Theory of nonequilibrium free energy transduction by molecular machines

AI Brown, DA Sivak - Chemical reviews, 2019 - ACS Publications
Biomolecular machines are protein complexes that convert between different forms of free
energy. They are utilized in nature to accomplish many cellular tasks. As isothermal …

Optimal cycles for low-dissipation heat engines

P Abiuso, M Perarnau-Llobet - Physical review letters, 2020 - APS
We consider the optimization of a finite-time Carnot engine characterized by small
dissipations. We bound the power with a simple inequality and show that the optimal …

Collective advantages in finite-time thermodynamics

A Rolandi, P Abiuso, M Perarnau-Llobet - Physical Review Letters, 2023 - APS
A central task in finite-time thermodynamics is to minimize the excess or dissipated work W
diss when manipulating the state of a system immersed in a thermal bath. We consider this …

Geometric optimisation of quantum thermodynamic processes

P Abiuso, HJD Miller, M Perarnau-Llobet, M Scandi - Entropy, 2020 - mdpi.com
Differential geometry offers a powerful framework for optimising and characterising finite-
time thermodynamic processes, both classical and quantum. Here, we start by a …

Violating the thermodynamic uncertainty relation in the three-level maser

AAS Kalaee, A Wacker, PP Potts - Physical Review E, 2021 - APS
Nanoscale heat engines are subject to large fluctuations which affect their precision. The
thermodynamic uncertainty relation (TUR) provides a trade-off between output power …

Thermodynamic length in open quantum systems

M Scandi, M Perarnau-Llobet - Quantum, 2019 - quantum-journal.org
The dissipation generated during a quasistatic thermodynamic process can be
characterised by introducing a metric on the space of Gibbs states, in such a way that …

Thermodynamic uncertainty relation in slowly driven quantum heat engines

HJD Miller, MH Mohammady, M Perarnau-Llobet… - Physical review …, 2021 - APS
Thermodynamic uncertainty relations express a trade-off between precision, defined as the
noise-to-signal ratio of a generic current, and the amount of associated entropy production …

Work fluctuations in slow processes: quantum signatures and optimal control

HJD Miller, M Scandi, J Anders, M Perarnau-Llobet - Physical review letters, 2019 - APS
An important result in classical stochastic thermodynamics is the work fluctuation-dissipation
relation (FDR), which states that the dissipated work done along a slow process is …

Thermodynamic control—An old paradigm with new applications

S Deffner, MVS Bonança - Europhysics Letters, 2020 - iopscience.iop.org
Tremendous research efforts have been invested in exploring and designing so-called
shortcuts to adiabaticity. These are finite-time processes that produce the same final states …

Speed-ups to isothermality: Enhanced quantum thermal machines through control of the system-bath coupling

N Pancotti, M Scandi, MT Mitchison, M Perarnau-Llobet - Physical Review X, 2020 - APS
Isothermal transformations are minimally dissipative but slow processes, as the system
needs to remain close to thermal equilibrium along the protocol. Here, we show that …
