Topologically Obstructed Superconducting Order
Canon Sun, Yi Li
We propose a class of topological superconductivity in which the pairing order is topologically obstructed in a three-dimensional time-reversal invariant system. Whe…

Vortices in a Monopole Superconducting Weyl Semi-metal
Canon Sun, Shu-Ping Lee, Yi Li
A monopole harmonic superconductor is a novel topological phase of matter with topologically protected gap nodes that result from the non-trivial Berry phase structure of Cooper pa…

Monopole Charge Density Wave States in Weyl Semimetals
Eric Bobrow, Canon Sun, Yi Li
We study a new class of topological charge density wave states exhibiting monopole harmonic symmetries. The density-wave ordering is equivalent to pairing in the particle-hole chan…
