Partition Functions in Classical and Quantum Mechanics
... . Now that we have evaluated the partition function of the classical harmonic oscillator we now wish to evaluate the same quantity for the quantum harmonic oscillator. In other words, we wish to answer the question : ‘What is the canonical partition function if the mass attached to the spring obeys ...
