Revisiting Directed Polymers with heavy-tailed disorder
Thomas Gueudré, Pierre Le Doussal, Jean-Philippe Bouchaud +1
In this mostly numerical study, we revisit the statistical properties of the ground state of a directed polymer in a "hilly" disorder landscape, i.e. when the quenched diso…
Strong pinning of propagation fronts in adverse flow
Thomas Gueudré, Awadhesh Kumar Dubey, Laurent Talon +1
Reaction fronts evolving in a porous medium exhibit a rich dynamical behaviour. In presence of an adverse flow, experiments show that the front slows down and eventually gets pinne…
Statistics of shocks in a toy model with heavy tails
Thomas Gueudré, Pierre Le Doussal
We study the energy minimization for a particle in a quadratic well in presence of short-ranged heavy-tailed disorder, as a toy model for an elastic manifold. The discrete model is…
Explore or exploit? A generic model and an exactly solvable case
Thomas Gueudré, Alexander Dobrinevski, Jean-Philippe Bouchaud
Finding a good compromise between the exploitation of known resources and the exploration of unknown, but potentially more profitable choices, is a general problem, which arises in…
Directed polymer near a hard wall and KPZ equation in the half-space
Thomas Gueudre, Pierre Le Doussal
We study the directed polymer with fixed endpoints near an absorbing wall, in the continuum and in presence of disorder, equivalent to the KPZ equation on the half space with dropl…
