Geometry-induced localization of thermal fluctuations in ultrathin superconducting structures
arXiv:1009.0590 · doi:10.1103/PhysRevB.82.054523
Abstract
Thermal fluctuations of the order parameter in an ultrathin triangular shaped superconducting structure are studied near , in zero applied field. We find that the order parameter is prone to much larger fluctuations in the corners of the structure as compared to its interior. This geometry-induced localization of thermal fluctuations is attributed to the fact that condensate confinement in the corners is characterised by a lower effective dimensionality, which favors stronger fluctuations.
