Simple Fermionic Model of Deconfined Phases and Phase Transitions
Simple Fermionic Model of Deconfined Phases and Phase Transitions
Using Quantum Monte Carlo simulations, we study a series of models of fermions coupled to quantum Ising spins on a square lattice with $N$ flavors of fermions per site for $N=1,2$ and $3$. The models have an extensive number of conserved quantities but are not integrable, and have rather rich …
