Counting Edge Modes with the Higher Berry Curvature: A Bulk Topological Order Parameter for Quantum Spin Chains
Adam J. McRoberts, Joe Crossley, Chris Hooley +1
We show that the higher Berry curvature (HBC) can be used to count the gapless edge modes created by an entanglement cut, and thus defines an integer-valued topological order param…
A Generalised Haldane Map from the Matrix Product State Path Integral to the Critical Theory of the - Chain
F. Azad, Adam J. McRoberts, Chris Hooley +1
We study the - spin- chain using a path integral constructed over matrix product states (MPS). By virtue of its non-trivial entanglement structure, the MPS ansatz ca…
Intermediate-scale theory for electrons coupled to frustrated local-moments
Adam J. McRoberts, J. F. Mendez-Valderrama, Roderich Moessner +1
A classic route for destroying long-lived electronic quasiparticles in a weakly interacting Fermi liquid is to couple them to other low-energy degrees of freedom that effectively a…
