String-Like BTZ on Codimension-2 Braneworlds in the Thin Brane Limit
Bertha Cuadros-Melgar, Eleftherios Papantonopoulos, Minas Tsoukalas +1
We consider five-dimensional gravity with a Gauss-Bonnet term in the bulk and an induced gravity term on a 2-brane of codimension-2. We show that this system admits BTZ black holes…
Instability of the Time Dependent Horava-Witten Model
B. Cuadros-Melgar, C. E. Pellicer
We consider scalar perturbations in the time-dependent Hourava-Witten Model in order to probe its stability. We show that during the non-singular epoque the model evolves without i…
Solitary wave trains in granular chains: Experiments, theory and simulations
Stephane Job, Francisco Melo, Adam Sokolow +1
The features of solitary waves observed in horizontal monodisperse chain of barely touching beads not only depend on geometrical and material properties of the beads but also on th…
Anisotropic harmonic oscillator, non-commutative Landau problem and exotic Newton-Hooke symmetry
Pedro D. Alvarez, Joaquim Gomis, Kiyoshi Kamimura +1
We investigate the planar anisotropic harmonic oscillator with explicit rotational symmetry as a particle model with non-commutative coordinates. It includes the exotic Newton-Hook…
Vortex core size in interacting cylindrical nanodot arrays
D. Altbir, J. Escrig, P. Landeros +2
The effect of dipolar interactions among cylindrical nanodots, with a vortex-core magnetic configuration, is analyzed by means of analytical calculations. The cylinders are placed…
Remanence of Ni nanowire arrays: Influence of size and labyrinth magnetic structure
J. Escrig, D Altbir, M. Jaafar +3
The influence of the macroscopic size of the Ni nanowire array system on their remanence state has been investigated. A simple magnetic phenomenological model has been developed to…
Angular dependence of coercivity in magnetic nanotubes
J. Escrig, M. Daub, P. Landeros +2
The nucleation field for infinite magnetic nanotubes, in the case of a magnetic field applied parallel to the long axis of the tubes, is calculated as a function of their geometric…
Multi-Fluid Simulation of the Magnetic Field Evolution in Neutron Stars
Jaime Hoyos, Andreas Reisenegger, Juan A. Valdivia
Using a numerical simulation, we study the effects of ambipolar diffusion and ohmic diffusion on the magnetic field evolution in the interior of an isolated neutron star. We are in…
Bosonized supersymmetry from the Majorana-Dirac-Staunton theory and massive higher-spin fields
Peter A. Horvathy, Mikhail S. Plyushchay, Mauricio Valenzuela
We propose a (3+1)D linear set of covariant vector equations, which unify the spin 0 ``new Dirac equation'' with its spin 1/2 counterpart, proposed by Staunton. Our equations descr…
Electroweak quark-lepton symmetry and weak topological-charge confinement in the Standard Model with Dirac neutrinos
Ernesto A. Matute
The standard electroweak model with Dirac neutrinos is extended by way of the principles of electroweak quark-lepton symmetry and weak topological-charge confinement to account for…
Current-Induced Torques in Magnetic Metals: Beyond Spin Transfer
P. M. Haney, R. A. Duine, A. S. Nunez +1
Current-induced torques on ferromagnetic nanoparticles and on domain walls in ferromagnetic nanowires are normally understood in terms of transfer of conserved spin angular momentu…
Asymptotic normality for the counting process of weak records and δ-records in discrete models
Raúl Gouet, F. Javier López, Gerardo Sanz
Let be a sequence of independent and identically distributed random variables, taking non-negative integer values, and call a -record if $X_n>\max\{X_1,...…
Anisotropic Cosmological Constant and the CMB Quadrupole Anomaly
Davi C. Rodrigues
There are evidences that the cosmic microwave background (CMB) large-angle anomalies imply a departure from statistical isotropy and hence from the standard cosmological model. We…
Hidden nonlinear su(2|2) superunitary symmetry of N=2 superextended 1D Dirac delta potential problem
Francisco Correa, Luis-Miguel Nieto, Mikhail S. Plyushchay
We show that the N=2 superextended 1D quantum Dirac delta potential problem is characterized by the hidden nonlinear superunitary symmetry. The unexpected feature of this…
Chiral Anomaly Beyond Lorentz Invariance
P. Arias, H. Falomir, J. Gamboa +2
The chiral anomaly in the context of an extended standard model with minimal Lorentz invariance violation is studied. Taking into account bounds from measurements of the speed of l…
Radial distribution of the inner magnetosphere plasma pressure using low-altitude satellite data during geomagnetic storm: the March 1-8, 1982 Event
M. Stepanova, E. E. Antonova, J. M. Bosqued
Plasma pressure distribution in the inner magnetosphere is one of the key parameters for understanding the main magnetospheric processes including geomagnetic storms and substorms.…
Peculiarities of the hidden nonlinear supersymmetry of Poschl-Teller system in the light of Lame equation
Francisco Correa, Mikhail S. Plyushchay
A hidden nonlinear bosonized supersymmetry was revealed recently in Poschl-Teller and finite-gap Lame systems. In spite of the intimate relationship between the two quantum models,…
Selective Control of the Symmetric Dicke Subspace in Trapped Ions
C. E. Lopez, J. C. Retamal, E. Solano
We propose a method of manipulating selectively the symmetric Dicke subspace in the internal degrees of freedom of N trapped ions. We show that the direct access to ionic-motional…
Planar Embeddings with a Globally Attracting Fixed Point
Begona Alarcon, Victor Guinez, Carlos Gutierrez
We consider sufficient conditions which guarantee that a planar embedding has a unique fixed point. We study sufficient conditions which imply the appearing of a globally attractin…
Abrupt Changes in the Dynamics of Quantum Disentanglement
F. Lastra, G. Romero, C. E. López +2
Entanglement evolution in high dimensional bipartite systems under dissipation is studied. Discontinuities for the time derivative of the lower bound of entanglement of formation i…
Quantum information transfer for qutrits
A. Delgado, C. Saavedra, J. C. Retamal
We propose a scheme for the transfer of quantum information among distant qutrits. We apply this scheme to the distribution of entanglement among distant nodes and to the generatio…

Pedro D. Alvarez, Joaquim Gomis, Kiyoshi Kamimura +1
A particle system with a (2+1)D exotic Newton-Hooke symmetry is constructed by the method of nonlinear realization. It has three essentially different phases depending on the value…
