Coherence-assisted single-shot cooling by quantum absorption refrigerators
Mark T. Mitchison,Mark T. Mitchison,Mischa P. Woods,Mischa P. Woods,Javier Prior,Marcus Huber +5 more
TL;DR: In this article, the authors explore the finite-time dynamics of absorption refrigerators composed of three qubits and show that coherent oscillations inherent to quantum dynamics can be harnessed to reach temperatures that are colder than the steady state in orders of magnitude less time, thereby providing a fast source of low-entropy qubits.

Work, entropy production, and thermodynamics of information under protocol constraints
TL;DR: This work shows that for any operator $\phi$ over distributions that obeys the Pythagorean theorem from information geometry and commutes with the set of available dynamical generators, the contraction of KL divergence provides a non-negative lower bound on EP.

Work, Entropy Production, and Thermodynamics of Information under Protocol Constraints
TL;DR: In this paper, a thermodynamic framework provides new bounds on how much work can be extracted from a system under nonidealized, real-world conditions, based on the assumption that the system is stable.

Catalytic transformations with finite-size environments: applications to cooling and thermometry
Ivan Henao,Raam Uzdin +1 more
TL;DR: In this paper, the authors study catalytic transformations that cannot be achieved when a system exclusively interacts with a finite environment and present constructive conditions for these transformations, including the corresponding global unitary operation and the explicit states of all the systems involved.

Fundamental limitations for quantum and nanoscale thermodynamics
TL;DR: It is found that there are fundamental limitations on work extraction from non-equilibrium states, owing to finite size effects and quantum coherences, which implies that thermodynamical transitions are generically irreversible at this scale.

The second laws of quantum thermodynamics
Fernando G. S. L. Brandão,Michał Horodecki,Nelly Huei Ying Ng,Jonathan Oppenheim,Jonathan Oppenheim,Stephanie Wehner +5 more
TL;DR: Here, it is found that for processes which are approximately cyclic, the second law for microscopic systems takes on a different form compared to the macroscopic scale, imposing not just one constraint on state transformations, but an entire family of constraints.

Quantum Thermodynamics
Sai Vinjanampathy,Janet Anders +1 more
TL;DR: Quantum thermodynamics is an emerging research field aiming to extend standard thermodynamics and non-equilibrium statistical physics to ensembles of sizes well below the thermodynamic limit.

Description of quantum coherence in thermodynamic processes requires constraints beyond free energy.
TL;DR: It is shown that free energy relations cannot properly describe quantum coherence in thermodynamic processes, and it is found that coherence transformations are always irreversible.

Fundamental aspects of steady-state conversion of heat to work at the nanoscale
TL;DR: In this paper, the authors introduce some of the theories used to describe these steady-state flows in a variety of mesoscopic or nanoscale systems, including linear response theory with or without magnetic fields, Landauer scattering theory in the linear response regime and far from equilibrium.
