Self-Duality and Phase Structure of the 4D Random-Plaquette Z_2 Gauge Model
Gaku Arakawa, Ikuo Ichinose, Tetsuo Matsui +1
In the present paper, we shall study the 4-dimensional Z_2 lattice gauge model with a random gauge coupling; the random-plaquette gauge model(RPGM). The random gauge coupling at ea…

Self-dual random-plaquette gauge model and the quantum toric code
Koujin Takeda, Hidetoshi Nishimori
We study the four-dimensional Z_2 random-plaquette lattice gauge theory as a model of topological quantum memory, the toric code in particular. In this model, the procedure of quan…
