Symbolic Dynamics in the Elliptic Isosceles Restricted Three Body Problem
Marcel Guardia, Jaime Paradela, Tere-M. Seara +1
The elliptic isosceles restricted three body problem (REI3BP) models the motion of a massless body under the influence of the Newtonian gravitational force caused by two other bodi…
Variability in NGC 3201 giant stars and its impact on their spectroscopic [Fe/H] determination
Á. Llancaqueo Albornoz, S. Villanova, C. C. Cortés +2
We present the analysis of 34 light curves in and of 17 giant stars in the globular cluster NGC 3201, to check if such stars are variable and if their variability has some…
Thermodynamics of 2+1 dimensional Coulomb-Like Black Holes from Non Linear Electrodynamics with a traceless energy momentum tensor
Mauricio Cataldo, P. A. González, Joel Saavedra +2
In this work we study thermodynamics of 2+1-dimensional static black holes with a nonlinear electric field. Besides employing the standard thermodynamic approach, we investigate th…
Optical theorem and indefinite metric in delta-theory
Ricardo Avila, Carlos M. Reyes
A class of effective field theory called delta-theory, which improves ultraviolet divergences in quantum field theory, is considered. We focus on a scalar model with a quartic self…
Quasi-stationary distribution and metastability for the stochastic Becker-Döring model
Erwan Hingant, Romain Yvinec
We study a stochastic version of the classical Becker-Döring model, a well-known kinetic model for cluster formation that predicts the existence of a long-lived metastable state be…
Magnetic field dependence of nucleon parameters from QCD sum rules
C. A. Dominguez, Luis A. Hernández, Marcelo Loewe +2
Finite energy QCD sum rules involving nucleon current correlators are used to determine several QCD and hadronic parameters in the presence of an external, uniform, large magnetic…
