Chiral Long-Range Order in three Euclidean Lattice Gross-Neveu Models

Simone Fabbri, Leonardo Goller

We prove the existence of Long-Range Order in a class of two-dimensional Euclidean lattice Gross-Neveu models with an even number of fermion flavors, covering three standard lattic…

Anyons in the $I ¨ $ -flux phase of fermionic matter coupled to a $Z_{2}$ -gauge field

Sven Bachmann, Leonardo Goller, Marcello Porta

We consider a system of weakly interacting spinful lattice fermions coupled to a dynamical $Z_{2}$ gauge field. Using reflection positivity, we prove that the ground state l…

Stability of the $I ¨ $ -Flux Phase for $Z_{2}$ Lattice Gauge Theory Coupled to Fermionic Matter

Leonardo Goller, Marcello Porta

We consider the two-dimensional $Z_{2}$ Ising gauge theory coupled to fermionic matter. In absence of electric fields, we prove that, at half-filling, the ground state of…
