Holographic kinetic k-essence model
Norman Cruz, Pedro F. Gonzalez-Diaz, Alberto Rozas-Fernandez +1
We consider a connection between the holographic dark energy density and the kinetic k-essence energy density in a flat FRW universe. With the choice , the holographic dark…
SU(2) Kinetic Mixing Terms and Spontaneous Symmetry Breaking
J. Lopez-Sarrion, Paola Arias, J. Gamboa
The non-abelian generalization of the Holdom model --{\it i.e.} a theory with two gauge fields coupled to the kinetic mixing term -- is considered. C…
Microwave Photon Detector in Circuit QED
G. Romero, J. J. Garcia-Ripoll, E. Solano
Quantum optical photodetection has occupied a central role in understanding radiation-matter interactions. It has also contributed to the development of atomic physics and quantum…
Aharonov-Bohm effect on AdS_2 and nonlinear supersymmetry of reflectionless Poschl-Teller system
Francisco Correa, Vit Jakubsky, Mikhail S. Plyushchay
We explain the origin and the nature of a special nonlinear supersymmetry of a reflectionless Poschl-Teller system by the Aharonov-Bohm effect for a nonrelativistic particle on the…
Non-commutative Supersymmetric Quantum Mechanics
Ashok Das, H. Falomir, J. Gamboa +1
General non-commutative supersymmetric quantum mechanics models in two and three dimensions are constructed and some two and three dimensional examples are explicitly studied. The…
Time delay of light signals in an energy-dependent spacetime metric
A. F. Grillo, E. Luzio, F. Mendez
In this note we review the problem of time delay of photons propagating in a spacetime with a metric that explicitly depends on the energy of the particles (Gravity-Rainbow approac…
Holographic dark energy interacting with dark matter in a Closed Universe
Norman Cruz, Samuel Lepe, Francisco Pena +1
A cosmological model of an holographic dark energy interacting with dark matter throughout a decaying term of the form is investigated. General constrai…
Large Deviations of the Front in a one dimensional model of
Jean Bérard, Alejandro Ramírez
We investigate the probabilities of large deviations for the position of the front in a stochastic model of the reaction on the integer lattice in which particles…
Acoustic emission associated with the bursting of a gas bubble at the free surface of a non-newtonian fluid
Thibaut Divoux, Valérie Vidal, Francisco Melo +1
We report experimental measurements of the acoustic emission associated with the bursting of a gas bubble at the free surface of a non-newtonian fluid. On account of the viscoelast…
Evolution of Anisotropies in Eddington-Born-Infeld Cosmology
Davi C. Rodrigues
Recently a Born-Infeld action for dark energy and dark matter that uses additional affine connections was proposed. At background level, it was shown that the new proposal can mimi…
Finite-gap systems, tri-supersymmetry and self-isospectrality
Francisco Correa, Vit Jakubsky, Mikhail S. Plyushchay
We show that an n-gap periodic quantum system with parity-even smooth potential admits isospectral super-extensions. Each is described by a tri-supersymmetry that originate…
Segregation induced by inelasticity in a vibrofluidized granular mixture
R. Brito, H. Enríquez, S. Godoy +1
We investigate the segregation of a dense binary mixture of granular particles that only differ in their restitution coefficient. The mixture is vertically vibrated in the presence…
Radiative processes as a condensation phenomenon and the physical meaning of deformed canonical structures
J. Gamboa, L. S. Grigorio, M. S. Guimaraes +2
Working with well known models in we discuss the physics behind the deformation of the canonical structure of these theories. A new deformation is constructed linking the…
Dark energy interacting with two fluids
Norman Cruz, Samuel Lepe, Francisco Pena
A cosmological model of dark energy interacting with dark matter and another general component of the universe is investigated. We found general constraints on these models imposin…
Stone-Weierstrass type theorems for large deviations
Henri Comman
We give a general version of Bryc's theorem valid on any topological space and with any algebra of real-valued continuous functions separating the points, or any well…
Invariant measures of minimal post-critical sets of logistic maps
María Isabel Cortez, Juan Rivera-Letelier
We construct logistic maps whose restriction to the omega-limit set of its critical point is a minimal Cantor system having a prescribed number of distinct ergodic and invariant pr…
Black Holes on Thin 3-branes of Codimension-2 and their Extension into the Bulk
Bertha Cuadros-Melgar, Eleftherios Papantonopoulos, Minas Tsoukalas +1
We discuss black hole solutions in six-dimensional gravity with a Gauss-Bonnet term in the bulk and an induced gravity term on a thin 3-brane of codimension-2. We show that these b…
Effects of heavy bosonic excitations on QED vacuum
Paola Arias, Horacio Falomir, Jorge Gamboa +1
We discuss the contribution of axion-like excitations (ALE) to the vacuum birrefringence in the limit , where is the mass of the excitation and the energy…
Gluon density and functions from BK equation with impact parameter dependence
Sergey Bondarenko
In this note we fix the preliminary results obtained in the study of gluon density function of the paper \cite{bom3}. The LO BK equation for unintegrated gluon density with impact…
Sudden Birth Versus Sudden Death of Entanglement in Multipartite Systems
C. E. Lopez, G. Romero, F. Lastra +2
We study the entanglement dynamics of two cavities interacting with independent reservoirs. Expectedly, we observe that, as the cavity entanglement is depleted, it is transferred t…
Axions and "Light Shining Through a Wall": A Detailed Theoretical Analysis
Stephen L. Adler, J. Gamboa, F. Mendez +1
We give a detailed study of axion-photon and photon-axion conversion amplitudes, which enter the analysis of ``light shining through a wall'' experiments. Several different calcula…
