Probing weak chaos in super Yang-Mills and long-range spin chains
Pawel Caputa, Brian Creed, Rathindra Nath Das +2
We study signatures of quantum chaos in finite-loop truncations of the planar dilatation operator in the sector of super Yang-Mills and its -d…
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…
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…
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…
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…
Krylov complexity and chaos in deformed SYK models
Shira Chapman, Saskia Demulder, Damián A. Galante +2
Krylov complexity has recently been proposed as a quantum probe of chaos. The Krylov exponent characterising the exponential growth of Krylov complexity is conjectured to upper-bou…
