Anomalous diffusion in random media of any dimensionality (2008)

Bouchaud, J.P., Comtet, A., Georges, A., Le Doussal, P.

We show, through physical arguments and a renormalization group analysis, that in the presence of long-range correlated random forces, diffusions is anomalous in any dimension. We obtain in general...

The Dirac equation in Taub-NUT space (2005)

Comtet, A., Horvathy, P. A.

Using chiral supersymmetry, we show that the massless Dirac equation in the Taub-NUT gravitational instanton field is exactly soluble and explain the arisal and the use of the dynamical (super)...

Sample-size dependence of the ground-state energy in a one-dimensional localization problem (2005)

Multifractality in uniform hyperbolic lattices and in quasi-classical Liouville field theory (2000)
