Patricio Leboeuf 1, Alejandro Monastra 2 Nuclear Physics A 724 (2003) 69-84 We investigate the thermodynamics of a Fermi gas whose single-particle energy levels are given by the complex zeros of the Riemann zeta function. This is a model for a gas, and in particular for an atomic nucleus, with an underlying fully chaotic classical dynamics. The probability distributions

Denis Ullmo 1, 2, Tatsuro Nagano 3, Steven Tomsovic 3 Physical Review Letters 90 (2003) 176801 We consider how the nature of the dynamics affects ground state properties of ballistic quantum dots. We find that « mesoscopic Stoner fluctuations », that arise from the residual screened Coulomb interaction, are very sensitive to the degree of chaos. It leads to ground state energies and spin-polarizations

Serguei Brasovskii 1, Sergey I. Matveenko 1, 2 JETP Letters 96 (2003) 555 We consider pseudogap effects for electrons interacting with gapless modes. We study both generic 1D semiconductors with acoustic phonons and incommensurate charge density waves. We calculate the subgap absorption as it can be observed by means of the photo electron or tunneling spectroscopy. Within the formalism of functional

Matteo Palassini 1, Marta Sales 2, Felix Ritort 3 Physical Review B 68 (2003) 224430 We present a numerical study of the order-parameter fluctuations for Ising spin glasses in three and four dimensions at very low temperatures and without an external field. Accurate measurements of two previously introduced parameters, A and G, show that the order parameter is not self-averaging, consistent
