaProblems 1. A particle of mass m moves in a one-dimensional box of length L, with boundaries at x = 0 and x = L. Thus, V(x) = 0 for 0 ≤ x ≤ L, and V(x) = ∞ elsewhere. The normalized eigenfunctions of the Hamiltonian for this system are given by Ψn(x) = 2 L 1/2 Sin nπ x L , with En= n2π2h−2 2mL2

Suppose we have an insulated wire, and we apply constant temperature T1 at one end (say where x = 0) and T2 on the other end (at x = L where L is the length of the wire). Then our steady state solution is u(x) = T2 − T1 L x + T1.
