Restoring heat and particle flow in strongly coupled non-equilibrium devices
Noa Ludwin, Ohad Cremerman, Milan Šindelka +1
Under non-equilibrium conditions, energy/particle currents flow through a quantum system coupled to multiple baths. Although the fluxes increase in the weak coupling regime as the…
Probing Non-equilibrium baths: Frequency-Resolved Thermometry and Quantum Heat Current Turnover
Akhil Bhartiya, Tobias Kramer, David Gelbwaser-Klimovsky
Quantum heat transport for non-equilibrium steady state (NESS) exhibits a characteristic turnover effect, where the heat current reaches a maximum and subsequently declines as syst…
A Contactless Heat Engine Driven by Nonreciprocal Fluctuation-Induced Torques
Dhruv Shah, Kiryl Asheichyk, David Gelbwaser-Klimovsky +3
We describe a contactless heat engine in which quantum and thermal electromagnetic fluctuations act as the working medium. The setup consists of two concentric cylinders held at di…
Steady state of periodically driven quantum systems
Milan Šindelka, David Gelbwaser-Klimovsky
Periodic driving is used to steer physical systems to unique stationary states or nonequilibrium steady states (NESS), producing enhanced properties inaccessible to non-driven syst…
Thermalization without detailed balance: population oscillations in the absence of coherences
Shay Blum, David Gelbwaser-Klimovsky
Open quantum systems that comply with the master equation and detailed balance decay in a non-oscillatory manner to thermal equilibrium. Beyond the weak coupling limit, systems tha…
On thermodynamic inconsistencies in several photosynthetic and solar cell models and how to fix them
David Gelbwaser-Klimovsky, Alán Aspuru-Guzik
We analyze standard theoretical models of solar energy conversion developed to study solar cells and photosynthetic systems. We show that the assumption that the energy transfer to…
Power enhancement of heat engines via correlated thermalization in multilevel systems
David Gelbwaser-Klimovsky, Wolfgang Niedenzu, Paul Brumer +1
We analyze a heat machine based on a periodically-driven quantum system permanently coupled to hot and cold baths. It is shown that the maximal power output of a degenerate -typ…
