Optimal control of dissipation and work fluctuations for rapidly driven systems
Alberto Rolandi, Martí Perarnau-Llobet, Harry J. D. Miller
To achieve efficient and reliable control of microscopic systems one should look for driving protocols that mitigate both the average dissipation and stochastic fluctuations in wor…
Critical quantum metrology assisted by real-time feedback control
Raffaele Salvia, Mohammad Mehboudi, Martí Perarnau-Llobet
We investigate critical quantum metrology,that is the estimation of parameters in many-body systems close to a quantum critical point, through the lens of Bayesian inference theory…
Finite-time Landauer principle beyond weak coupling
Alberto Rolandi, Martí Perarnau-Llobet
Landauer's principle gives a fundamental limit to the thermodynamic cost of erasing information. Its saturation requires a reversible isothermal process, and hence infinite time. W…
Minimally dissipative information erasure in a quantum dot via thermodynamic length
Matteo Scandi, David Barker, Sebastian Lehmann +3
In this work we explore the use of thermodynamic length to improve the performance of experimental protocols. In particular, we implement Landauer erasure on a driven electron leve…
Characterizing the performance of heat rectifiers
Shishir Khandelwal, Martí Perarnau-Llobet, Stella Seah +2
A physical system connected to two thermal reservoirs at different temperatures is said to act as a heat rectifier when it is able to bias the heat current in a given direction, si…
Probing coherent quantum thermodynamics using a trapped ion
O. Onishchenko, G. Guarnieri, P. Rosillo-Rodes +6
Quantum thermodynamics is aimed at grasping thermodynamic laws as they apply to thermal machines operating in the deep quantum regime, a regime in which coherences and entanglement…
Pareto-optimal cycles for power, efficiency and fluctuations of quantum heat engines using reinforcement learning
Paolo Andrea Erdman, Alberto Rolandi, Paolo Abiuso +2
The full optimization of a quantum heat engine requires operating at high power, high efficiency, and high stability (i.e. low power fluctuations). However, these three objectives…
Operational definition of the temperature of a quantum state
Patryk Lipka-Bartosik, Martí Perarnau-Llobet, Nicolas Brunner
Temperature is usually defined for physical systems at thermal equilibrium. Nevertheless one may wonder if it would be possible to attribute a meaningful notion of temperature to a…
Quantum advantage in charging cavity and spin batteries by repeated interactions
Raffaele Salvia, Martí Perarnau-Llobet, Géraldine Haack +2
Recently, an unconditional advantage has been demonstrated for the process of charging of a quantum battery in a collisional model. Motivated by the question of whether such an adv…
Thermodynamics and optimal protocols of multidimensional quadratic Brownian systems
Paolo Abiuso, Viktor Holubec, Janet Anders +3
We characterize finite-time thermodynamic processes of multidimensional quadratic overdamped systems. Analytic expressions are provided for heat, work, and dissipation for any evol…
Optimal finite-time heat engines under constrained control
Zhuolin Ye, Federico Cerisola, Paolo Abiuso +3
We optimize finite-time stochastic heat engines with a periodically scaled Hamiltonian under experimentally motivated constraints on the bath temperature and the scaling parame…
