Martina Hentschel 1, 2, Denis Ullmo 1, 3, Harold U. Baranger 1 Physical Review B 72 (2005) 035310 For generic mesoscopic systems like quantum dots or nanoparticles, we study the Anderson orthogonality catastrophe (AOC) and Fermi edge singularities in photoabsorption spectra in a series of two papers. In the present paper we focus on AOC for a finite number of particles in discrete energy […]

A. Minguzzi 1, D. M. Gangardt 1 Physical Review Letters 94 (2005) 240404 Using a scaling transformation we exactly determine the dynamics of an harmonically confined Tonks-Girardeau gas under arbitrary time variations of the trap frequency. We show how during a one-dimensional expansion a « dynamical fermionization\’\’ occurs as the momentum distribution rapidly approaches an ideal Fermi gas distribution, and

Satya Majumdar 1, Sergei K. Nechaev 1, 2 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 72 (2005) 020901 Finding analytically the statistics of the longest common subsequence (LCS) of a pair of random sequences drawn from c alphabets is a challenging problem in computational evolutionary biology. We present exact asymptotic results for the distribution of the LCS in a

The susceptibility can be measured by

D. S. Petrov 1, C. Salomon 2, G. V. Shlyapnikov 3, 4 Journal of Physics B 38 (2005) S645-S660 We give a brief overview of recent studies of weakly bound homonuclear molecules in ultracold two-component Fermi gases. It is emphasized that they represent novel composite bosons, which exhibit features of Fermi statistics at short intermolecular distances. In particular, Pauli exclusion principle for

Christophe Texier 1, 2, Gilles Montambaux 2 Physical Review B 72 (2005) 115327 We study the effect of the electron-electron interaction on the weak localization correction of a ring pierced by a magnetic flux. We compute exactly the path integral giving the magnetoconductivity for an isolated ring. The results are interpreted in a time representation. This allows to characterize the
