Title: Frustration-free Hamiltonian with Topological Order on Graphs

Authors: Pramod Padmanabhan, Jintae Kim, Jung Hoon Han

Comments: The paper was written in a manner making it prone to misinterpretation. These models are inspired by higher gauge theories as elaborated in 1907.01608v2 making them similar to the toric code. The ground states have topological entanglement entropy which is accounted for by anyonic excitations. A more comprehensive version will appear in a fresh submission by one of the authors, PP
