An autonomous feedback protocol: responding to temperature and potential changes in energy converters
Elsa Danielsson, Krishna Lyn Delima, Bruno Bertin-Johannet +1
Nanoscale thermoelectric devices convert tiny amounts of heat into power. But what happens if the external conditions and resulting temperature differences are not a priori known?…
Activating thermally charged quantum batteries in finite time: Thermodynamic trade-offs between correlations, work, and information
Bhaskar Barman, Janine Splettstoesser, Henning Kirchberg
Thermally charged quantum batteries provide a stable and easy-to-have energy resource, but remain passive and therefore do not allow useful energy extraction on demand via unitary…
Optimizing energy conversion with nonthermal resources in steady-state quantum devices
Elsa Danielsson, Henning Kirchberg, Janine Splettstoesser
We provide a framework for optimizing energy conversion processes in coherent quantum conductors fed by nonthermal resources. Such nonthermal resources, which cannot be characteriz…
Optimising finite-time quantum information engines using Pareto bounds
Rasmus Hagman, Jonas Berx, Janine Splettstoesser +1
Information engines harness measurement and feedback to convert energy into useful work. In this study, we investigate the fundamental trade-offs between ergotropic output power, t…
