Phase Structure of Thermal QED Based on the Hard Thermal Loop Improved Ladder Dyson-Schwinger Equation --a "Gauge Invariant" Solution--
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 satisfies the Ward identity. Properties of
the ``gauge-invariant'' solutions are discussed.Comment: 3figures, Proceedins of SCGT06 (Nagoya University, Japan, November
