Quantum Many-Body Scars from Einstein-Podolsky-Rosen States in Bilayer Systems
Julia Wildeboer, Christopher M. Langlett, Zhi-Cheng Yang +3
Quantum many-body scar states are special eigenstates of nonintegrable models with distinctive entanglement features that give rise to infinitely long-lived coherent dynamics under…
Hilbert Space Fragmentation and Exact Scars of Generalized Fredkin Spin Chains
Christopher M. Langlett, Shenglong Xu
In this work, based on the Fredkin spin chain, we introduce a family of spin- many-body Hamiltonians with a three-site interaction featuring a fragmented Hilbert space with co…
A Sparse Model of Quantum Holography
Shenglong Xu, Leonard Susskind, Yuan Su +1
We study a sparse version of the Sachdev-Ye-Kitaev (SYK) model defined on random hypergraphs constructed either by a random pruning procedure or by randomly sampling regular hyperg…
The Speed of Quantum Information Spreading in Chaotic Systems
Josiah Couch, Stefan Eccles, Phuc Nguyen +2
We present a general theory of quantum information propagation in chaotic quantum many-body systems. The generic expectation in such systems is that quantum information does not pr…
Quantum Many-Body Scars and Space-Time Crystalline Order from Magnon Condensation
Thomas Iadecola, Michael Schecter, Shenglong Xu
We study the eigenstate properties of a nonintegrable spin chain that was recently realized experimentally in a Rydberg-atom quantum simulator. In the experiment, long-lived cohere…
Butterfly effect in interacting Aubry-Andre model: thermalization, slow scrambling, and many-body localization
Shenglong Xu, Xiao Li, Yi-Ting Hsu +2
The many-body localization transition in quasiperiodic systems has been extensively studied in recent ultracold atom experiments. At intermediate quasiperiodic potential strength,…
