Consider a simple harmonic oscillator of angular frequency w. You are given that it's average energy is <H>=E.
a.Use the maximization of the entropy in order to calculate its density matrix in the energy representation.Express the inverse temperature β=1/(KbT) in terms of E and w.
b. Is this oscillator in a pure or in a mixed state?why?
