Phase transition of the six-state clock model observed from the entanglement entropy
Roman Krčmár, Andrej Gendiar, Tomotoshi Nishino
The Berezinskii-Kosterlitz-Thouless (BKT) transitions of the six-state clock model on the square lattice are investigated by means of the corner-transfer matrix renormalization gro…
Quasi-universality in mixed counterions systems
M. Trulsson, L. Samaj, E. Trizac
The screening of plate-plate interactions by counterions is an age-old problem. We revisit this classic question when counterions exhibit a distribution of charges. While it is exp…
Enhanced magnetocaloric effect in a proximity of magnetization steps and jumps of spin-1/2 XXZ Heisenberg regular polyhedra
K. Karlova, J. Strecka, J. Richter
The magnetization process and adiabatic demagnetization of the antiferromagnetic spin-1/2 XXZ Heisenberg clusters with the shape of regular polyhedra (tetrahedron, octahedron, cube…
Critical properties of the eight-vertex model in a field
Roman Krčmár, Ladislav Šamaj
The general eight-vertex model on a square lattice is studied numerically by using the Corner Transfer Matrix Renormalization Group method. The method is tested on the symmetric (z…
Thermal entanglement and sharp specific-heat peak in an exactly solved spin-1/2 Ising-Heisenberg ladder with alternating Ising and Heisenberg inter-leg couplings
Onofre Rojas, J. Strečka, S. M. de Souza
The spin-1/2 Ising-Heisenberg two-leg ladder accounting for alternating Ising and Heisenberg inter-leg couplings in addition to the Ising intra-leg coupling is rigorously mapped on…
Boundary-field-driven control of discontinuous phase transitions on hyperbolic lattices
Yoju Lee, Frank Verstraete, Andrej Gendiar
The multistate Potts models on two-dimensional hyperbolic lattices are studied with respect to various boundary effects. The free energy is numerically calculated by Corner Transfe…
Amplitude Function of Asymptotic Correlations Along Charged Wall in Coulomb Fluids
Ladislav Šamaj
In classical semi-infinite Coulomb fluids, two-point correlation functions exhibit a slow inverse-power law decay along a uniformly charged wall. In this work, we concentrate on th…
Reentrant disorder-disorder transitions in generalized multicomponent Widom-Rowlinson models
Roman Krčmár, Ladislav Šamaj
In the lattice version of the multicomponent Widom-Rowlinson (WR) model, each site can be either empty or singly occupied by one of different particles, all species having the…
