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…

Wormhole-induced effective coupling in SYK chains

Pablo Basteiro, Giuseppe Di Giulio, Johanna Erdmenger +2

Inhomogeneous quantum chains have recently been considered in the context of developing novel discrete realizations of holographic dualities. To advance this programme, we explore…

Simulating Holographic Conformal Field Theories on Hyperbolic Lattices

Santanu Dey, Anffany Chen, Pablo Basteiro +10

We demonstrate how table-top settings combining hyperbolic lattices with nonlinear dynamics universally encode aspects of the bulk-boundary-correspondence between gravity in anti-d…

Entanglement in interacting Majorana chains and transitions of von Neumann algebras

Pablo Basteiro, Giuseppe Di Giulio, Johanna Erdmenger +1

We consider Majorana lattices with two-site interactions consisting of a general function of the fermion bilinear. The models are exactly solvable in the limit of a large number of…

Geometric Quantum Discord Signals Non-Factorization

Souvik Banerjee, Pablo Basteiro, Rathindra Nath Das +1

We propose the information-theoretic quantity of geometric quantum discord (GQD) as an indicator of the factorization properties of a given quantum system. In particular, we show h…

Aperiodic spin chains at the boundary of hyperbolic tilings

Pablo Basteiro, Rathindra Nath Das, Giuseppe Di Giulio +1

In view of making progress towards establishing a holographic duality for theories defined on a discrete tiling of the hyperbolic plane, we consider a recently proposed boundary sp…

Towards Explicit Discrete Holography: Aperiodic Spin Chains from Hyperbolic Tilings

Pablo Basteiro, Giuseppe Di Giulio, Johanna Erdmenger +3

We propose a new example of discrete holography that provides a new step towards establishing the AdS/CFT duality for discrete spaces. A class of boundary Hamiltonians is obtained…

Breitenlohner-Freedman bound on hyperbolic tilings

Pablo Basteiro, Felix Dusel, Johanna Erdmenger +4

We establish how the Breitenlohner-Freedman (BF) bound is realized on tilings of two-dimensional Euclidean Anti-de Sitter space. For the continuum, the BF bound states that on Anti…

Fractional Klein-Gordon Equation on AdS

Pablo Basteiro, Janine Elfert, Johanna Erdmenger +1

We propose a covariant definition of the fractional Klein-Gordon equation with long-range interactions independent of the metric of the underlying manifold. As an example we consid…

Quantum Complexity as Hydrodynamics

Pablo Basteiro, Johanna Erdmenger, Pascal Fries +3

As a new step towards defining complexity for quantum field theories, we map Nielsen operator complexity for gates to two-dimensional hydrodynamics. We develop a tractable…
