Bosonic Fractional Quantum Hall States on a Finite Cylinder

11 Mar 2019 Rosson Paolo Lubasch Michael Kiffner Martin Jaksch Dieter

We investigate the ground state properties of a bosonic Harper-Hofstadter model with local interactions on a finite cylindrical lattice with filling fraction $\nu=1/2$. We find that our system supports topologically ordered states by calculating the topological entanglement entropy, and its value is in good agreement with the theoretical value for the $\nu=1/2$ Laughlin state...
