Ground-State Degeneracy of Correlated Insulators with Edges
Gil Refael, Hsiu-Hau Lin
Using the topological flux insertion procedure, the ground-state degeneracy of an insulator on a periodic lattice with filling factor was found to be at least -fold. App…

Phonons in Hubbard ladders studied within the framework of the one-loop renormalization group
Alexander Seidel, Hsiu-Hau Lin, Dung-Hai Lee
We study the effects of phonons in -leg Hubbard ladders within the framework of a one-loop renormalization group. In particular, we explicitly demonstrate that the role of phono…
