Formal Green's function theory in non-Hermitian lattice systems
Changrui Chen, Wenan Guo
In this paper, we employ the generalized Bloch theory to rediscover the generalized Brillouin zone theory and follow this way to obtain the Green's function of the non-Hermitian sy…

Primary and Secondary Order Parameters in the Fully Frustrated Transverse Field Ising Model on the Square Lattice
Gabe Schumm, Hui Shao, Wenan Guo +2
Using quantum Monte Carlo simulations and field-theory arguments, we study the fully frustrated (Villain) transverse-field Ising model on the square lattice. We consider a "primary…
