Laakso, M.A. (author), Heikkilä, T.T. (author), Nazarov, Y.V. (author)We describe the statistics of temperature fluctuations in a SINIS structure, where a normal metal island (N) is coupled by tunnel junctions (I) to two superconducting leads (S). We specify conditions under which this structure exhibits manifestly non-Gaussian fluctuations of temperature. We consider both the Gaussian and non-Gaussian regimes of...journal article 2012

Laakso, M.A. (author), Heikkilä, T.T. (author), Nazarov, Y.V. (author)We propose a mesoscopic setup which exhibits strong and manifestly non-Gaussian fluctuations of energy and temperature when suitably driven out of equilibrium. The setup consists of a normal metal island (N) coupled by tunnel junctions (I) to two superconducting leads (S), forming a SINIS structure, and is biased near the threshold voltage for...journal article 2012

Laakso, M.A. (author), Heikkilä, T.T. (author), Nazarov, Y.V. (author)Interplay of cotunneling and single-electron tunneling in a thermally isolated single-electron transistor leads to peculiar overheating effects. In particular, there is an interesting crossover interval where the competition between cotunneling and single-electron tunneling changes to the dominance of the latter. In this interval, the current...journal article 2010

Laakso, M.A. (author), Heikkilä, T.T. (author), Nazarov, Y.V. (author)We consider the fully overheated single-electron transistor, where the heat balance is determined entirely by electron transfers. We find three distinct transport regimes corresponding to cotunneling, single-electron tunneling, and a competition between the two. We find an anomalous sensitivity to temperature fluctuations at the crossover...journal article 2010
