Ballistic deposition on deterministic fractals: On the observation of discrete scale invariance
Claudio M. Horowitz, Federico Roma, Ezequiel V. Albano
The growth of ballistic aggregates on deterministic fractal substrates is studied by means of numerical simulations. First, we attempt the description of the evolving interface of…
Nonequilibrium critical dynamics of the three-dimensional gauge glass
F. Roma, D. Dominguez
We study the non-equilibrium aging behavior of the gauge glass model in three dimensions at the critical temperature. We perform Monte Carlo simulations with a Metropolis update, a…
Entropy-driven phase transition in a system of long rods on a square lattice
D. H. Linares, F. Roma, A. J. Ramirez-Pastor
The isotropic-nematic (I-N) phase transition in a system of long straight rigid rods of length k on square lattices is studied by combining Monte Carlo simulations and theoretical…
Fractal dimension of domain walls in the Edwards-Anderson spin glass model
S. Risau-Gusman, F. Roma
We study directly the length of the domain walls (DW) obtained by comparing the ground states of the Edwards-Anderson spin glass model subject to periodic and antiperiodic boundary…
Critical behavior of repulsive dimers on square lattices at 2/3 monolayer coverage
F. Roma, J. L. Riccardo, A. J. Ramirez-Pastor
Monte Carlo simulations and finite-size scaling theory have been used to study the critical behavior of repulsive dimers on square lattices at 2/3 monolayer coverage. A "zig-zag" (…
A c-theorem for the entanglement entropy
H. Casini, M. Huerta
The combination of the Lorentz symmetry and the strong subadditive property of the entropy leads to a c-theorem for the entanglement entropy in 1+1 dimensions. We present a simple…
