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…
Renormalisation Group Flows of Deformed SYK Models
Dionysios Anninos, Damián A. Galante, Sameer U. Sheorey
We explore computationally tractable deformations of the SYK model. The deformed theories are described by the sum of two SYK Hamiltonians with differing numbers, and $\tilde{q…
Complex geodesics in de Sitter space
Shira Chapman, Damián A. Galante, Eleanor Harris +2
The two-point function of a free massive scalar field on a fixed background can be evaluated in the large mass limit by using a semiclassical geodesic approximation. In de Sitter s…
