Boundary effects in the critical scaling of entanglement entropy in 1D systems
Nicolas Laflorencie, Erik S. Sorensen, Ming-Shyang Chang +1
We present exact diagonalization and density matrix renormalization group results for the entanglement entropy of critical spin-1/2 XXZ chains. We find that open boundary condition…
Applications of Cluster Perturbation Theory Using Quantum Monte Carlo Data
Fei Lin, Erik S. Sorensen, Catherine Kallin +1
We study cluster perturbation theory [Phys. Rev. Lett. \textbf{84}, 522 (2000)] when auxiliary field quantum Monte Carlo method is used for solving the cluster hamiltonian. As a ca…
Universal Scaling of the Conductivity at the Superfluid-Insulator Phase Transition
Jurij Smakov, Erik Sorensen
The scaling of the conductivity at the superfluid-insulator quantum phase transition in two dimensions is studied by numerical simulations of the Bose-Hubbard model. In contrast to…
