Ashkin-Teller phase transition and multicritical behavior in a classical monomer-dimer model
Satoshi Morita, Hyun-Yong Lee, Kedar Damle +1
We use Monte Carlo simulations and tensor network methods to study a classical monomer-dimer model on the square lattice with a hole (monomer) fugacity , an aligning dimer-dimer…
Ground-state phase diagram of a spin-1/2 frustrated XXZ ladder
Takuhiro Ogino, Ryui Kaneko, Satoshi Morita +1
We study the ground-state phase diagram of a spin- frustrated XXZ ladder, in which two antiferromagnetic chains are coupled by competing rung and diagonal interactions…
TeNeS: Tensor Network Solver for Quantum Lattice Systems
Yuichi Motoyama, Tsuyoshi Okubo, Kazuyoshi Yoshimi +3
TeNeS (Tensor Network Solver) is a free/libre open-source software program package for calculating two-dimensional many-body quantum states based on the tensor network method and t…
Non-monotonic behavior of the Binder Parameter in the discrete spin systems
Hiroshi Watanabe, Yuichi Motoyama, Satoshi Morita +1
We study a non-monotonic behavior of the Binder parameter, which appears in the discrete spin systems. We show that the Binder parameters of the Potts model are non-monotonic for $…
Symmetry-protected topological phases and competing orders in a spin-1/2 XXZ ladder with a four-spin interaction
Takuhiro Ogino, Shunsuke Furukawa, Ryui Kaneko +2
We study a spin-1/2 XXZ model with a four-spin interaction on a two-leg ladder. By means of effective field theory and matrix product state calculations, we obtain rich ground-stat…
Mott Insulator-like Bose-Einstein Condensation in a Tight-Binding System of Interacting Bosons with a Flat Band
Hosho Katsura, Naoki Kawashima, Satoshi Morita +2
We propose a new class of tight-binding systems of interacting bosons with a flat band, which are exactly solvable in the sense that one can explicitly write down the unique ground…
