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!
arxiv.org/abs/2509.12992
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!

Symmetry-Resolved Spread Complexity
In this work, we investigate the impact of conserved charges on the dynamics of spread complexity of quantum states. Building on the notion of symmetry-resolved Krylov complexity [1], we extend the fr...

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.

Continuous majorization in quantum phase space for Wigner-positive states and proposals for Wigner-negative states
In quantum resource theory, one is often interested in identifying which states serve as the best resources for particular quantum tasks. If a relative comparison between quantum states can be made, t...
