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…
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…
Chaos and integrability in triangular billiards
Vijay Balasubramanian, Rathindra Nath Das, Johanna Erdmenger +1
We characterize quantum dynamics in triangular billiards in terms of five properties: (1) the level spacing ratio (LSR), (2) spectral complexity (SC), (3) Lanczos coefficient varia…
Spread complexity and localization in -symmetric systems
Aranya Bhattacharya, Rathindra Nath Das, Bidyut Dey +1
We present a framework for investigating wave function spreading in -symmetric quantum systems using spread complexity and spread entropy. We consider a tight-binding…
