Entanglement in the ground state of clusters joined by a single bond
Barry Friedman, Alyssa Horne
The ground state of an antiferromagnetic Heisenberg model on L X L clusters joined by a single bond and balanced Bethe clusters are investigated with quantum Monte Carlo and modifi…
Short and Long Ranged Impurities in Fractional Quantum Hall Systems
Barry Friedman
Short and long-range impurities have been examined for fractional quantum Hall systems. There appears to be a consistent computational picture for short range impurities. In the ca…
Entanglement Entropy of Quantum Hall Systems at Half Filling
C. Balusek, B. A. Friedman, G. C. Levine +1
The entanglement entropy of and quantum Hall states in the presence of short range disorder has been calculated by direct diagonalization. Spin polarized electrons…
Projective approach to the entanglement entropy of 1- fermions
G. C. Levine, B. A. Friedman
The entanglement entropy of two gapless non-interacting fermion subsystems is computed approximately in a way that avoids the introduction of replicas and a geometric interpretatio…
Topological entanglement entropy in the second Landau level
B. A. Friedman, G. C. Levine
The entanglement entropy of the incompressible states of a realistic quantum Hall system in the second Landau level are studied by direct diagonalization. The subdominant term to t…
Topological entropy of realistic quantum Hall wave functions
B. A. Friedman, G. C. Levine
The entanglement entropy of the incompressible states of a realistic quantum Hall system are studied by direct diagonalization. The subdominant term to the area law, the topologica…
