Properties of solutions by the Schwinger-Dyson equation at finite temperature and density : A four-fermion interaction model
Hidekazu Tanaka, Shuji Sasagawa
In this paper, we examine the properties of the solutions obtained by the Schwinger-Dyson equation (SDE). As a simple example, we consider a two-dimensional model including four-fe…
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…
The separation of the chiral and deconfinement phase transitions in the curved space-time
S. Sasagawa, H. Tanaka
We calculated the chiral condensate and the dressed Polyakov loop in the space-time and . The chiral condensate is the order parameter for the chiral…
The effect of an imaginary part of the Schwinger-Dyson equation at finite temperature and density
S. Sasagawa, H. Tanaka
We examined the effect of an imaginary part of the ladder approximation Schwinger-Dyson equation. We show the imaginary part enhances the effect of the first order transition, and…
