Ising gauge theory
WitrynaNow the critical theory has fractionalized excitations and a gapless gauge field. In the context of two-dimensional antiferromagnets with half-integer spin per unit cell, the effective description in terms of Ising gauge theories requires a background static electric charge on each site: this is the odd Ising gauge theory.

Witryna13 lut 1986 · We numerically study Ising gauge theories in non-integer dimensions below four dimensions using fractals. We find indications that the first-order transition of the d = 4 theory becomes second order for d = 4 − ϵ for arbitrarily small non-zero ϵ. This suggests that the upper critical dimension of abelian gauge theories is four. WitrynaWe compare the predictions of the effective string description of confinement with a set of Montecarlo data for the 3d gauge Ising model at finite temperature. Thanks to a new algorithm which makes use of the dual symmetry of the model we can reach very high precisions even for large quark-antiquark distances. We are thus able to explore the …
