Schwinger-Dyson equation on the complex plane -- A four-fermion interaction model at finite temperature --
Hidekazu Tanaka, Shuji Sasagawa
We extend the Schwinger-Dyson equation (SDE) on the complex plane, which was treated in our previous research, to finite temperature. As a simple example, we solve the SDE for a mo…

Schwinger-Dyson equation in the complex plane -- Two simple models --
Hidekazu Tanaka, Shuji Sasagawa
Effective mass and energy are investigated using the Schwinger-Dyson equation (SDE) in the complex plane. As simple examples, we solve the SDE for the (1+1)-dimensional model and t…
