Silvio Franz 1, Giorgio Parisi 2, Federico Ricci-Tersenghi 2, Tommaso Rizzo 2 The European Physical Journal E 34 (2011) 102 We develop a field-theoretical description of dynamical heterogeneities and fluctuations in supercooled liquids close to the (avoided) MCT singularity. Using quasi-equilibrium arguments we eliminate time from the description and we completely characterize fluctuations in the beta regime. We identify different sources of fluctuations

Giuliano Orso 1, Evgeni Burovski 2, Thierry Jolicoeur 2 Comptes Rendus Physique 12 (2011) 39-46 We investigate the formation of three-body bound states (trimers) in two-component Fermi gases confined in one dimensional optical lattice with spin-dependent tunneling rates. The binding energy and the effective mass of the trimer are obtained from the solution of the Mattis integral equation generalized to the

Michele Castellana 1, 2, Aurelien Decelle 1, Elia Zarinelli 1 Physical Review Letters 107 (2011) 275701 We study the probability distribution of the pseudo-critical temperature in a mean-field and in a short-range spin-glass model: the Sherrington-Kirkpatrick (SK) and the Edwards-Anderson (EA) model. In both cases, we put in evidence the underlying connection between the fluctuations of the pseudo-critical point and and the

Alain Comtet 1, 2, Yves Tourigny 3 Annales de l’Institut Henri Poincaré (B) Probabilités et Statistiques 47 (2011) 850-874 It is well-known that the excursions of a one-dimensional diffusion process can be studied by considering a certain Riccati equation associated with the process. We show that, in many cases of interest, the Riccati equation can be solved in terms of

M. Mezard 1, J. Sakellariou 1 Journal of statistical mechanics-theory and experiment (2011) L07001 We develop an elementary mean field approach for fully asymmetric kinetic Ising models, which can be applied to a single instance of the problem. In the case of the asymmetric SK model this method gives the exact values of the local magnetizations and the exact

Areejit Samal 1, 2, Andreas Wagner 3, 4, 5, Olivier C. Martin 2, 6 BMC Systems Biology 5 (2011) 135 The ubiquity of modules in biological networks may result from an evolutionary benefit of a modular organization. For instance, modularity may increase the rate of adaptive evolution, because modules can be easily combined into new arrangements that may benefit their carrier. Conversely, modularity may emerge

P. Maynar 1, E. Trizac 2 Physical Review Letters 106 (2011) 160603 In its continuous version, the entropy functional measuring the information content of a given probability density may be plagued by a ‘measure’ problem that results from improper weighting of phase space. This issue is addressed considering a generic collision process whereby a large number of particles/agents randomly

Noah Graham 1, Alexander Shpunt 2, Thorsten Emig 3, Sahand Jamal Rahi 2, 4, Robert L. Jaffe 2, Mehran Kardar 2 Physical Review D 83 (2011) 125007 An exact calculation of electromagnetic scattering from a perfectly conducting parabolic cylinder is employed to compute Casimir forces in several configurations. These include interactions between a parabolic cylinder and a plane, two parabolic cylinders, and a parabolic cylinder and an ordinary
