Organization and clasification of trajectories in the time-delayed Mackey-Glass system
Pablo Amil, Cecilia Cabeza, Cristina Masoller +1
Using a novel electronic implementation of a well-known time-delayed system, the Mackey-Glass (MG) system, we investigate the organization of the trajectories in the phase space, a…
Optimal algorithms for universal random number generation from finite memory sources
Gadiel Seroussi, Marcelo J. Weinberger
We study random number generators (RNGs), both in the fixed to variable-length (FVR) and the variable to fixed-length (VFR) regimes, in a universal setting in which the input is a…
Deconfinement transition in SU(2) Yang-Mills theory: A two-loop study
U. Reinosa, J. Serreau, M. Tissier +1
In a recent work we have proposed a perturbative approach for the study of the phase transition of pure Yang-Mills theories at finite temperature. This is based on a simple massive…
Majorana neutrinos production at LHeC in an effective approach
Lucía Duarte, Gabriel A. González-Sprinberg, Oscar Alfredo Sampayo
We investigate the possibility of detecting Majorana neutrinos at the Large Hadron-electron Collider (LHeC), an electron-proton collision mode at CERN. We study the $l_j^{+} + 3 je…
Fragments' internal and kinetic temperatures in the framework of a Nuclear Statistical Multifragmentation Model
S. R. Souza, B. V. Carlson, R. Donangelo +2
The agreement between the fragments' internal and kinetic temperatures with the breakup temperature is investigated using a Statistical Multifragmentation Model which makes no a pr…
A geometrically motivated parametric model in manifold estimation,
José R. Berrendero, Alejandro Cholaquidis, Antonio Cuevas +1
The general aim of manifold estimation is reconstructing, by statistical methods, an -dimensional compact manifold on (with ) or estimating some rel…
Fully developed isotropic turbulence: nonperturbative renormalization group formalism and fixed point solution
Léonie Canet, Bertrand Delamotte, Nicolás Wschebor
We investigate the regime of fully developed homogeneous and isotropic turbulence of the Navier-Stokes (NS) equation in the presence of a stochastic forcing, using the nonperturbat…
Fully developed isotropic turbulence: symmetries and exact identities
Léonie Canet, Bertrand Delamotte, Nicolás Wschebor
We consider the regime of fully developed isotropic and homogeneous turbulence of the Navier-Stokes equation with a stochastic forcing. We present two gauge symmetries of the corre…
Eigenvalues and Entropy of a Hitchin representation
Rafael Potrie, Andrés Sambarino
We show that the critical exponent of a representation in the Hitchin component of is bounded above, the least upper bound being attained only in the Fuchsian l…
On laminar groups, Tits alternatives, and convergence group actions on
Juan Alonso, Hyungryul Baik, Eric Samperton
Following previous work of the second author, we establish more properties of groups of circle homeomorphisms which admit invariant laminations. In this paper, we focus on a certai…
On visual distances for spectrum-type functional data
Alejandro Cholaquidis, Antonio Cuevas, Ricardo Fraiman
A functional distance , based on the Hausdorff metric between the function hypographs, is proposed for the space of non-negative real upper semicontinuo…
Set estimation from reflected Brownian motion
Alejandro Cholaquidis, Ricardo Fraiman, Gábor Lugosi +1
We study the problem of estimating a compact set from a trajectory of a reflected Brownian motion in with reflections on the boundary of . We establi…
A unified approach to linear probing hashing with buckets
Svante Janson, Alfredo Viola
We give a unified analysis of linear probing hashing with a general bucket size. We use both a combinatorial approach, giving exact formulas for generating functions, and a probabi…
Average polynomial time for eigenvector computations
Diego Armentano, Carlos Beltrán, Michael Shub
We describe two algorithms for the eigenvalue, eigenvector problem which, on input a Gaussian matrix with complex entries, finish with probability 1 and in average polynomial time.
A ring system detected around the Centaur (10199) Chariklo
F. Braga-Ribas, B. Sicardy, J. L. Ortiz +61
Until now, rings have been detected in the Solar System exclusively around the four giant planets. Here we report the discovery of the first minor-body ring system around the Centa…
Off-axis retrieval of orbital angular momentum of light stored in cold atoms
R. A. de Oliveira, L. Pruvost, P. S. Barbosa +5
We report on the storage of orbital angu- lar momentum (OAM) of light of a Laguerre-Gaussian mode in an ensemble of cold cesium atoms and its re- trieval along an axis different fr…
Massive renormalization scheme and perturbation theory at finite temperature
Jean-Paul Blaizot, Nicolas Wschebor
We argue that the choice of an appropriate, massive, renormalization scheme can greatly improve the apparent convergence of perturbation theory at finite temperature. This is illus…
The role of intermediaries in the synchronization of pulse-coupled oscillators
Rodrigo A. García, Nicolás Rubido, Arturo C. Marti +1
The role of intermediaries in the synchronization of small groups of light controlled oscillators (LCO) is addressed. A single LCO is a two-time-scale phase oscillator. When pulse-…
Strong-coupling phases of the anisotropic Kardar-Parisi-Zhang equation
Thomas Kloss, Léonie Canet, Nicolás Wschebor
We study the anisotropic Kardar-Parisi-Zhang equation using nonperturbative renormalization group methods. In contrast to a previous analysis in the weak-coupling regime we find th…
Dominated Splitting, Partial Hyperbolicity and Positive Entropy
Eleonora Catsigeras, Xueting Tian
Let be a diffeomorphism with a dominated splitting on a compact Riemanian manifold without boundary. We state and prove several sufficient conditions f…
Stochastic Perturbations of Convex Billiards
Roberto Markarian, Leonardo T. Rolla, Vladas Sidoravicius +2
We consider a strictly convex billiard table with boundary, with the dynamics subjected to random perturbations. Each time the billiard ball hits the boundary its reflection…
Influence of the density of states on the odd-even staggering in the charge distribution of the emitted fragments
N. L. Calleya, S. R. Souza, B. V. Carlson +4
The fragmentation of thermalized sources is studied using a version of the Statistical Multifragmentation Model which employs state densities that take the pairing gap in the nucle…
Thermodynamics of N-dimensional quantum walks
Alejandro Romanelli, Raul Donangelo, Renato Portugal +1
The entanglement between the position and coin state of a -dimensional quantum walker is shown to lead to a thermodynamic theory. The entropy, in this thermodynamics, is associa…
Rotation sets and almost periodic sequences
Tobias Jäger, Alejandro Passeggi, Sonja Štimac
We study the rotational behaviour on minimal sets of torus homeomorphisms and show that the associated rotation sets can be any type of line segments as well as non-convex and even…
