Hysteretic depinning of a particle in a periodic potential: Phase diagram and criticality

V. Purrello, J. L. Iguain, Vivien Lecomte, Alejandro B. Kolton

We consider a massive particle driven with a constant force in a periodic potential and subjected to a dissipative friction. As a function of the drive and damping, the phase diagram of this paradigmatic model is well known to present a pinned, …

Roughening of the anharmonic Larkin model

V. Purrello, J. L. Iguain, Alejandro B. Kolton

We study the roughening of d-dimensional directed elastic interfaces subject to quenched random forces. As in the Larkin model, random forces are considered constant in the displacement direction and uncorrelated in the perpendicular direction. The elastic energy density contains an harmonic part, …

Creep and thermal rounding close to the elastic depinning threshold

V. Purrello, J. L. Iguain, Alejandro B. Kolton, E. A. Jagla

We study the slow stochastic dynamics near the depinning threshold of an elastic interface in a random medium by solving a particularly suited model of hopping interacting particles that belongs to the quenched-Edwards-Wilkinson depinning universality class. The model allows us to compare …

Search for patterns by combining cosmic-ray energy and arrival directions at the Pierre Auger Observatory

A. Aab, P. Abreu, M. Aglietta, E. J. Ahn et autres

Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with [Formula: see text] eV by analyzing cosmic rays with energies above [Formula: see …

Improved limit to the diffuse flux of ultrahigh energy neutrinos from the Pierre Auger Observatory

A. Aab, P. Abreu, M. Aglietta, E. J. Ahn et autres

The Pierre Auger Collaboration reports on its search for ultra high energy (UHE) neutrinos in the EeV range, three orders of magnitude above the highest energy neutrino events reported by IceCube. Analyzing over 9 years of data, the collaboration found no events, …

SEARCHES FOR ANISOTROPIES IN THE ARRIVAL DIRECTIONS OF THE HIGHEST ENERGY COSMIC RAYS DETECTED BY THE PIERRE AUGER OBSERVATORY

A. Aab, P. Abreu, M. Aglietta, E. J. Ahn et autres

We analyze the distribution of arrival directions of ultra-high energy cosmic rays recorded at the Pierre Auger Observatory in 10 years of operation. The data set, about three times larger than that used in earlier studies, includes arrival directions with zenith angles …

Muons in air showers at the Pierre Auger Observatory: Mean number in highly inclined events

A. Aab, P. Abreu, M. Aglietta, E. J. Ahn et autres

The Pierre Auger collaboration reports new results bearing on the composition of cosmic rays. The muon number of air showers, created by cosmic rays and measured by the collaboration, is intriguingly at odds with all theoretical models, posing a challenge to our …

Depth of maximum of air-shower profiles at the Pierre Auger Observatory. II. Composition implications

A. Aab, P. Abreu, M. Aglietta, E. J. Ahn et autres

Using the data taken at the Pierre Auger Observatory between December 2004 and December 2012, we have examined the implications of the distributions of depths of atmospheric shower maximum (${X}_{\mathrm{max}}$), using a hybrid technique, for composition and hadronic interaction models. We do …
