Zero sound in a two-dimensional dipolar Fermi gas
Zhen-Kai Lu 1, S. I. Matveenko 2, 3, G. V. Shlyapnikov 2, 4, 5 Physical Review A 88 (2013) 033625 We study zero sound in a weakly interacting 2D gas of single-component fermionic dipoles (polar molecules or atoms with a large magnetic moment) tilted with respect to the plane of their translational motion. It is shown that the propagation of zero sound is provided

Wigner time-delay distribution in chaotic cavities and freezing transition
Christophe Texier 1, 2, Satya N. Majumdar 1 Physical Review Letters 110 (2013) 250602 Using the joint distribution for proper time-delays of a chaotic cavity derived by Brouwer, Frahm & Beenakker [Phys. Rev. Lett. {\bf 78}, 4737 (1997)], we obtain, in the limit of large number of channels $N$, the large deviation function for the distribution of the Wigner time-delay

Universality Classes of Critical Points in Constrained Glasses
Silvio Franz 1, Giorgio Parisi 2 Journal of Statistical Mechanics (2013) P11012 We analyze critical points that can be induced in glassy systems by the presence of constraints. These critical points are predicted by the Mean Field Thermodynamic approach and they are precursors of the standard glass transition in absence of constraints. Through a deep analysis of the soft

Two-point correlation function for Dirichlet L-functions
E Bogomolny 1,2 and J P Keating 3 J. Phys. A: Math. Theor. 46 (2013) 095202 (10pp) The two-point correlation function for the zeros of Dirichlet L-functions at a height E on the critical line is calculated heuristically using a generalization of the Hardy–Littlewood conjecture for pairs of primes in arithmetic progression. The result matches

Two-dimensional dipolar Bose gas with the roton-maxon excitation spectrum
Abdelâali Boudjemaâ 1, G. V. Shlyapnikov 2 Physical Review A 87 (2013) 025601 We discuss fluctuations in a dilute two-dimensional Bose-condensed dipolar gas, which has a roton-maxon character of the excitation spectrum. We calculate the density-density correlation function, fluctuation corrections to the chemical potential, compressibility, and the normal (superfluid) fraction. It is shown that the presence of the roton
