Aurélien Grabsch 1 Satya N. Majumdar 1 Christophe Texier 1 Journal of Statistical Physics, Springer Verlag, 2017, 167 (6), pp.1452 – 1488 Invariant ensembles of random matrices are characterized by the distribution of their eigenvalues $\{\lambda_1,\cdots,\lambda_N\}$. We study the distribution of truncated linear statistics of the form $\tilde{L}=\sum_{i=1}^p f(\lambda_i)$ with $p 1. LPTMS – Laboratoire […]

Damjan Svetin 1 Igor Vaskivskyi 2 Serguei Brazovskii 3 Dragan Mihailovic 4, 1, 2 Scientific Reports, Nature Publishing Group, 2017, 7, pp.46048 Recent demonstrations of controlled switching between different ordered macroscopic states by impulsive electromagnetic perturbations in complex materials have opened some fundamental questions on the mechanisms responsible for such remarkable behavior. Here we experimentally

We

Thorsten Emig 1, 2 Physical Review E , American Physical Society (APS), 2017, 95 (5), pp.052104 We analyze the equilibrium spatial distribution of surface temperatures of patterned surfaces. The surface is exposed to a constant external heat flux and has a fixed internal temperature that is coupled to the outside heat fluxes by finite heat

We show that for large N, the correlations at the edge of the Fermi gas (near the wall) at zero temperature

Bertrand Lacroix-A-Chez-Toine 1 Pierre Le Doussal 2 Satya N. Majumdar 1 Gregory Schehr 1 EPL – Europhysics Letters, European Physical Society/EDP Sciences/Società Italiana di Fisica/IOP Publishing, 2017 We study $N$ noninteracting fermions in a domain bounded by a hard wall potential in $d \geq 1$ dimensions. We show that for large $N$, the correlations at
