Discrete thermodynamic Bethe ansatz
Michel Bergere 1, Ken-Ichiro Imura 2, Stéphane Ouvry 2 Nuclear Physics B 608 (2001) 577 We propose discrete TBA equations for models with discrete spectrum. We illustrate our construction on the Calogero-Moser model and determine the discrete 2-body TBA function which yields the exact N-body Calogero-Moser thermodynamics. We apply this algorithm to the Lieb-Liniger model in a harmonic well, a model

Discrete energy landscapes and replica symmetry breaking at zero temperature
Florent Krzakala 1, Olivier C. Martin 1 Europhysics Letters (EPL) 53 (2001) 749-755 The order parameter P(q) for disordered systems with degenerate ground-states is reconsidered. We propose that entropy fluctuations lead to a trivial P(q) at zero temperature as in the non-degenerate case, even if there are zero-energy large-scale excitations (complex energy landscape). Such a situation should arise in the

Classification of Conformal Field Theories Based on Coulomb gases. Application to Loop Models
Vladimir S. Dotsenko 1, Jesper Lykke Jacobsen 2, Marco Picco 1 Nuclear Physics B 618 (2001) 523 We present a method for classifying conformal field theories based on Coulomb gases (bosonic free-field construction). Given a particular geometric configuration of the screening charges, we give necessary conditions for the existence of degenerate representations and for the closure of the vertex-operator algebra. The resulting classification

Bose beams: coherent propagation through a guide
Patricio Leboeuf 1, Nicolas Pavloff 1 Physical Review A: Atomic, Molecular and Optical Physics 64 (2001) 033602 We compute the stationary profiles of a coherent beam of Bose condensed atoms propagating through a guide. Special emphasis is put on the effect of an obstacle present on the trajectory of the beam. The obstacle considered (such as a bend in

Adsorption of a random heteropolymer at a potential well revisited: location of transition point and design of sequences
Alexei A. Naidenov 1, Sergei K. Nechaev 1, 2 Journal of Physics A 34 (2001) 5625-5634 The adsorption of an ideal heteropolymer loop at a potential point well is investigated within the frameworks of a standard random matrix theory. On the basis of semi-analytical/semi-numerical approach the histogram of transition points for the ensemble of quenched heteropolymer structures with bimodal symmetric distribution of
