Stochastic strong zero modes and their dynamical manifestations
Katja Klobas, Paul Fendley, Juan P. Garrahan
Strong zero modes (SZMs) are conserved operators localised at the edges of certain quantum spin chains, which give rise to long coherence times of edge spins. Here we define and an…
Microscopic characterization of Ising conformal field theory in Rydberg chains
Kevin Slagle, David Aasen, Hannes Pichler +5
Rydberg chains provide an appealing platform for probing conformal field theories (CFTs) that capture universal behavior in a myriad of physical settings. Focusing on a Rydberg cha…
Topological Defects on the Lattice: Dualities and Degeneracies
David Aasen, Paul Fendley, Roger S. K. Mong
We construct topological defects in two-dimensional classical lattice models and quantum chains. The defects satisfy local commutation relations guaranteeing that the partition fun…
Integrability and braided tensor categories
Paul Fendley
Many integrable statistical mechanical models possess a fractional-spin conserved current. Such currents have been constructed by utilising quantum-group algebras and ideas from "d…
Large Classes of Quantum Scarred Hamiltonians from Matrix Product States
Sanjay Moudgalya, Edward O'Brien, B. Andrei Bernevig +2
Motivated by the existence of exact many-body quantum scars in the AKLT chain, we explore the connection between Matrix Product State (MPS) wavefunctions and many-body quantum scar…
Self-dual -invariant quantum chains
Edward O'Brien, Paul Fendley
We investigate the self-dual three-state quantum chain with nearest-neighbor interactions and , time-reversal, and parity symmetries. We find a rich phase diagram including ga…
