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 large deviation function of quantum heat engines
Tobias Denzler, Eric Lutz
The efficiency of small thermal machines is typically a fluctuating quantity. We here study the efficiency large deviation function of two exemplary quantum heat engines, the harmo…
Power fluctuations in a finite-time quantum Carnot engine
Tobias Denzler, Eric Lutz
Stability is an important property of small thermal machines with fluctuating power output. We here consider a finite-time quantum Carnot engine based on a degenerate multilevel sy…
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…
