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…
Experimental observation of hyperbolic spacetime dynamics
Jonas Himmel, Coraline Bacq, Krishna Chand Maurya +11
Understanding quantum dynamics in curved spacetime is a central challenge at the intersection of quantum mechanics and gravity. Anti-de-Sitter (AdS) spacetime plays a pivotal role…
Probing the Chaos to Integrability Transition in Double-Scaled SYK
Sergio E. Aguilar-Gutierrez, Rathindra Nath Das, Johanna Erdmenger +1
We investigate how a thermodynamical first-order phase transition affects the dynamical chaotic behaviour of a given model. To this effect, we analyze the model of Berkooz, Brukner…
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…
Complexity and the Hilbert space dimension of 3D gravity
Vijay Balasubramanian, Rathindra Nath Das, Johanna Erdmenger +2
A central problem in formulating a theory of quantum gravity is to determine the size and structure of the Hilbert space of black holes. Here we use a quantum dynamical Krylov comp…
Timelike Entanglement Signatures of Ergodicity and Spectral Chaos
Rathindra Nath Das, Arnab Kundu, Nemai Chandra Sarkar
We investigate timelike entanglement measures derived from the spacetime density kernel in the Rosenzweig-Porter model and show that they sharply diagnose both eigenvector ergodici…
