Calorimetric measurement of quantum work
Jukka P. Pekola, Paolo Solinas, Alexander Shnirman +1
To define the work performed on a driven quantum system in a physically sound way has turned out to be a truly non-trivial task, except in some special cases of limited applicabili…
Heat transport through a Josephson junction
Dmitry Golubev, Timothé Faivre, Jukka P. Pekola
We discuss heat transport through a Josephson tunnel junction under various bias conditions. We first derive the formula for the cooling power of the junction valid for arbitrary t…
Environment-governed dynamics in driven quantum systems
S. Gasparinetti, P. Solinas, S. Pugnetti +2
We show that the dynamics of a driven quantum system weakly coupled to the environment can exhibit two distinct regimes. While the relaxation basis is usually determined by the sys…
Single-electron current sources: towards a refined definition of ampere
J. P. Pekola, O. -P. Saira, V. F. Maisi +4
Controlling electrons at the level of elementary charge has been demonstrated experimentally already in the 1980's. Ever since, producing an electrical current , or its int…
Test of Jarzynski and Crooks fluctuation relations in an electronic system
O. -P. Saira, Y. Yoon, T. Tanttu +3
Recent progress on micro- and nanometer scale manipulation has opened the possibility to probe systems small enough that thermal fluctuations of energy and coordinate variables can…
Work and its fluctuations in a driven quantum system
Paolo Solinas, Dmitri V. Averin, Jukka P. Pekola
We analyze work done on a quantum system driven by a control field. The average work depends on the whole dynamics of the system, and is obtained as the integral of the average pow…
