@informaq.bsky.socialNovel quantum heat engine design uses Maxwell's demon feedback to achieve near-perfect efficiency and high power output simultaneously, overcoming fundamental quasi-static performance limitations through quantum coherence preservation.
@informaq.bsky.socialSplettstösser reveals that thermodynamic and kinetic uncertainty relations constrain fluctuations in quantum heat engines, addressing limitations of applying weakly-coupled theories to strongly-coupled small-scale thermoelectric devices.
