Quantum Physics Contradicts the Second Law of Thermodynamics
In the current issue of Foundations of Physics, we present a Gedankenexperiment that reveals a highly surprising, fundamental inconsistency between quantum theory and thermodynamics.
This photonic experiment, which can be performed in a practical manner, comprises two black bodies coupled by two chiral waveguides to a set of two-level systems that absorb and emit radiation. Our experiment combines coherent propagation of photons with random absorption and emission. We show that this combination forces an isolated thermodynamic system that is in standard thermodynamic equilibrium to reduce its total entropy. The Gedankenexperiment thereby demonstrates that the foundations of quantum physics, coherence and probabilistic events, contradict the second law of thermodynamics!
For movie buffs – as we have placed the manuscript on arXiv already in 2018, we have beaten Hollywood by two years! [tenet trailer]. For electronic freaks: the idea also works in electronic devices: arXiv:1912.11948.
