Self-repellent Brownian Bridges in an Interacting Bose Gas

Erwin Bolthausen, Wolfgang Koenig, Chiranjib Mukherjee

We consider a model of $d$ -dimensional interacting quantum Bose gas, expressed in terms of an ensemble of interacting Brownian bridges in a large box and undergoing the influence o…

Long-time tails in the parabolic Anderson model with bounded potential

Marek Biskup, Wolfgang Koenig

We consider the parabolic Anderson problem $\partial_{t} u = κ Δ u + ξ u$ on $(0, \infty) \times Z^{d}$ with random i.i.d. potential $ξ = (ξ (z))_{z \in Z^{d}}$ and the initial condition $u(0,\cdot)…
