متن کاملCriticality of a classical dimer model on the triangular lattice.
We consider a classical interacting dimer model which interpolates between the square lattice case and the triangular lattice case by tuning a chemical potential in the diagonal bonds. The interaction energy simply corresponds to the number of plaquettes with parallel dimers. Using transfer matrix calculations, we find in the anisotropic triangular case a succession of different physical phases...
متن کاملSupersymmetric lattice fermions on the triangular lattice: superfrustration and criticality
We study a model for itinerant, strongly interacting fermions where a judicious tuning of the interactions leads to a supersymmetric Hamiltonian. On the triangular lattice this model is known to exhibit a property called superfrustration, which is characterized by an extensive ground state entropy. Using a combination of numerical and analytical methods we study various ladder geometries obtain...
متن کاملMetal–Insulator Transition in the Hubbard Model on a Triangular Lattice with Disorders: Renormalization Group Approach
A multistages block renormalization group approach to study the metal–insulator transition in the Hubbard model on a triangular lattice with hexagonal blocks is presented and implemented. A second-order phase transition with a critical point at U/t 12.5 is obtained (the coupling parameters U and t correspond to the repulsive charging energy and to the nearest-neighbor exchange coupling terms, r...
متن کاملA Mechanism of Spin - Triplet Superconductivity in Hubbard Model on Triangular Lattice : Application to UNi
We discuss the possibility of spin-triplet superconductivity in a two-dimensional Hubbard model on a triangular lattice within the third-order perturbation theory. When we vary the symmetry in the dispersion of the bare energy band from D2 to D6, spin-singlet superconductivity in the D2-symmetric system is suppressed and we obtain spin-triplet superconductivity in near the D6-symmetric system. ...
