Constraints on phantom codes from automorphism group bounds
Arthur S. Morris, Daniel Malz
Executing a logical quantum circuit fault-tolerantly incurs a large spacetime overhead. Recent work has proposed and investigated phantom codes, defined by the property that every…
Euler topology in classical spin liquids
Luca Rüegg, Arthur Morris, Han Yan +1
Classical spin liquids have recently been analyzed in view of the single-gap homotopy classification of their dispersive eigenvectors. We show that the recent progress in defining…
Non-Abelian Hopf-Euler insulators
Wojciech J. Jankowski, Arthur S. Morris, Zory Davoyan +3
We discuss a class of three-band non-Abelian topological insulators in three dimensions that carry a single bulk Hopf index protected by spatiotemporal () inversion s…
Optical manifestations and bounds of topological Euler class
Wojciech J. Jankowski, Arthur S. Morris, Adrien Bouhon +2
We analyze quantum-geometric bounds on optical weights in topological phases with pairs of bands hosting nontrivial Euler class, a multigap invariant characterizing non-Abelian ban…
