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…
Charging Quantum Batteries with Chiral Squeezing
Borhan Ahmadi, André H. A. Malavazi, Janine Splettstoesser +2
We propose a quantum-battery charger based on a driven bosonic Kitaev chain (BKC), where chiral squeezing converts passive input fluctuations into ordered, non-passive battery stat…
Nonlinear quantum optomechanics in a Fano-mirror microcavity system
Lei Du, Juliette Monsel, Witlef Wieczorek +1
We study a Fano-mirror optomechanical system in the quantum nonlinear regime. In this system, two strongly lossy optical modes hybridize through both coherent and dissipative coupl…
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…
Improving photovoltaics by adding extra terminals to extract hot carriers
Bruno Bertin-Johannet, Thibaut Thuégaz, Janine Splettstoesser +1
Photovoltaic cells usually have two terminals, one collecting electrons and the other collecting holes. Can more terminals improve such solar cells? Energy-filtering terminals coul…
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…
