Xiangyu Cao 1 Vincent Démery 2, 3 Alberto Rosso 4, 5 Journal of Physics A: Mathematical and Theoretical, IOP Publishing, 2018, 51 (23), 〈10.1088/1751-8121/aac02f〉 The existence of a depinning transition for a high dimensional interface in a weakly disordered medium is controversial. Following Larkin arguments and a perturbative expansion, one expects a linear response with […]

V. Roberdel 1 D. Leibfried 2 D. Ullmo 1 H. Landa 1, 3 Physical Review A, American Physical Society, 2018, 97 (5), 〈10.1103/PhysRevA.97.053419〉 We present a comprehensive phase-space treatment of the motion of charged particles in electrodynamic traps. Focusing on five-wire surface-electrode Paul traps, we study the details of integrable and chaotic motion of a

Alexandre Nicolas 1 Ioannis Touloupas 1 Journal of Statistical Mechanics, 2018, 1, pp.013402. 〈http://iopscience.iop.org/article/10.1088/1742-5468/aa9dcd〉 Robust statistical features have emerged from the microscopic analysis of dense pedestrian flows through a bottleneck, notably with respect to the time gaps between successive passages. We pinpoint the mechanisms at the origin of these features thanks to simple models that

Xiangyu CaoPierre Le Doussal 1 Alberto Rosso 2 Raoul Santachiara 2 Phys.Rev.E, 2018, 97 (4), pp.042111. 〈10.1103/PhysRevE.97.042111〉 We study transitions in log-correlated random energy models (logREMs) that are related to the violation of a Seiberg bound in Liouville field theory (LFT): the binding transition and the termination point transition (a.k.a., pre-freezing). By means of LFT-logREM

Relation to a recently studied statistics of bi-orthogonal eigenvectors in the complex

Christophe Texier 1, 2 Johannes Mitscherling 1, 3 Physical Review B : Condensed matter and materials physics, American Physical Society, 2018, 〈10.02214〉 We study the non-linear conductance $\mathcal{G}\sim\partial^2I/\partial V^2|_{V=0}$ in coherent quasi-1D weakly disordered metallic wires. The analysis is based on the calculation of two fundamental correlators (correlations of conductance’s functional derivatives and correlations of

Amit Kumar Chatterjee 1 Urna Basu 2 P. K. Mohanty 1 Physical Review E , American Physical Society (APS), 2018 Driven particles in presence of crowded environment, obstacles or kinetic constraints often exhibit negative differential mobility (NDM) due to their decreased dynamical activity. We propose a new mechanism for complex many-particle systems where slowing down

A. Fabbri 1 N. Pavloff 2 SciPost Phys., 2018, 4, pp.019. 〈10.21468/SciPostPhys.4.4.019〉 We study the two-body momentum correlation signal in a quasi one dimensional Bose-Einstein condensate in the presence of a sonic horizon. We identify the relevant correlation lines in momentum space and compute the intensity of the corresponding signal. We consider a set of

Petr Karpov 1 Serguei Brazovskii 2, 1, 3 Scientific Reports, Nature Publishing Group, 2018 Experiments on optical and STM injection of carriers in layered $\mathrm{MX_2}$ materials revealed the formation of nanoscale patterns with networks and globules of domain walls. This is thought to be responsible for the metallization transition of the Mott insulator and for

V. Crépel 1 B. Estienne 2 B.A. Bernevig 1, 3 P. Lecheminant 4 N. Regnault 1 Phys.Rev.B, 2018, 97 (16), pp.165136. 〈10.1103/PhysRevB.97.165136〉 Many fractional quantum Hall states can be expressed as a correlator of a given conformal field theory used to describe their edge physics. As a consequence, these states admit an economical representation as
