Pareto-optimal work extraction and the thermodynamic cost of precision in quantum information engines
Jonas Berx, Ted Olander, Henning Kirchberg
We study a finite-time quantum information engine in which a two-level system is measured by a quantum harmonic oscillator acting as a meter and where useful work is extracted cond…
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…
Quantum information engines: Bounds on performance metrics by measurement time
Henning Kirchberg, Abraham Nitzan
Information engines, sometimes referred to as Maxwell Demon engines, utilize information obtained through measurement to control the conversion of energy into useful work. Discussi…
Quantum Information Engines: Assessing Time, Cost and Performance Criteria
Henning Kirchberg, Abraham Nitzan
In this study, we investigate the crucial role of measurement time (), information gain and energy consumption in information engines (IEs) utilizing a von-Neumann measurement…
Energy Conversion and Entropy Production in Biased Random Walk Processes -- from Discrete Modeling to the Continuous Limit
Henning Kirchberg, Abraham Nitzan
We consider discrete and continuous representations of a thermodynamic process in which a random walker (e.g. a molecular motor on a molecular track) uses a periodically pumped ene…
Noise and Thermodynamic Uncertainty Relation in "Underwater" Molecular Junctions
Henning Kirchberg, Abraham Nitzan
We determine the zero-frequency charge current noise in a metal-molecule-metal junction embedded in a thermal environment, e.g., a solvent, dominated by sequential charge transmiss…
Spectroscopic Signatures of the Dynamical Hydrophobic Solvation Shell Formation
Henning Kirchberg, Peter Nalbach, Christian Bressler +1
When a hydrophilic solute in water is suddenly turned into a hydrophobic species, for instance, by photoionization, a layer of hydrated water molecules forms around the solute on a…
Energy Transfer and Thermoelectricity in Molecular Junctions in Non-Equilibrated Solvents
Henning Kirchberg, Abraham Nitzan
We consider a molecular junction immersed in a solvent where the electron transfer is dominated by Marcus-type steps. However, the successive nature of the charge transfer through…
Time-Resolved Probing of the Nonequilibrium Structural Solvation Dynamics by the Time-Dependent Stokes Shift
Henning Kirchberg, Michael Thorwart
The time-dependent fluorescence Stokes shifts monitors the relaxation of the polarization of a polar solvent in the surroundings of a photoexcited solute molecule, but also the str…
Charge Transfer Through Redox Molecular Junctions in Non-Equilibrated Solvents
Henning Kirchberg, Michael Thorwart, Abraham Nitzan
Molecular conduction operating in dielectric solvent environments are often described using kinetic rates based on Marcus theory of electron transfer at a molecule-metal electrode…
Nonequilibrium quantum solvation with a time-dependent Onsager cavity
Henning Kirchberg, Peter Nalbach, Michael Thorwart
We formulate a theory of nonequilibrium quantum solvation in which parameters of the solvent are explicitly depending on time. We assume in a simplest approach a spherical molecula…
