Brickwall One-Loop Determinant: Spectral Statistics & Krylov Complexity
Hyun-Sik Jeong, Arnab Kundu, Juan F. Pedraza
We investigate quantum chaotic features of the brickwall model, which is obtained by introducing a stretched horizon - a Dirichlet wall placed outside the event horizon - within th…
Krylov Complexity in Mixed Phase Space
Kyoung-Bum Huh, Hyun-Sik Jeong, Leopoldo A. Pando Zayas +1
We investigate the Krylov complexity of thermofield double states in systems with mixed phase space, uncovering a direct correlation with the Brody distribution, which interpolates…
Fuzzy Spheres in Stringy Matrix Models: Quantifying Chaos in a Mixed Phase Space
Paolo Amore, Leopoldo A. Pando Zayas, Juan F. Pedraza +2
We consider a truncation of the BMN matrix model to a configuration of two fuzzy spheres, described by two coupled non-linear oscillators dependent on the mass parameter . The c…
Kasner interiors from analytic hairy black holes
Daniel Areán, Hyun-Sik Jeong, Juan F. Pedraza +1
We conduct an exhaustive study of the interior geometry of a family of asymptotically AdS hairy black holes in an analytically controllable setup. The black holes are exact…
Krylov complexity as an order parameter for quantum chaotic-integrable transitions
Matteo Baggioli, Kyoung-Bum Huh, Hyun-Sik Jeong +2
Krylov complexity has recently emerged as a new paradigm to characterize quantum chaos in many-body systems. However, which features of Krylov complexity are prerogative of quantum…
Krylov complexity of density matrix operators
Pawel Caputa, Hyun-Sik Jeong, Sinong Liu +2
Quantifying complexity in quantum systems has witnessed a surge of interest in recent years, with Krylov-based measures such as Krylov complexity () and Spread complexity ($C_…
