Exact fermionic dual of the Bose-Hubbard model
Lei Su, Ivar Martin, Aashish A. Clerk
Recent developments have established exact bosonization and fermionization with a symmetry as dualities through gauging. In this work, we apply fermionic gauging, wh…
Bosonization and Kramers-Wannier dualities in general dimensions
Lei Su, Ivar Martin
It is well known that the noninteracting Majorana chain is dual to the one-dimensional transverse-field Ising model, either through the Jordan-Wigner transformation or by gauging f…
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…
