Quantum Fuel with Multilevel Atomic Coherence for Ultrahigh Specific Work in a Photonic Carnot Engine

, 2015
We investigate scaling of work and efficiency of a photonic Carnot engine with the number of quantum coherent resources. Specifically, we consider a generalization of the "phaseonium fuel" for the photonic Carnot engine, which was first introduced as a ...

Self‐Maintained Thermal Charging Cells for the Efficient Harvesting of Waste Heat at Elevated Temperatures

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
Thermal charging cells (TCS) face two main challenges that limit their practical applications: 1) Still lacking the systems suitable for operation under higher temperature environments, and 2) there are limitations in the self‐sustaining performance of continuous discharge under temperature differences, which holds critical significance for the real ...
