Finite-size scaling for Mott metal-insulator transition on a half-filled non-partite lattice
Jiaxiang Wang, Sabre Kais
By applying a multi-stage real-space renormalization group procedure to Hubbard model, we examine the finite-size scaling in Mott metal-insulator transition(MIT) on a non-partite l…

Combined effects of disorders and electron-electron interactions upon metal-insulator transition in 2D non-bipartite lattice
Jiaxiang Wang, Sabre Kais
We examined the characteristics of a metal-insulator transition on a two-dimensional non-bipartite lattice when both disorders and electron interactions are present. Using a real-s…

Real-space renormalization group study of the Hubbard model on a non-bipartite lattice
J. X. Wang, Sabre Kais, R. D. Levine
We present the real-space block renormalization group equations for fermion systems described by a Hubbard Hamiltonian on a triangular lattice with hexagonal blocks. The conditions…
