Universality and quantization of the power to heat ratio in nano-granular systems
arXiv:1307.6138 · doi:10.1103/PhysRevB.88.125130
Abstract
We study heating and dissipation effects in granular nanosystems in the regime of weak coupling between the grains. We focus on the cotunneling regime and solve the heat-dissipation problem in an array of grains exactly. We show that the power to heat ratio has a universal quantized value, which is geometrically protected: it depends only on the number of grains.
