Lee-Yang theory of Bose-Einstein condensation
Fredrik Brange, Tuomas Pyhäranta, Eppu Heinonen +2
Bose-Einstein condensation happens as a gas of bosons is cooled below its transition temperature, and the ground state becomes macroscopically occupied. The phase transition occurs…
Thermodynamic geometry of ideal quantum gases: a general framework and a geometric picture of BEC-enhanced heat engines
Joshua Eglinton, Tuomas Pyharanta, Keiji Saito +1
Thermodynamic geometry provides a physically transparent framework to describe thermodynamic processes in meso- and micro-scale systems that are driven by slow variations of extern…
Fluctuations of Heat in Driven Two-State Systems: Application to Single-Electron Box with Superconducting Gap
Tuomas Pyhäranta, Luca Peliti, Jukka P. Pekola
We use trajectory averaging to show that the energy dissipated in the nonequilibrium energy-state transitions of a driven two-state system satisfies a fluctuation-dissipation relat…
Ultimate accuracy of frequency to power conversion by single-electron injection
Jukka P. Pekola, Marco Marín-Suárez, Tuomas Pyhäranta +1
We analyze theoretically the properties of the recently introduced and experimentally demonstrated converter of frequency to power. The system is composed of a hybrid single-electr…
Correlation-Enabled Energy Exchange in Quantum Systems without External Driving
T. Pyhäranta, S. Alipour, A. T. Rezakhani +1
We study the role of correlation in mechanisms of energy exchange between an interacting bipartite quantum system and its environment by decomposing the energy of the system to loc…
Two-Stroke Optimization Scheme for Mesoscopic Refrigerators
Paul Menczel, Tuomas Pyhäranta, Christian Flindt +1
Refrigerators use a thermodynamic cycle to move thermal energy from a cold reservoir to a hot one. Implementing this operation principle with mesoscopic components has recently eme…
