Optimal paths across potentials on scalar field space
Saskia Demulder, Dieter Lust, Carmine Montella +1
Motivated by the Swampland Distance Conjecture, we study distances in field space using the framework of Optimal Transport. The associated optimisation problem naturally leads to a…
Integrability breaking in semiclassical strings in Koopman-Krylov space
Rathindra Nath Das, Saskia Demulder
While very powerful, integrability in semiclassical string solutions is known to be a rare property. Motivated by the need to understand and characterise the large landscape of non…
Krylov exponents and power spectra for maximal quantum chaos: an EFT approach
Saskia Demulder, Maria Knysh, Andrew Rolph
We examine the effective field theory (EFT) of maximal chaos through the lens of Krylov complexity and the Universal Operator Growth Hypothesis. We test the relationship between tw…
Spread complexity for the planar limit of holography
Rathindra N. Das, Saskia Demulder, Johanna Erdmenger +1
Complexity is a fundamental characteristic of states within a quantum system. Its use is however mostly limited to bosonic systems, inhibiting its present applicability to supersym…
