Risk and interaction aversion: screening mechanisms in the Prisoner's Dilemma game
Gabriel A. Canova, J. J. Arenzon
When the interactions between cooperators (C) and defectors (D) can be partially avoided within a population, there may be an overall enhancement of cooperation. One example of suc…
Competing nematic interactions in a generalized XY model in two and three dimensions
Gabriel A. Canova, Yan Levin, Jeferson J. Arenzon
We study a generalization of the XY model with an additional nematic-like term through extensive numerical simulations and finite-size techniques, both in two and three dimensions.…
Kosterlitz-Thouless and Potts transitions in a generalized XY model
Gabriel A. Canova, Yan Levin, Jeferson J. Arenzon
We present extensive numerical simulations of a generalized XY model with nematic-like terms recently proposed by Poderoso {\it et al} [PRL 106(2011)067202]. Using finite size scal…
Reply to "Incommensurate vortices and phase transitions in two-dimensional XY models with interaction having auxiliary minima" by S. E. Korshunov
G. A. Canova, F. C. Poderoso, J. J. Arenzon +1
We present a rigorous proof and extensive numerical simulations showing the existence of a transition between the paramagnetic and nematic phases, in a class of generalized XY mode…
