Roughness of a tilted anharmonic string at depinning
Roughness of a tilted anharmonic string at depinning
We consider the discretized model of a driven string with an anharmonic elastic energy, in a two-dimensional random potential, as introduced by [Rosso and Krauth, Phys. Rev. Lett. 87, 187002 (2001)]. Using finite size scaling, we numerically compute the roughness of the string in a uniform applied force at the …
