- Abstract
We generalize the well-known partition function of Fermi harmonic oscillator (formula available within PDF) (formula available within PDF) to (formula available within PDF) for Fermi system described by the n-mode fermionic Hamiltonian (formula available within PDF) . This result is derived via constructing the fermionic coherent state representation of the density operator (formula available within PDF) in which (formula available within PDF) is identified as exp{-βΓΠ}.
