A. Iu. Gudyma 1 G. E. Astrakharchik 2 Mikhail B. Zvonarev 1 Physical Review A, American Physical Society, 2015, 92, pp.021601 We calculate the breathing mode frequency $\omega$ in a one-dimensional Bose gas confined to a harmonic trap of frequency $\omega_z$. We predict Exciting temporal oscillations of the density distribution is a high-precision method for […]

Claude Godreche 1 Satya N. Majumdar 2 Gregory Schehr 2 Journal of Statistical Mechanics: Theory and Experiment, IOP Science, 2015 We investigate the statistics of records in a random sequence $\{x_B(0)=0,x_B(1),\cdots, x_B(n)=x_B(0)=0\}$ of $n$ time steps. The sequence $x_B(k)$’s represents the position at step $k$ of a random walk `bridge’ of $n$ steps that starts

Satya N. Majumdar 1 Sanjib Sabhapandit 2 Gregory Schehr 1 Physical Review E : Statistical, Nonlinear, and Soft Matter Physics, American Physical Society, 2015, 92, pp.052126 We study analytically a simple random walk model on a one-dimensional lattice, where at each time step the walker resets to the maximum of the already visited positions (to

Pasquale Calabrese 1 Pierre Le Doussal 2 Satya N. Majumdar 3 Physical Review A, American Physical Society, 2015, pp.012303 We exploit and clarify the use of random matrix theory for the calculation of the entanglement entropy of free Fermi gases. We apply this method to obtain analytic predictions for Renyi entanglement entropies of a one-dimensional

Pablo Rodriguez-Lopez 1 Wang-Kong Tse 2 Diego A. R. Dalvit 2 Journal of Physics: Condensed Matter, Institute of Physics: Hybrid Open Access, 2015, 27, pp.214019 We compute the radiative heat transfer between two sheets of 2D Dirac materials, including topological Chern insulators and graphene, within the framework of the local approximation for the optical response

Silvio Franz 1 Giorgio Parisi 2 Pierfrancesco Urbani 3, 1 Journal of Physics A: Mathematical and Theoretical, IOP Publishing, 2015, 48, pp.19FT01 We introduce a quasi-equilibrium formalism in the theory of liquids in order to obtain a set of coarse grained long time dynamical equations for the two point density correlation functions. Our scheme allows

Silvio Franz 1 Giorgio Parisi 2 Federico Ricci-Tersenghi 2 Pierfrancesco Urbani 3 Journal of Statistical Mechanics: Theory and Experiment, IOP Publishing, 2015, pp.P10010 In this paper we review a recent proposal to understand the long time limit of glassy dynamics in terms of an appropriate Markov Chain. [1]. The advantages of the resulting construction are

Westbrook 1 Pawel Zin 5 Physical Review Letters., 2015, 115 (2), pp.025301. <http://journals.aps.org/prl/>. <10.1103/PhysRevLett.115.025301> We consider a sonic analog of a black hole realized in the one-dimensional flow of a Bose-Einstein condensate. Our theoretical analysis demonstrates that one- and two-body momentum

D. S. Petrov 1 Physical Review Letters, American Physical Society, 2015, 115, pp.155302 According to the mean-field theory a condensed Bose-Bose mixture collapses when the interspecies attraction becomes stronger than the geometrical average of the intraspecies repulsions, $g_{12}^2>g_{11} g_{22}$. We show that instead of collapsing such a mixture gets into a dilute liquid-like droplet state

Kiryl Pakrouski 1 Michael R. Peterson 2 Thierry Jolicoeur 3 Vito W. Scarola 4 Chetan Nayak 5, 6 Matthias Troyer 1 Physical Review X, American Physical Society, 2015, 5, pp.029901 Interesting non-Abelian states, e.g., the Moore-Read Pfaffian and the anti-Pfaffian, offer candidate descriptions of the $\nu = 5/2$ fractional quantum Hall state. But the significant
