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 […]

We first present a thorough study of the

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

Majumdar 2 Gregory Schehr 2 Pierre Le Doussal 1 Satya Majumdar 2 Physical Review Letters, American Physical Society, 2018, 121 (3), 〈10.1103/PhysRevLett.121.030603〉 We compute the joint statistics of the momenta $p_i$ of $N$ non-interacting fermions in a trap, near the Fermi edge, with a particular focus on the largest

Giovanni I. Martone 1 Pierre-Elie Larré 2 Alessandro Fabbri 3 Nicolas Pavloff 1 Phys.Rev.A, 2018, 98 (6), pp.063617. 〈10.1103/PhysRevA.98.063617〉 We consider a weakly interacting uniform atomic Bose gas with a time-dependent nonlinear coupling constant. By developing a suitable Bogoliubov treatment we investigate the time evolution of several observables, including the momentum distribution, the degree of

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

Thomas Barthel 1, 2 Caterina De Bacco 2, 3 Silvio Franz 2 Physical Review E , American Physical Society (APS), 2018, 97 (1), 〈10.1103/PhysRevE.97.010104〉 We introduce and apply a novel efficient method for the precise simulation of stochastic dynamical processes on locally tree-like graphs. Networks with cycles are treated in the framework of the cavity
