SO(5) Superconductors in a Zeeman Magnetic Field
Jiang-Ping Hu, Shou-Cheng Zhang
The generic symmetry of a system under a uniform Zeeman magnetic field is U(1) x U(1). However, we show that SO(5) models in the presence of a finite chemical potential and a finit…

Projected SO(5) Models
Shou-Cheng Zhang, Jiang-Ping Hu, Enrico Arrigoni +2
We construct a class of projected SO(5) models where the Gutzwiller constraint of no-double-occupancy is implemented exactly. We introduce the concept of projected SO(5) symmetry w…
