Free Fermions at Finite Temperature : An Application of the Non-Commutative Algebra


Charret et. al. applied the properties of the Grassmann generators to develop a new method to calculate the coefficientes of the high temperature expansion of the grand canonical partition function of self-interacting fermionic models in any d-dimensions (d ≥ 1). The method explores the anti-commuting nature of fermionic fields and avoids the calculation of… (More)
