Nanoscale quantum calorimetry with electronic temperature fluctuations

Brange, Fredrik LU ; Samuelsson, Peter LU ; Karimi, Bayan and Pekola, Jukka P. (2018) In Physical Review B - Condensed Matter and Materials Physics 98.
Abstract
Motivated by the recent development of fast and ultrasensitive thermometry in nanoscale systems, we investigate quantum calorimetric detection of individual heat pulses in the sub-meV energy range. We propose a hybrid superconducting injector-calorimeter setup, with the energy of injected pulses carried by tunneling electrons. It is shown that the superconductor constitutes a versatile injector, with tunable tunnel rates and energies. Treating all heat transfer events microscopically, we analyze the statistics of the calorimeter temperature fluctuations and derive conditions for an accurate measurement of the heat pulse energies. Our results pave the way for fundamental quantum thermodynamics experiments, including calorimetric detection... (More)
