Critical exponents and universality for the isotropic-nematic phase transition in a system of self-assembled rigid rods on a lattice
(American Physical Society, 2009-10)
Monte Carlo simulations have been carried out for a system of monomers on square lattices that, by decreasing temperature or increasing density, polymerize reversibly into chains with two allowed directions and, at the ...
Concentrating solutions for a planar elliptic problem involving nonlinearities with large exponent
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006)
We consider the boundary value problem Delta u + u(P) = 0 in a bounded, smooth domain Omega in R-2 with homogeneous Dirichlet boundary condition and p a large exponent. We find topological conditions on Omega which ensure ...
Defining universality classes for three different local bifurcations
(2016-10-01)
The convergence to the fixed point at a bifurcation and near it is characterized via scaling formalism for three different types of local bifurcations of fixed points in differential equations, namely: (i) saddle-node; ...
The critical exponent of nuclear fragmentation
(Springer, 2003-12)
Nuclei colliding at energies in the MeV's break into fragments in a process that resembles a liquid-to-gas phase transition of the excited nuclear matter. If this is the case, phase changes occurring near the critical point ...
Universality in short-range Ising spin glasses
(1999)
The role of the distribution of coupling constants in the critical exponents of the short-range Ising spin-glass model is investigated via real space renormalization group. A saddle-point spin glass critical point characterized ...
Critical behavior of a contact process with aperiodic transition rates
(IOP PUBLISHING LTD, 2008)
We performed Monte Carlo simulations to investigate the steady-state critical behavior of a one-dimensional contact process with an aperiodic distribution of rates of transition. As in the presence of randomness, spatial ...
Nonsteady relaxation and critical exponents at the depinning transition
(American Physical Society, 2013-03-11)
We study the nonsteady relaxation of a driven one-dimensional elastic interface at the depinning transition by extensive numerical simulations concurrently implemented on graphics processing units. We compute the time-dependent ...
Critical points of the regular part of the harmonic Green function with Robin boundary condition

On elliptic problems involving critical Hardy-Sobolev exponents and sign-changing function
(Pergamon-elsevier Science LtdOxfordInglaterra, 2010)
Erratum: Nonsteady relaxation and critical exponents at the depinning transition [Phys. Rev. E 87, 032122 (2013)]
(American Physical Society, 2013-06-12)
We found some misprints in our paper. Since some of them are in equations, we believe it is necessary to add this erratum.The conclusions of our work remain unchanged in spite of these corrections.
