Absolutely, they're still handing out nobels after all. Personally I think the ER=EPR conjecture and the complexity/action duality hypothesis are incredibly interesting. Technically ER=EPR was formulated in 2000s (maybe 90s?) and CA-duality is approaching if not just past 10 years old, but the thing about asking for breakthroughs is that they take a while to percolate. Ex Hawking radiation wasn't formulated until, like, 50-70 years after the "basis" (schwarzshild, Schrodinger) was formed. There's also been a ton of productive research integrsting computer science and physics lately ( on hn…

<ctl>+f entropy didn't return anything, so I went looking for the paper. It looks like it is: "High-Temperature Gibbs States are Unentangled and Efficiently Preparable" [0] but maybe it is "Structure learning of Hamiltonians from real-time evolution" [1] 0. https://arxiv.org/abs/2403.16850 1. https://arxiv.org/abs/2405.00082

For practitioners, a rough description of their argument is on pg 7 (note: separable=unentangled, β =1/kb T) of https://arxiv.org/pdf/2403.16850 This state [rho] is the Gibbs state at infinite temperature, and is in the interior of the convex hull of product states. So, as β tends to zero, ρ will eventually enter the interior of this convex hull, making it separable. This happens at a finite β which depends on system size.
