Boundary CFT and tensor network approach to surface critical phenomena of the tricritical 3-state Potts model
Shumpei Iino
One-dimensional edges of classical systems in two dimension sometimes show surprisingly rich phase transitions and critical phenomena, particularly when the bulk is at criticality.…
Open spin chain realization of topological defect on 1d Ising model and boundary and bulk symmetry
Yoshiki Fukusumi, Shumpei Iino
We study the realizations of topological defects in 1d quantum Ising model with open boundary condition at criticality. Applying the construction discussed in [M. Hauru, G. Evenbly…
Boundary conformal spectrum and surface critical behaviors of the classical spin systems: a tensor network renormalization study
Shumpei Iino, Satoshi Morita, Naoki Kawashima
We numerically obtain the conformal spectrum of several classical spin models on a two-dimensional lattice with open boundaries, for every boundary fixed point obtained by the Card…
Boundary Tensor Renormalization Group
Shumpei Iino, Satoshi Morita, Naoki Kawashima
We develop the tensor renormalization group (TRG) algorithm for statistical systems with open boundaries, which allows us to investigate not only the bulk but also the boundary pro…
Detecting signals of weakly first-order phase transitions in two-dimensional Potts models
Shumpei Iino, Satoshi Morita, Anders W. Sandvik +1
We investigate the first-order phase transitions of the -state Potts models with , and on the two-dimensional square lattice, using Monte Carlo simulations. At…
