Geometric Optimisation of Quantum Thermodynamic Processes
A pedagogical introduction to the notion of thermodynamic length is introduced, and a geometric lower bound on entropy production in finite-time is presented, which represents a quantum generalisation of the original classical bound.
Entropy production and time asymmetry in the presence of strong interactions.
It is shown that the average entropy production quantifies the extent to which the system and bath state is driven away from the conditional equilibrium distribution and that the stochastic entropy production satisfies a generalized Crooks relation and can be used to quantify time asymmetry of correlated nonequilibrium processes.

This work shows that quantum fluctuations prohibit finding slow protocols that minimize both dissipation and fluctuations simultaneously, in contrast to classical slow processes, and develops a quantum geometric framework to find processes with an optimal trade-off between the two quantities.
Quantum Fluctuations Hinder Finite-Time Information Erasure near the Landauer Limit.
It is demonstrated that quantum coherence generated in the energy eigenbasis of a system undergoing a finite-time information erasure protocol yields rare events with extreme dissipation that yield distinct, experimentally distinguishable signatures.
Energy-temperature uncertainty relation in quantum thermodynamics
It is shown that the non-commutativity between the system’s state and its effective energy operator gives rise to quantum fluctuations that increase the temperature uncertainty, which sheds light on the interplay between classical and non-classical fluctuations in quantum thermodynamics.
Time-reversal symmetric work distributions for closed quantum dynamics in the histories framework
A central topic in the emerging field of quantum thermodynamics is the definition of thermodynamic work in the quantum regime. One widely used solution is to define work for a closed system…
Thermodynamic Uncertainty Relation in Slowly Driven Quantum Heat Engines.
In the present Letter, a different class of heat engines are analyzed, namely, those which are operating in the periodic slow-driving regime, and it is shown that an alternative TUR is satisfied, which is less restrictive than that of steady-state engines.
Quantum work statistics close to equilibrium
We study the statistics of work, dissipation, and entropy production of a quantum quasi-isothermal process, where the system remains close to the thermal equilibrium along the transformation. We…
Measurement-dependent corrections to work distributions arising from quantum coherences
P.S. has received funding from the European Union FP7/2007-2013 under REA Grant Agreement No. 630925–COHEAT and from MIUR-FIRB2013–Project Coca (Grant No. RBFR1379UX). H.J.D.M. is supported by EPSRC…
Geometry of Work Fluctuations versus Efficiency in Microscopic Thermal Machines.
This work characterize the optimal protocols for continuous-variable Gaussian machines, which form a crucial class in the study of thermodynamics for microscopic systems, and utilizes techniques from thermodynamic geometry.
