What Happens to Energy When Phonons are Damped?

[QUOTE="hutchphd, post: 6503541, member: 635497"] If it isn't in the Hamiltonian, it doesn't exist. We are neglecting a host of things when writing the simple harmonic Hamiltonian. The ways we include them are various and depend upon what we need to calculate. Rigorously one includes them and shows which ones can be ignored or for a thermal reservoir which can be treated in an average (perhaps complex-valued) potential. The details depend upon how we convert the otherwise intractable problem into a useful solution. What you are asking in essence is "If we ignore all the other interactions then the energy loss will be due to "X"". The answer to that question is tautologically yes every time. [/QUOTE]
