Converting coherence into work with a fully quantum engine
MinSik Kwon, Tobias Denzler, Rouven Maier +4
Heat engines convert thermal energy into mechanical work. We here report the experimental realization of a fully quantum engine that converts quantum coherence into work. A single…
A many-particle bosonic quantum Maxwell demon
Josef Hloušek, Tobias Denzler, Vojtěch Švarc +3
Energy extraction from a measured quantum system is a cornerstone of information thermodynamics as illustrated by Maxwell's demon. The nonequilibrium physics of many-particle syste…
Nonequilibrium fluctuations of a quantum heat engine
Tobias Denzler, Jonas F. G. Santos, Eric Lutz +1
The thermodynamic properties of quantum heat engines are stochastic owing to the presence of thermal and quantum fluctuations. We here experimentally investigate the efficiency and…
Efficiency fluctuations of a quantum Otto engine
Tobias Denzler, Eric Lutz
We derive the probability distribution of the efficiency of a quantum Otto engine. We explicitly compute the quantum efficiency statistics for an analytically solvable two-level en…
Heat distribution of a quantum harmonic oscillator
Tobias Denzler, Eric Lutz
We consider a thermal quantum harmonic oscillator weakly coupled to a heat bath at a different temperature. We analytically study the quantum heat exchange statistics between the t…
