Logotropic distributions
Pierre-Henri Chavanis, Clement Sire
In all spatial dimensions , we study the static and dynamical properties of a generalized Smoluchowski equation which describes the evolution of a gas obeying a logotropic equat…
Probability distribution of the maximum of a smooth temporal signal
Clément Sire
We present an approximate calculation for the distribution of the maximum of a smooth stationary temporal signal X(t). As an application, we compute the persistence exponent associ…
Exact solution of a model of time-dependent evolutionary dynamics in a rugged fitness landscape
Clement Sire, Satya N. Majumdar, David S. Dean
A simplified form of the time dependent evolutionary dynamics of a quasispecies model with a rugged fitness landscape is solved via a mapping onto a random flux model whose asympto…
Distance traveled by random walkers before absorption in a random medium
David S. Dean, Clément Sire, Julien Sopik
We consider the penetration length of random walkers diffusing in a medium of perfect or imperfect absorbers of number density . We solve this problem on a lattice and in th…
