Weak in the boundary: How weak SPT phases spoil anomaly matching
Daniel Sheinbaum, Omar Antolín Camarena
We show how weak symmetry protected topological (SPT) phases on systems with a boundary are not in 1-to-1 correspondence with weak SPT phases on fully periodic systems, breaking th…
Weak topological phases in the presence of interactions
Omar Antolín Camarena, Arun Debray, Cameron Krulewski +3
We study weak symmetry-protected topological phases (SPTs) in the presence of short-range interactions. By comparing homotopical free and interacting classifications of these SPTs,…
A Center Transversal Theorem for mass assignments
Omar Antolín Camarena, Jaime Calles Loperena
In this paper, based on the ideas of Blagojević, Karasev & Magazinov, we consider an extension of the center transversal theorem to mass assignments with an improved Rado depth. In…
Homotopy type of the independence complex of some categorical products of graphs
Omar Antolín Camarena, Andrés Carnero Bravo
It was conjectured by Goyal, Shukla and Singh that the independence complex of the categorical product has the homotopy type of a wedge of s…
