Global anomalies of Green's function zeros
Lei Su, Ivar Martin
We study global anomalies of nonlocal effective theories proposed to describe symmetry-preserving Luttinger surfaces, i.e., the momentum-space manifolds of Green's function zeros (…

Gapless symmetry-protected topological phases and generalized deconfined critical points from gauging a finite subgroup
Lei Su, Meng Zeng
Gauging a finite subgroup of a global symmetry can map conventional phases and phase transitions to unconventional ones. In this work, we study, as a concrete example, an emergent…
