Topological insight into the non-Arrhenius mode hopping of semiconductor ring lasers
S. Beri, L. Gelens, M. Mestre +6
We investigate both theoretically and experimentally the stochastic switching between two counter-propagating lasing modes of a semiconductor ring laser. Experimentally, the reside…
Econophysics: Empirical facts and agent-based models
Anirban Chakraborti, Ioane Muni Toke, Marco Patriarca +1
This article aims at reviewing recent empirical and theoretical developments usually grouped under the term Econophysics. Since its name was coined in 1995 by merging the words Eco…
Surface mixing and biological activity in the four Eastern Boundary Upwelling Systems
V. Rossi, C. Lopez, E. Hernandez-Garcia +3
Eastern Boundary Upwelling Systems (EBUS) are characterized by a high productivity of plankton associated with large commercial fisheries, thus playing key biological and socio-eco…
Drifting instabilities of cavity solitons in vertical cavity surface-emitting lasers with frequency selective feedback
P. V. Paulau, D. Gomila, P. Colet +3
In this paper we study the formation and dynamics of self-propelled cavity solitons (CSs) in a model for vertical cavity surface-emitting lasers (VCSELs) subjected to external freq…
Residential segregation and cultural dissemination: An Axelrod-Schelling model
C. Gracia-Lazaro, L. F. Lafuerza, L. M. Floria +1
In the Axelrod's model of cultural dissemination, we consider mobility of cultural agents through the introduction of a density of empty sites and the possibility that agents in a…
Optimal electron propagation on a quantum chain by a topological phase
S. Paganelli, G. L. Giorgi, F. de Pasquale
We study the quantum diffusion of an electron in a quantum chain starting from an initial state localized around a given site. As the wavepacket diffuses, the probability of recons…
