A detailed analysis of dipolar interactions and analytical approximations in arrays of magnetic nanowires
D. Laroze, J. Escrig, P. Landeros +3
The investigation of the role of interactions in magnetic wire arrays is complex and often subject to strong simplifications. In this paper we obtained analytical expressions for t…
Reversal modes in magnetic nanotubes
P. Landeros, S. Allende, J. Escrig +3
The magnetic switching of ferromagnetic nanotubes is investigated as a function of their geometry. Two independent methods are used: Numerical simulations and analytical calculatio…
Propagation of fluctuations in interaction networks governed by the law of mass action
Sergei Maslov, Kim Sneppen, Iaroslav Ispolatov
Using an example of physical interactions between proteins, we study how perturbations propagate in interconnected networks whose equilibrium state is governed by the law of mass a…
Entanglement properties in the Inhomogeneous Tavis-Cummings model
C. E. López, F. Lastra, G. Romero +1
In this work we study the properties of the atomic entanglement in the eigenstates spectrum of the inhomogeneous Tavis-Cummings Model. The inhomogeneity is present in the coupling…
Direct measurement of concurrence for atomic two-qubit pure states
G. Romero, C. E. Lopez, F. Lastra +2
We propose a general scheme to measure the concurrence of an arbitrary two-qubit pure state in atomic systems. The protocol is based on one- and two-qubit operations acting on two…
Single observable concurrence measurement without simultaneous copies
A. Salles, F. de Melo, J. C. Retamal +2
We present a protocol that allows us to obtain the concurrence of any two qubit pure state by performing a minimal and optimal tomography of one of the subsystems through measuring…
Redshift-space limits of bound structures
Rolando Dünner, Andreas Reisenegger, Andrés Meza +2
An exponentially expanding Universe, possibly governed by a cosmological constant, forces gravitationally bound structures to become more and more isolated, eventually becoming cau…
The Peculiar SN 2005hk: Do Some Type Ia Supernovae Explode as Deflagrations?
M. M. Phillips, W. Li, J. A. Frieman +41
We present extensive u'g'r'i'BVRIYJHKs photometry and optical spectroscopy of SN 2005hk. These data reveal that SN 2005hk was nearly identical in its observed properties to SN 2002…
On stochastic fractional Volterra equations in Hilbert space
Anna Karczewska, Carlos Lizama
In this paper stochastic Volterra equations admitting exponentially bounded resolvents are studied. After obtaining convergence of resolvents, some properties of stochastic convolu…
Reversal modes in arrays of interacting magnetic Ni nanowires: Monte Carlo simulations and scaling technique
M. Bahiana, S. Allende, F. S. Amaral +1
The effect of dipolar interactions in hexagonal arrays of Ni nanowires has been investigated by means of Monte Carlo simulations combined with a scaling technique, which allows the…
Effective Quantum Dynamics of Interacting Systems with Inhomogeneous Coupling
C. E. Lopez, H. Christ, J. C. Retamal +1
We study the quantum dynamics of a single mode/particle interacting inhomogeneously with a large number of particles and introduce an effective approach to find the accessible Hilb…
Stochastic Volterra equations driven by cylindrical Wiener process
Anna Karczewska, Carlos Lizama
In this paper, stochastic Volterra equations driven by cylindrical Wiener process in Hilbert space are investigated. Sufficient conditions for existence of strong solutions are giv…
Bosonized supersymmetry of anyons and supersymmetric exotic particle on the non-commutative plane
Peter A. Horvathy, Mikhail S. Plyushchay, Mauricio Valenzuela
A covariant set of linear differential field equations, describing an N=1 supersymmetric anyon system in (2+1)D, is proposed in terms of Wigner's deformation of the bosonic Heisenb…
Dissipative generalized Chaplygin gas as phantom dark energy
Norman Cruz, Samuel Lepe, Francisco Pena
The generalized Chaplygin gas, characterized by the equation of state , has been considered as a model for dark energy due its dark-energy-like evolution at lat…
Hidden nonlinear supersymmetry of finite-gap Lame equation
Francisco Correa, Luis-Miguel Nieto, Mikhail S. Plyushchay
A bosonized nonlinear (polynomial) supersymmetry is revealed as a hidden symmetry of the finite-gap Lame equation. This gives a natural explanation for peculiar properties of the p…
CPT/Lorentz Invariance Violation and Neutrino Oscillation
Paola Arias, Ashok Das, Jorge Gamboa +2
We analyze the consequences of violation of Lorentz and invariance in the massless neutrino sector by deforming the canonical anti-commutation relations for the fields. We sh…
Stability of magnetic configurations in nanorings
P. Landeros, J. Escrig, D. Altbir +2
The relative stability of the vortex, onion and ferromagnetic phases in nanorings is examined as a function of the ring geometry. Total energy calculations are carried out analytic…
Modified Special Relativity on a fluctuating spacetime
R. Aloisio, A. Galante, A. F. Grillo +3
It was recently proposed that deformations of the relativistic symmetry, as those considered in Deformed Special Relativity (DSR), can be seen as the outcome of a measurement theor…
Experimental evidence of accelerated energy transfer in turbulence
R. Labbé, C. Baudet, G. Bustamante
We investigate the vorticity dynamics in a turbulent vortex using scattering of acoustic waves. Two ultrasonic beams are adjusted to probe simultaneously two spatial scales in a gi…
Delayed Scattering of Solitary Waves from Interfaces in a Granular Container
Lautaro Vergara
In granular media, the characterization of the behavior of solitary waves around interfaces is of importance in order to look for more applications of these systems. We study the b…

H. Falomir, J. Gamboa, J. Lopez-Sarrion +2
Charged vortex solutions for noncommutative Maxwell-Higgs model in 3+1 dimensions are found. We show that the stability of these vortex solutions is spoiled out for some, large eno…
