Entanglement renormalization of thermofield double states
Cheng-Ju Lin, Zhi Li, Timothy H. Hsieh
Entanglement renormalization is a method for coarse-graining a quantum state in real space, with the multi-scale entanglement renormalization ansatz (MERA) as a notable example. We…
Reaction-diffusion dynamics in a Fibonacci chain: Interplay between classical and quantum behavior
Cheng-Ju Lin, Liujun Zou
We study the reaction-diffusion dynamics of Fibonacci anyons in a one dimensional lattice. Due to their non-Abelian nature, besides the position degree of freedom (DOF), these anyo…
Quantum Many-Body Scar States in Two-Dimensional Rydberg Atom Arrays
Cheng-Ju Lin, Vladimir Calvera, Timothy H. Hsieh
We find exponentially many exact quantum many-body scar states in a two-dimensional PXP model -- an effective model for a two-dimensional Rydberg atom array in the nearest-neighbor…
Unified structure for exact towers of scar states in the AKLT and other models
Daniel K. Mark, Cheng-Ju Lin, Olexei I. Motrunich
Quantum many-body scar states are many-body states with finite energy density in non-integrable models that do not obey the eigenstate thermalization hypothesis. Recent works have…
New exact eigenstates in the Lesanovsky model, proximity to integrability and the PXP model, and approximate scar states
Daniel K. Mark, Cheng-Ju Lin, Olexei I. Motrunich
We study a model of Rydberg atoms in a nearest-neighbor Rydberg blockaded regime, introduced by Lesanovsky in Phys. Rev. Lett. 108, 105301 (2012). This many-body model (which has o…
Slow Thermalization of Exact Quantum Many-Body Scar States Under Perturbations
Cheng-Ju Lin, Anushya Chandran, Olexei I. Motrunich
Quantum many-body scar states are exceptional finite energy density eigenstates in an otherwise thermalizing system that do not satisfy the eigenstate thermalization hypothesis. We…
