Happy to share our new work on a seemingly simple but in fact rather radical question: can quantum entanglement be associated with a region extending in time rather than space? In 2d CFT and holography, we give a concrete answer.

@PhysicistAlex Exciting. Big congrats!

The broader lesson: complex bulk saddles are not optional geometric decorations. They are selected by boundary QFT once its observables are continued carefully in time.

The sharpest test is AdS₃-Vaidya. Complex geodesics crossing the collapsing shell reproduce the known CFT correlator—analytically for a thin shell and numerically for thick shells. Earlier piecewise-curve constructions do not reproduce the CFT-defined TEE. 11/12

At weak coupling

[Michal P. Heller @HellerInTheory]

Today on the arXiv: https://t.co/ZhFprXuToy by @ugent and @cuhksz researchers. In this theoretical physics work we re-examined how high energy physics systems approach equilibrium and revealed a unifying mathematical structure despite variety of systems we considered. Why bother?

This plot from the paper shows both weak (vertical zigzag line) and strong (black x's) coupling equilibration mechanisms together as incorporated by our hybrid model.
