Lieb-Schultz-Mattis theorem from gauge constraints
Bhandaru Phani Parasar
We construct a gauge theory coupled to matter on a one-dimensional chain, aiming to study the ground-state physics in the Gauss law subspace. We…

Fractons on the edge
Bhandaru Phani Parasar, Yuval Gefen, Vijay B. Shenoy
We develop a theory of edge excitations of fractonic systems in two dimensions, and elucidate their connections to bulk transport properties and quantum statistics of bulk excitati…

Hopf Semimetals
Bhandaru Phani Parasar, Vijay B. Shenoy
We construct two-band topological semimetals in four dimensions using the unstable homotopy of maps from the three-torus (Brillouin zone of a 3D crystal) to the two-sphere $S…
