Название: New Two-Color Dimer Models with Critical Ground States
Авторы: Raghavan R., Henley C.
Аннотация:
We define two new models on the square lattice in which each allowed configuration is a superposition of a covering by "'white" dimers and one by "black" dimers. Each model maps to a solid-on-solid (SOS) model in which the "height" field is two dimensional.
