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…

Origin of the intermediate-temperature magnetic specific heat capacity in the spin-liquid candidate CaCrO
Joe Crossley, Chris Hooley
We present several approximate calculations of the specific heat capacity of the model for CaCrO proposed by Balz et al. [Phys. Rev. B 95, 174414 (2017)], using m…
