Quantum light depolarization: the phase-space perspective

A. B. Klimov, J. L. Romero, L. L. Sanchez-Soto +2

Quantum light depolarization is handled through a master equation obtained by coupling dispersively the field to a randomly distributed atomic reservoir. This master equation is so…

Voltage rectification effects in mesoscopic superconducting triangles: experiment and modelling

N. Schildermans, A. B. Kolton, R. Salenbien +3

The interaction of externally applied currents with persistent currents induced by magnetic field in a mesoscopic triangle is investigated. As a consequence of the superposition of…

Modified spontaneous symmetry breaking pattern by brane-bulk interaction terms

Francesco Coradeschi, Stefania De Curtis, Daniele Dominici +1

We show how translational invariance can be broken by the vacuum that drives the spontaneous symmetry breaking of extra-dimensional extensions of the Standard Model, when delta-lik…

Current reversal in collective ratchets induced by lattice instability

L. Dinis, E. M. Gonzalez, J. V. Anguita +2

A collective mechanism for current reversal in superconducting vortex ratchets is proposed. The mechanism is based on a two-dimensional instability of the ground state (T=0) of the…

Experimental test of uncertainty relations for quantum mechanics on a circle

J. Rehacek, Z. Bouchal, R. Celechovsky +2

We rederive uncertainty relations for the angular position and momentum of a particle on a circle by employing the exponential of the angle instead of the angle itself, which leads…

Improved model for the analysis of air fluorescence induced by electrons

F. Arqueros, F. Blanco, J. Rosado

A model recently proposed for the calculation of air-fluorescence yield excited by electrons is revisited. Improved energy distributions of secondary electrons and a more realistic…

Correlation of the highest-energy cosmic rays with the positions of nearby active galactic nuclei

The Pierre Auger Collaboration

Data collected by the Pierre Auger Observatory provide evidence for anisotropy in the arrival directions of the cosmic rays with the highest energies, which are correlated with the…

Electrostatic interactions between graphene layers and their environment

J. Sabio, C. Seoanez, S. Fratini +3

We analyze the electrostatic interactions between a single graphene layer and a SiO susbtrate, and other materials which may exist in its environment. We obtain that the leadin…

A Family of Non-Abelian Kitaev Models on a Lattice: Topological Confinement and Condensation

H. Bombin, M. A. Martin-Delgado

We study a family of non-Abelian topological models in a lattice that arise by modifying the Kitaev model through the introduction of single-qudit terms. The effect of these terms…
