Random walk diffusion simulations in semi-permeable layered media with varying diffusivity
Ignasi Alemany, Jan N. Rose, Jérôme Garnier-Brun +2
In this paper we present analytical and random walk based solutions to diffusion in semi-permeable layered media with varying diffusivity. We propose a new random walk transit mode…

A new spin on optimal portfolios and ecological equilibria
Jerome Garnier-Brun, Michael Benzaquen, Stefano Ciliberti +1
We consider the classical problem of optimal portfolio construction with the constraint that no short position is allowed, or equivalently the valid equilibria of multispecies Lotk…
