Propagation in a thermal graviton background
Daniel Arteaga, Renaud Parentani, Enric Verdaguer
It is well known that radiative corrections evaluated in nontrivial backgrounds lead to effective dispersion relations which are not Lorentz invariant. Since gravitational interact…
Random Matrices and the Anderson Model
M. Disertori, V. Rivasseau
In recent years,constructive field techniques and the method of renormalization group around extended singularities have been applied to the weak coupling regime of the Anderson Mo…
The Diffusion Equation on a Hypersphere
J. -M. Caillol
We study the diffusion equation on the surface of a 4D sphere and obtain a Kubo formula for the diffusion coefficient.
On Conservative and Monotone One-dimensional Cellular Automata and Their Particle Representation
Andres Moreira, Nino Boccara, Eric Goles
Number-conserving (or {\em conservative}) cellular automata have been used in several contexts, in particular traffic models, where it is natural to think about them as systems of…
Determination of the exchange energies in Li2VOSiO4 from a high-temperature series analysis of the square lattice J1-J2 Heisenberg model
G. Misguich, B. Bernu, L. Pierre
We present a high-temperature expansion (HTE) of the magnetic susceptibility and specific heat data of Melzi et al. on Li2VOSiO4 [Phys. Rev. B 64, 024409 (2001)]. The data are very…
