Trophée Tangente 2017

Notre collègue Hubert Krivine vient de recevoir une mention au « Trophée Tangente », décerné par magazine Tangente, pour son livre « Petit traité de hasardologie » (Éditions Cassini). Le Trophée Tangente vise « à promouvoir les mathématiques culturelles et les rendre accessibles au plus grand nombre ».

Hall voltage drives pulsing counter-currents of the sliding charge density wave and of quantized normal carriers at self-filled Landau levels

The journal Nature Quantum Materials has just published [1] an article presented by an international team from the Neel Institute in Grenoble – France, LPTMS-CNRS and the University Paris-Sud Saclay at Orsay – France and the Institute for Radioengenering and Electronics in Moscow – Russia. The article is entitled “Hall voltage drives pulsing counter-currents of …

What drives transient behavior in complex systems?

Jacek Grela 1 Phys.Rev.E, 2017, 96 (2), pp.022316. 〈10.1103/PhysRevE.96.022316〉 We study transient behavior in the dynamics of complex systems described by a set of nonlinear ordinary differential equations. Destabilizing nature of transient trajectories is discussed and its connection with the eigenvalue-based linearization procedure. The complexity is realized as a random matrix drawn from a modified …

Universality of the SAT-UNSAT (jamming) threshold in non-convex continuous constraint satisfaction problems

Pierfrancesco Urbani 1 Francesco Zamponi 2 Silvio Franz 3 Giorgio Parisi 4 Maksim Sevelev 3 SciPost Physics, 2017, 2 (3), pp.019 Random constraint satisfaction problems (CSP) have been studied extensively using statistical physics techniques. They provide a benchmark to study average case scenarios instead of the worst case one. The interplay between statistical physics of …

Two-body relaxation of spin-polarized fermions in reduced dimensionalities near a p-wave Feshbach resonance

D. V. Kurlov 1 G. V. Shlyapnikov 2 Physical Review A, American Physical Society, 2017, 95 (3), pp.032710 We study inelastic two-body relaxation in a spin-polarized ultracold Fermi gas in the presence of a p-wave Feshbach resonance. It is shown that in reduced dimensionalities, especially in the quasi-one-dimensional case, the enhancement of the inelastic rate …

Two- and three-body problem with Floquet-driven zero-range interactions

A. G. Sykes 1 H. Landa 1 D. S. Petrov 1 Physical Review A, American Physical Society, 2017, 95 (6), pp.062705 We study the two-body scattering problem in the zero-range approximation with a sinusoidally driven scattering length and calculate the relation between the mean value and amplitude of the drive for which the effective scattering …

Truncated linear statistics associated with the top eigenvalues of random matrices

Aurélien Grabsch 1 Satya N. Majumdar 1 Christophe Texier 1 Journal of Statistical Physics, Springer Verlag, 2017, 167 (2), pp.234 – 259 Given a certain invariant random matrix ensemble characterised by the joint probability distribution of eigenvalues $P(\lambda_1,\cdots,\lambda_N)$, many important questions have been related to the study of linear statistics of eigenvalues $L=\sum_{i=1}^Nf(\lambda_i)$, where $f(\lambda)$ …
