Spontaneously Broken Non-Invertible Symmetries in Transverse-Field Ising Qudit Chains
Kristian Tyn Kai Chung, Umberto Borla, Andriy H. Nevidomskyy +1
Recent developments have revealed that symmetries need not form a group, but instead can be non-invertible. Here we use analytical arguments and numerical evidence to illuminate ho…

Geometrically Frustrated Quadrupoles on the Pyrochlore Lattice and Generalized Spin Liquids
Kristian Tyn Kai Chung, Sylvain Petit, Julien Robert +1
As an instance of geometrical frustration with non-magnetic degrees of freedom, we explore the physics of local spin moments on the pyrochlore lattice that interact via p…
