Nonperturbative Casimir effect of compact electrodynamics in 2+1 dimensions

We represent a brief result of Casimir effects in compact electrodynamics in two spatial dimensional systems by a nonperturbative approach. Basing a previous paper [3] which examined the Casimir effect between two ideal electric wires, we study the boundaries of the Casimir system under two cases: two wires are ideal magnetic conductors and a mixed system consists of an ideal electric conductor faced with one ideal magnetic one. Consequently, there is the existence of an attractive potential between two ideal magnetic wires meanwhile a repulsive force between mixed systems. We also estimate the contribution of monopole to Casimir energies for two cases to conclude that monopole lowers Casimir energies. Finally, we estimate the phase transition of monopoles to propose that there is an emergence of BKT phase transition from unbinding to binding phases of monopole-antimonopole at a small separation
