Forward scattering amplitudes and the thermal operator representation
Fernando T. Brandt, Ashok Das, Josif Frenkel +1
We develop systematically to all orders the forward scattering description for retarded amplitudes in field theories at zero temperature. Subsequently, through the application of t…

Thermal Operator and Cutting Rules at Finite Temperature and Chemical Potential
F. T. Brandt, Ashok Das, Olivier Espinosa +2
In the context of scalar field theories, both real and complex, we derive the cutting description at finite temperature (with zero/finite chemical potential) from the cutting rules…
