Self-dual Chern-Simons solitons in noncommutative space
G. S. Lozano, E. F. Moreno, F. A. Schaposnik
We construct exact soliton solutions to the Chern-Simons-Higgs system in noncommutative space, for non-relativistic and relativistic models. In both cases we find regular vortex-li…
Dynamical quenching and annealing in self-organization multiagent models
E. Burgos, H. Ceva, R. P. J. Perazzo
We study the dynamics of a generalized Minority Game (GMG) and of the Bar Attendance Model (BAM) in which a number of agents self-organize to match an attendance that is fixed exte…
Collisionless collective modes of fermions in magnetic traps
P. Capuzzi, E. S. Hernandez
We present a Random-Phase-Approximation formalism for the collective spectrum of two hyperfine species of dilute 40K atoms, magnetically trapped at zero temperature and subjected t…
Localic Galois Theory
Eduardo J. Dubuc
In Proposition I of "Memoire sur les conditions de resolubilite des equations par radicaux", Galois established that any intermediate extension of the splitting field of a polynomi…
Nielsen-Olesen vortices in noncommutative space
G. S. Lozano, E. F. Moreno, F. A. Schaposnik
We construct an exact regular vortex solution to the self-dual equations of the Abelian Higgs model in non-commutative space for arbitrary values of . To this end, we propose an…
Resonant photon creation in a three dimensional oscillating cavity
Martin Crocce, Diego A. R. Dalvit, Francisco D. Mazzitelli
We analyze the problem of photon creation inside a perfectly conducting, rectangular, three dimensional cavity with one oscillating wall. For some particular values of the frequenc…
