Depinning transition of a directed polymer by a periodic potential: a d-dimensional solution
S. Galluccio, R. Graber
We study the depinning phase transition of a directed polymer in a -dimensional space by a periodic potential localized on a straight line. We give exact formulas in all dimensi…

Diffusion on a hypercubic lattice with pinning potential: exact results for the error-catastrophe problem in biological evolution
S. Galluccio, R. Graber, Y. -C. Zhang
In the theoretical biology framework one fundamental problem is the so-called error catastrophe in Darwinian evolution models. We reexamine Eigen's fundamental equations by mapping…
