Fractals and spontaneous symmetry breaking with type-B Goldstone modes: a perspective from entanglement
Huan-Qiang Zhou, Qian-Qian Shi, John O. Fjærestad +1
The one-dimensional spin- ferromagnetic Heisenberg model, as a paradigmatic example for spontaneous symmetry breaking (SSB) with type-B Goldstone modes (GMs), is e…

Staggered orbital currents in the half-filled two-leg ladder
J. O. Fjaerestad, J. B. Marston
Using Abelian bosonization with a careful treatment of the Klein factors, we show that a certain phase of the half-filled two-leg ladder, previously identified as having spin-Peier…

Correlation functions for a two-dimensional electron system with bosonic interactions and a square Fermi surface
J. O. Fjaerestad, A. Sudbo, A. Luther
We calculate zero-temperature correlation functions for a model of 2D interacting electrons with short-range interactions and a square Fermi surface. The model was arrived at by ma…
