When Maxwell's Demon Conducts the Quantum Choir
The old question of Maxwell’s demon, can an intelligent being circumvent the second law of thermodynamics and pump heat from cold to hot, gains new resonance in the quantum world.
Quantum Engine vs. Carnot's Barrier: Power and Efficiency Without Compromise
In classical thermodynamics, heat engines are like a virtuoso musician on stage: the closer to perfection in performance (Carnot efficiency), the slower the tempo (power).
