The quantum harmonic Otto cycle

R Kosloff, Y Rezek - Entropy, 2017 - mdpi.com
The quantum Otto cycle serves as a bridge between the macroscopic world of heat engines
and the quantum regime of thermal devices composed from a single element. We compile …

Colloquium: Quantum fluctuation relations: Foundations and applications

M Campisi, P Hänggi, P Talkner - Reviews of Modern Physics, 2011 - APS
Two fundamental ingredients play a decisive role in the foundation of fluctuation relations:
the principle of microreversibility and the fact that thermal equilibrium is described by the …

[HTML][HTML] Quantum thermodynamic devices: From theoretical proposals to experimental reality

NM Myers, O Abah, S Deffner - AVS quantum science, 2022 - pubs.aip.org
Thermodynamics originated in the need to understand novel technologies developed by the
Industrial Revolution. However, over the centuries, the description of engines, refrigerators …

Nanoscale heat engine beyond the Carnot limit

J Roßnagel, O Abah, F Schmidt-Kaler, K Singer, E Lutz - Physical review letters, 2014 - APS
We consider a quantum Otto cycle for a time-dependent harmonic oscillator coupled to a
squeezed thermal reservoir. We show that the efficiency at maximum power increases with …

Single-ion heat engine at maximum power

O Abah, J Rossnagel, G Jacob, S Deffner… - Physical review …, 2012 - APS
We propose an experimental scheme to realize a nanoheat engine with a single ion. An Otto
cycle may be implemented by confining the ion in a linear Paul trap with tapered geometry …

Trade-off between speed and cost in shortcuts to adiabaticity

S Campbell, S Deffner - Physical review letters, 2017 - APS
Achieving effectively adiabatic dynamics is a ubiquitous goal in almost all areas of quantum
physics. Here, we study the speed with which a quantum system can be driven when …

Quantum-trajectory approach to the stochastic thermodynamics of a forced harmonic oscillator

JM Horowitz - Physical Review E—Statistical, Nonlinear, and Soft …, 2012 - APS
I formulate a quantum stochastic thermodynamics for the quantum trajectories of a
continuously monitored forced harmonic oscillator coupled to a thermal reservoir. Consistent …

Efficiency of heat engines coupled to nonequilibrium reservoirs

O Abah, E Lutz - Europhysics Letters, 2014 - iopscience.iop.org
We consider quantum heat engines that operate between nonequilibrium stationary
reservoirs. We evaluate their maximum efficiency from the positivity of the entropy production …

Quantum work and the thermodynamic cost of quantum measurements

S Deffner, JP Paz, WH Zurek - Physical Review E, 2016 - APS
Quantum work is usually determined from two projective measurements of the energy at the
beginning and at the end of a thermodynamic process. However, this paradigm cannot be …

Quantum-classical correspondence principle for work distributions

C Jarzynski, HT Quan, S Rahav - Physical review X, 2015 - APS
For closed quantum systems driven away from equilibrium, work is often defined in terms of
projective measurements of initial and final energies. This definition leads to statistical …
