Rainbow scars: From area to volume law

CM Langlett, ZC Yang, J Wildeboer, AV Gorshkov… - Physical Review B, 2022 - APS
Quantum many-body scars (QMBS) constitute a new quantum dynamical regime in which
rare “scarred” eigenstates mediate weak ergodicity breaking. One open question is to …

Entanglement hamiltonian and entanglement contour in inhomogeneous 1D critical systems

E Tonni, J Rodriguez-Laguna… - Journal of Statistical …, 2018 - iopscience.iop.org

Exact thermal eigenstates of nonintegrable spin chains at infinite temperature

Y Chiba, Y Yoneta - Physical Review Letters, 2024 - APS
The eigenstate thermalization hypothesis (ETH) plays a major role in explaining
thermalization of isolated quantum many-body systems. However, there has been no proof …

Emergence of curved light-cones in a class of inhomogeneous Luttinger liquids

J Dubail, JM Stéphan, P Calabrese - SciPost Physics, 2017 - scipost.org
The light-cone spreading of entanglement and correlation is a fundamental and ubiquitous
feature of homogeneous extended quantum systems. Here we point out that a class of …

Quantum many-body scars from Einstein-Podolsky-Rosen states in bilayer systems

J Wildeboer, CM Langlett, ZC Yang, AV Gorshkov… - Physical Review B, 2022 - APS
Quantum many-body scar states are special eigenstates of nonintegrable models with
distinctive entanglement features that give rise to infinitely long-lived coherent dynamics …

On the continuum limit of the entanglement Hamiltonian

V Eisler, E Tonni, I Peschel - Journal of Statistical Mechanics …, 2019 - iopscience.iop.org
We consider the entanglement Hamiltonian for an interval in a chain of free fermions in its
ground state and show that the lattice expression goes over into the conformal one if one …

Deformed Fredkin spin chain with extensive entanglement

O Salberger, T Udagawa, Z Zhang… - Journal of Statistical …, 2017 - iopscience.iop.org
We introduce a new spin chain which is a deformation of the Fredkin spin chain and has a
phase transition between bounded and extensive entanglement entropy scaling. In this …
