SUMMARY:Seminar: 'Classical Krylov probes and chaotic semiclassical strings'
DESCRIPTION:Title: ‘Classical Krylov probes and chaotic semiclassical strings’ \nSpeaker: Saskia Demulder (CUNEF) \nVenue&Time: Red Room / 15:00 \nAbstract: Quantum chaos is a central theme in string theory\, but classical chaos is also a generic feature of semiclassical string dynamics. Motivated by the need to explore the broad landscape of non-integrable string dynamics\, I will introduce a classical version of Krylov complexity and related diagnostics using the Koopman-von Neumann formulation of classical mechanics. I will then explain how this framework can be applied to integrability-breaking deformations of otherwise integrable semiclassical string solutions. In particular\, I will show how such deformations induce characteristic redistributions of spectral weight\, leading to observable-dependent delocalisation and spreading in Koopman-Krylov space. This talk is based on [2602.23421] and ongoing work\, both in collaboration with Rathindra N. Das.
