Thermal Operator Representation of Feynman Graphs
In this talk I describe an interesting relation between Feynman graphs at finite temperature and chemicalpotential and the corresponding ones at zero temperature. The operator relating the two which we call thethermal operator, simplifies the evaluation of finite temperature graphs and helps in un...
