Bulk-boundary correspondence and singularity-filling in long-range free-fermion chains
Nick G. Jones, Ryan Thorngren, Ruben Verresen
The bulk-boundary correspondence relates topologically-protected edge modes to bulk topological invariants, and is well-understood for short-range free-fermion chains. Although cas…
Higgs Condensates are Symmetry-Protected Topological Phases: I. Discrete Symmetries
Ruben Verresen, Umberto Borla, Ashvin Vishwanath +2
Where in the landscape of many-body phases of matter do we place the Higgs condensate of a gauge theory? On the one hand, the Higgs phase is gapped, has no local order parameter, a…
Boundary deconfined quantum criticality at transitions between symmetry-protected topological chains
Saranesh Prembabu, Ryan Thorngren, Ruben Verresen
Decades of research have revealed a deep understanding of topological quantum matter with protected edge modes. We report that even richer physics emerges when tuning between two t…
