Assisted harvesting and catalysis of coherence from scalar fields
Nikolaos K. Kollas, Dimitris Moustos
Recently it has been demonstrated that it is possible to harvest quantum resources other than entanglement from a coherent scalar field. Employing time-dependent perturbation theor…
Field assisted extraction and swelling of quantum coherence for moving Unruh-DeWitt detectors
Nikolaos K. Kollas, Dimitris Moustos, Kostas Blekos
We study the effects of motion for an Unruh-DeWitt detector, modeled as a two-level system, on the amount of coherence extracted, when it interacts with a massless scalar coherent…
Faithful extraction of quantum coherence
Nikolaos K. Kollas, Kostas Blekos
Coherence, a strictly quantum phenomenon, has found many applications, from quantum information theory and thermodynamics to quantum foundations and biology. When physical constrai…
Optimization free measures of quantum resources
Nikolaos K. Kollas
A closed expression is derived for the amount of resource present in a quantum state as quantified by a distance measure based on the \emph{Tsallis relative entropy} introduced rec…
Thermodynamics of bipartite entanglement
Nikolaos K. Kollas
A review is given on the thermodynamical structure of bipartite entanglement. By comparing it to the axiomatic formulation of thermodynamics presented by Giles it is shown that for…
