Together with @pieterclaeys.bsky.social and Saskia Demulder we are putting together a special issue of J. Phys. A on "Krylov Complexity Across Scales: From Quantum Many-Body Systems to Black Holes". Let me know if you're interested in contributing! Details in this post!
I am grateful to @haskoliislands.bsky.social for the hospitality. I spent last week in Rekyjavik, teaching Statistical Mechanics in person for some days, giving a talk and interacting with fantastic people! I also got the chance to explore a bit this spectacular country.
New preprint out!

We study the spread complexity growth of quantum states along eigenspaces induced by conserved charge sectors. We observe how the total spread non-trivially emerges from the spread of the fixed-charge components!

Our paper has been published on Physical Review A!
In this work, we propose new notions of preorder in the space of bosonic quantum states. Our analysis includes also states with Wigner negativity.
