Self-organization in a simple model of adaptive agents playing 2X2 games with arbitrary payoff matrices

H. Fort, S. Viola

We analyze, both analytically and numerically, the self-organization of a system of "selfish" adaptive agents playing an arbitrary iterated pairwise game (defined by a 2X2 payoff m…

Synchronization of globally coupled nonidentical maps with inhomogeneous delayed interactions

Arturo C. Marti, C. Masoller

We study the synchronization of a coupled map lattice consisting of a one-dimensional chain of logistic maps. We consider global coupling with a time-delay that takes into account…

Quantum random walk on the line as a markovian process

A. Romanelli, A. C. Sicardi-Schifino, R. Siri +3

We analyze in detail the discrete--time quantum walk on the line by separating the quantum evolution equation into Markovian and interference terms. As a result of this separation,…

Noise spectroscopy of non-linear magneto optical resonances in Rb vapor

M. Martinelli, P. Valente, H. Failache +4

Nonlinear magneto-optical (NMO) resonances occurring for near-zero magnetic field are studied in Rb vapor using light-noise spectroscopy. With a balanced detection polarimeter, we…

Non Perturbative Renormalization Group study of reaction-diffusion processes and directed percolation

Léonie Canet, Bertrand Delamotte, Olivier Deloubrière +1

We investigate non-equilibrium critical phenomena using a nonperturbative renormalization group method. Reaction-diffusion processes are described by a scale dependent effective ac…

Physical properties of single-crystalline fibers of the colossal-magnetoresistance manganite La0.7Ca0.3MnO3

C. A. Cardoso, F. M. Araujo-Moreira, M. R. B. Andreeta +5

We have grown high-quality single crystals of the colossal-magnetoresistance (CMR) material La0.7Ca0.3MnO3 by using the laser heated pedestal growth (LHPG) method. Samples were gro…

Cooperation and Self-Regulation in a Model of Agents Playing Different Games

H. Fort

A simple model for cooperation between "selfish" agents, which play an extended version of the Prisoner's Dilemma(PD) game, in which they use arbitrary payoffs, is presented and st…

Discrete quantum gravity: a mechanism for selecting the value of fundamental constants

Rodolfo Gambini, Jorge Pullin

Smolin has put forward the proposal that the universe fine tunes the values of its physical constants through a Darwinian selection process. Every time a black hole forms, a new un…

Consistent discrete gravity solution of the problem of time: a model

Rodolfo Gambini, Rafael Porto, Jorge Pullin

The recently introduced consistent discrete lattice formulation of canonical general relativity produces a discrete theory that is constraint-free. This immediately allows to overc…
