Post Quantum thermodynamics attempts to bend the rules - Nature

In a 1 Nov 2017 article in Nature, Zeeya Merali reports on how
experiments in quantum physics at the University of Oxford are
bending the laws of thermodynamics.

At a lab at the University of Oxford, UK, quantum physicists are trying to do so with a small lump of synthetic diamond. At first, the diamond is barely visible, nestled inside a chaotic mess of optical fibres and mirrors. But when they switch on a green laser, defects in the diamond are illuminated, and the crystal begins to glow red.

In that light, the team has found preliminary evidence of an effect that was theorized only a few years ago: a quantum boost that would push the diamond's power output above the level prescribed by classical thermodynamics. If the results hold up, they will be a tangible boon for the study of quantum thermodynamics, a relatively new field that aims to uncover the rules that govern heat and energy flow at the atomic scale.

There is reason to suspect that the laws of thermodynamics, which are based on how large numbers of particles behave, are different in the quantum realm. Over the past five years or so, a quantum-thermodynamics community has grown around that idea. What was once the domain of a handful of theoreticians now includes a few hundred theoretical and experimental physicists around the globe. “The field is moving so fast I can barely keep up,” says Ronnie Kosloff, an early pioneer of the field at the Hebrew University of Jerusalem in Israel.

thanks for posting gary.

so the unassailable laws of thermodynamics are also turning out to be based on weird stuff at the microscopic level - fascinating. This sort of physics is way beyond my pay grade, but does this add one more indication that the whole universe is sitting on a bedrock of information content?

Modern society seems to me to mirror this at a macro level - information (and its manipulation) is fast becoming the basis for human existence.

cheers Ray

Does this mean in future we'll be able to tap into other energy sources? Freebie?
