On March 17-19, there will be a hybrid #HUBerlin /online workshop on theoretical #physics with a special emphasis on fostering collaboration with Ukrainian researchers. Topics are #quantumFieldTheory, #integrability, and #mathematics in theoretical physics. There are several rather high-profile speakers, it could be interesting to watch online even if you can't make it in person. Registration ends today.

`Kakutani's theorem is a fundamental result on the equivalence or mutual singularity of countable product measures. It gives an "if and only if" characterisation of when two such measures are equivalent, and hence it is extremely useful when trying to establish change-of-measure formulae for measures on function spaces.`

Identifying Quantum Many-Body Integrability and Chaos Using Eigenstate Trace Distances
While the concept of quantum many-body integrability is of fundamental relevance for the understanding of quantum matter, its precise definition has remained open so far. Here, we introduce an alternative indicator, which signals the expected behavior also for models such as the celebrated kicked top, where other established indicators face limitations.

@j_bertolotti Interesting! Limiting scattering channels is something I associate with integrable systems (Bethe Ansatz). To some extent, factorizable interactions can be regarded as integrable, hence ... Would you happen to have a list of those reflectionless potentials? #BetheAnsatz #InfeldHull #integrability

Faribault and collaborators succeed in deriving Richardson-Gaudin 2RDMs in the Eigenvalue-based formalism, *without* the need of computing rapidities .... removing an important bottleneck in Richardson-Gaudin Geminal theory
