Absorption-desorption phase transition induced by parametric modulation Van den Broeck Limburgs Universitair Centrum, B-3590 Diepenbeek, Belgium Ryoichi Kawai Department of Physics, University of Alabama at Birmingham, Birmingham, Alabama 35294 We present a nonequilibrium absorption-desorption phase transition, induced by a time-periodic parametric modulation, and compare it with the phase transitions induced by white and dichotomous Markov noise. In the case of time-periodic modulation and dichotomous Markov noise, the phase transition is found to be reentrant with respect to the strength of the spatial coupling. URL: .
