Lieb-Robinson bounds with exponential-in-volume tails
Ben T. McDonough, Chao Yin, Andrew Lucas +1
Lieb-Robinson bounds demonstrate the emergence of locality in many-body quantum systems. Intuitively, Lieb-Robinson bounds state that with local or exponentially decaying interacti…
Non-invertible bosonic chiral symmetry on the lattice
Lukasz Fidkowski, Cenke Xu, Carolyn Zhang
In this work we realize the 3 + 1 dimensional non-invertible chiral symmetry generator as an operator in a many body lattice Hilbert space. A crucial ingredient in…
Anomaly-free symmetries with obstructions to gauging and onsiteability
Wilbur Shirley, Carolyn Zhang, Wenjie Ji +1
We present counterexamples to the lore that symmetries that cannot be gauged or made on-site are necessarily anomalous. Specifically, we construct unitary, internal symmetries of t…
SymTFT Approach for Mixed States with Non-Invertible Symmetries
Sakura Schafer-Nameki, Apoorv Tiwari, Alison Warman +1
We develop a general framework for studying phases of mixed states with strong and weak symmetries, including non-invertible or categorical symmetries. The central idea is to consi…
Enforced Gaplessness from States with Exponentially Decaying Correlations
Rahul Sahay, Curt von Keyserlingk, Ruben Verresen +1
It is well known that an exponentially localized Hamiltonian must be gapless if its ground state has algebraic correlations. We show that even certain exponentially decaying correl…
Thermalization rates and quantum Ruelle-Pollicott resonances: insights from operator hydrodynamics
Carolyn Zhang, Laimei Nie, Curt von Keyserlingk
In thermalizing many-body quantum systems without conservation laws such as ergodic Floquet and random unitary circuits, local expectation values are predicted to decay to their eq…
