Fabio Deelan Cunden 1, 2 Pierpaolo Vivo 3 Physical Review Letters, American Physical Society, 2014, 113, pp.070202 We derive an analytical formula for the covariance $\mathrm{Cov}(A,B)$ of two smooth linear statistics $A=\sum_i a(\lambda_i)$ and $B=\sum_i b(\lambda_i)$ to leading order for $N\to\infty$, where $\{\lambda_i\}$ are the $N$ real eigenvalues of a general one-cut random-matrix model with […]

Mihailovic 1, 2, 5 Science, American Association for the Advancement of Science, 2014, 344, pp.177-180 Hidden states of matter with novel and unusual properties may be created if a system out of equilibrium can

Andrey Y. Lokhov 1 Olga V. Valba 2, 3 Sergei K. Nechaev 1, 4, 3 Mikhail V. Tamm 5, 3 Journal of Statistical Mechanics: Theory and Experiment, IOP Science, 2014, pp.P12004 In this paper, we investigate analytically the properties of the disordered Bernoulli model of planar matching. This model is characterized by a topological phase

Satya N. Majumdar 1 Gregory Schehr 1 Journal of Statistical Mechanics: Theory and Experiment, IOP Science, 2014, pp.P01012 We study the fluctuations of the largest eigenvalue $\lambda_{\max}$ of $N \times N$ random matrices in the limit of large $N$. The main focus is on Gaussian $\beta$-ensembles, including in particular the Gaussian orthogonal ($\beta=1$), unitary ($\beta=2$)

D. S. Petrov 1 Physical Review Letters, American Physical Society, 2014, 112, pp.103201 We propose a method of controlling two- and three-body interactions in an ultracold Bose gas in any dimension. The method requires us to have two coupled internal single-particle states split in energy such that the upper state is occupied virtually but amply

Stephane Ouvry 1 Leonid Pastur 2 Andrey Yanovsky 2 Europhysics Letters, EDP Science, 2014, 106, pp.18001 We consider T-invariant spin currents induced by spin-orbit interactions which originate from the confined motion of spin carriers in nanostructures. The resulting Thomas spin precession is a fundamental and purely kinematic relativistic effect occurring when the acceleration of carriers

Dario Villamaina 1 Emmanuel Trizac 1 European Journal of Physics, Institute of Physics: Hybrid Open Access, 2014, 35, pp.3 The isothermal compressibility of an interacting or non interacting system may be extracted from the fluctuations of the number of particles in a well chosen control volume. Finite size effects are prevalent and should then be

Martin 4 Physical Review Letters, American Physical Society, 2014, 112, pp.234101. <10.1103/PhysRevLett.112.234101> We expose two scenarios for the breakdown of quantum multifractality under the effect of perturbations. In the first scenario, multifractality survives below a certain scale of the

Huang Bo 1 O’Hara Kenneth M. 2, 3 Grimm Rudolf 1, 3 Hutson Jeremy M. 4 Petrov Dmitry S. 5 Physical Review A, American Physical Society, 2014, 90, pp.043636 We present a state-of-the-art reanalysis of experimental results on Efimov resonances in the three-fermion system of $^6$Li. We discuss different definitions of the 3-body parameter (3BP)
