Phase Diagram of a Two-Dimensional Neutral Classical Coulomb Gas from a Non-perturbative sine-Gordon Expansion
Wen-Fa Lu, Chul Koo Kim
Within the sine-Gordon formalism of a two-dimensional neutral classical Coulomb gas, a convergent expansion with non-perturbative nature is performed to calculate the thermodynamic…
