Active matter breaks time-reversal symmetry, leading to odd transport phenomena. But formalizing the deep connection between microscopic symmetry breaking and macroscopic oddness requires a different framework. It all begins with the “flux hypothesis...”

@UCBerkeley, @univ_paris_cite
Very proud to announce our latest out today in @PhysRevLett as an Editors' Suggestion!
We apply isoperimetric inequalities to derive a novel bound on efficiency for any thermodynamic cycle and construct new, geometrically optimal cycles.

As the self-appointed hype man, Kranthi's group will be having a rolling thunder of talks throughout Wednesday (special pointer to my talk, Q46, which will have some fun recent ventures with graph neural networks), and then Kranthi himself on Thursday (W14) #apsmarch
This feels like that start of something big: Avishek @pleplostelous and Ben’s @benkuznetsspeck Variational Path Sampling (VPS) paper is out in PRL today. It’s a conceptually new way to study rare events and applicable to systems far from equilibrium. https://t.co/WuTCvurqCJ
BREAKING: UC agrees to recognize SRU-UAW in its entirety! This historic victory was brought about by the tireless efforts of thousands of SRs who organized to win a union & a direct response to our massive Strike Authorization Vote. Now let’s win a strong contract for all SRs!
Pretty cool to read this JCCM commentary on our latest paper, which concludes that active matter research has motivated "a fruitful reexamination of the most basic concepts in statistical physics." That might sound grandiose, but I think it's true!

My article with @jmlepstein and Kranthi Mandadapu is now out in PRL! We write about odd diffusivity -- which drives diffusive fluxes perpendicular to concentration gradients -- and how it emerges in chiral random motion, including in active matter.
Odd diffusivity—corresponding to an antisymmetric component of the diffusivity tensor—emerges as a result of breaking time-reversal and parity symmetries in chiral active matter https://t.co/iqujdq9eJZ
In this paper we show that odd diffusivity is a feature of any random motion which breaks time-reversal and parity symmetries. The Hall effect is a classic example, but this is also relevant for active matter, which can break time-reversal symmetry due to non-conserved forces.
