Numerical evidences of a universal critical behavior of 2D and 3D random quantum clock and Potts models
Valentin Anfray, Christophe Chatelain
The random quantum -state clock and Potts models are studied in 2 and 3 dimensions. The existence of Griffiths phases is tested in the 2D case with by sampling the integra…
Finite-Size Scaling of the majority-voter model above the upper critical dimension
Christophe Chatelain
The majority-voter model is studied by Monte Carlo simulations on hypercubic lattices of dimension to 7 with periodic boundary conditions. The critical exponents associated t…
Absence of logarithmic divergence of the entanglement entropies at the phase transitions of a 2D classical hard rod model
Christophe Chatelain, Andrej Gendiar
Entanglement entropy is a powerful tool to detect continuous, discontinuous and even topological phase transitions in quantum as well as classical systems. In this work, von Neuman…
Diverging conductance at the contact between random and pure quantum XX spin chains
Christophe Chatelain
A model consisting in two quantum XX spin chains, one homogeneous and the second with random couplings drawn from a binary distribution, is considered. The two chains are coupled t…
Infinite disorder and correlation fixed point in the Potts model with correlated disorder
Christophe Chatelain
Recent Monte Carlo simulations of the q-state Potts model with a disorder displaying slowly-decaying correlations reported a violation of hyperscaling relation caused by large diso…
Numerical study of the critical phases of the frustrated Z(5) model
Christophe Chatelain
The phase diagram of the spin model is studied numerically on the square lattice by means of the {\sl Density Matrix Renormalization Group}. In the regime where the…
