Enhancing the power of a quantum heat engine via control of the system--reservoir coupling
Sabrina Burgardt, Julian Feß, Silvia Hiebel +2
The non-equilibrium properties of open quantum systems are determined by the microscopic laws governing energy exchange with their environment. In particular, an enhancement of the…
Correlated quantum machines beyond the standard second law
Milton Aguilar, Eric Lutz
The laws of thermodynamics strongly restrict the performance of thermal machines. Standard thermodynamics, initially developed for uncorrelated macroscopic systems, does not hold f…
Far-from-equilibrium thermodynamics of non-Abelian thermal states
Franklin L. S. Rodrigues, Eric Lutz
Noncommutativity of observables is a central feature of quantum physics. It plays a fundamental role in the formulation of the uncertainty principle for complementary variables and…
Power-efficiency-stability trade-off in quantum information engines
Milton Aguilar, Cüneyt Ãnal, Eric Lutz
Efficiency and power are two central measures of the performance of thermal machines. We here study the power-efficiency-stability trade-off in a finite-time quantum Carnot informa…
Nonadiabatic master equation for a linearly driven harmonic oscillator
Sinan Altinisik, Eric Lutz
We derive a Markovian master equation for a linearly driven dissipative quantum harmonic oscillator, valid for generic driving beyond the adiabatic limit. We solve this quantum mas…
A many-particle bosonic quantum Maxwell demon
Josef HlouÅ¡ek, Tobias Denzler, VojtÄch Å varc +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…
