Universality and quantization of the power-to-heat ratio in nanogranular systems

N. M. Chtchelkatchev (Landau Institute, Moscow)

par Gabriel LeMarié - 8 juillet 2014

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.
