Phase Structure of Thermal QED Based on the Hard Thermal Loop Improved Ladder Dyson-Schwinger Equation --a "Gauge Invariant" Solution--

Hisao Nakkagawa, Hiroshi Yokota, Koji Yoshida

Based on the hard-thermal-loop resummed improved ladder Dyson-Schwinger quation for the fermion mass function, we study how we can get the gauge invariant solution in the sense it…
