Title: 

The Quantum Kraken

Abstract:

In this talk I will explore the persistence of embedded eigenvalues of  Schrödinger operators under perturbations on tentacular domains. Embedded eigenvalues present unique challenges, as they lie within the continuous spectrum, making their stability under perturbations a nontrivial problem. The aim of this talk is to first present a published persistence result on cylindrical domains to gain understanding of the problem, after which I will present a new, fun and unfinished (possibly nonsensical)) idea to extend this result to more exotic tentacular domains, consistent with earlier methods and results.

It will be very relaxed and handwavy. But there will also be fika!
