One equation to rule all of them?


In lieu of composing a weblog publish this month, I’m publishing an article in Quanta Journal. The article gives an introduction to fluctuation relations, souped-up variations on the second legislation of thermodynamics, which helps us perceive why time flows in just one route. The earliest fluctuation relations described classical programs, akin to single strands of DNA. Many quantum variations have been proved since. Their proliferation contrasts with the stereotype of physicists as obsessive about unification—with slimming down a cadre of equations into one über-equation. Will one quantum fluctuation relation emerge to rule all of them? Possibly, and perhaps not. Possibly the multiplicity of quantum fluctuation relations displays the richness of quantum thermodynamics.

You’ll be able to learn extra in Quanta Journal right here and but extra in chapter 9 of my e book. For current advances in fluctuation relations, versus the broad introduction there, try earlier Quantum Frontiers posts right here, right here, right here, right here, and right here.

About Nicole Yunger Halpern

I’m a theoretical physicist on the Joint Middle for Quantum Info and Pc Science in Maryland. My analysis group re-envisions Nineteenth-century thermodynamics for the twenty first century, utilizing the mathematical toolkit of quantum info principle. We then apply quantum thermodynamics as a lens by way of which to view the remainder of science. I name this analysis “quantum steampunk,” after the steampunk style of artwork and literature that juxtaposes Victorian settings (à la thermodynamics) with futuristic applied sciences (à la quantum info). For extra info, try my upcoming e book Quantum Steampunk: The Physics of Yesterday’s Tomorrow. I earned my PhD at Caltech beneath John Preskill’s auspices; one in all my life targets is to be the topic of one in all his well-known (if not Pullitzer-worthy) poems.
