Non-invertible Lattice 1-Form Symmetries for Non-Abelian Topological Order
Rafael Flores-Calderón, Frank Pollmann, Michael Knap
Higher-form symmetries generalize conventional global symmetries and act on lower-dimensional submanifolds of a quantum system. While Abelian topological phases can be organized by…

Unconventional Spin Dynamics and Supersolid Excitations in the Triangular-Lattice XXZ Model
Rafael Flores-Calderón, Roderich Moessner, Frank Pollmann
Motivated by recent experiments, we investigate the spin-1/2 XXZ model on the triangular lattice with strong Ising anisotropy, combining large-scale numerical simulations and analy…

Effective field theory of the quantum skyrmion Hall effect
Vinay Patil, Rafael Flores-Calderón, Ashley M. Cook
Motivated by phenomenology of myriad recently-identified topologically non-trivial phases of matter, we introduce effective field theories (EFTs) for the quantum skyrmion Hall effe…
