A continuous Mott transition between a metal and a quantum spin liquid
Ryan V. Mishmash, Ivan Gonzalez, Roger G. Melko +2
More than half a century after first being proposed by Sir Nevill Mott, the deceptively simple question of whether the interaction-driven electronic metal-insulator transition may…
Non-equilibrium electronic transport in a one-dimensional Mott insulator
F. Heidrich-Meisner, I. Gonzalez, K. A. Al-Hassanieh +3
We calculate the non-equilibrium electronic transport properties of a one-dimensional interacting chain at half filling, coupled to non-interacting leads. The interacting chain is…
Measuring Renyi Entanglement Entropy with Quantum Monte Carlo
Matthew B. Hastings, Ivan Gonzalez, Ann B. Kallin +1
We develop a quantum Monte Carlo procedure, in the valence bond basis, to measure the Renyi entanglement entropy of a many-body ground state as the expectation value of a unitary {…
Valence Bond and von Neumann Entanglement Entropy in Heisenberg Ladders
Ann B. Kallin, Ivan Gonzalez, Matthew B. Hastings +1
We present a direct comparison of the recently-proposed valence bond entanglement entropy and the von Neumann entanglement entropy on spin 1/2 Heisenberg systems using quantum Mont…
Excitons in the One-Dimensional Hubbard Model: a Real-Time Study
K. A. Al-Hassanieh, F. A. Reboredo, A. E. Feiguin +2
We study the real-time dynamics of a pair hole/doubly-occupied-site, namely a holon and a doublon, in a 1D Hubbard insulator with on-site and nearest-neighbor Coulomb repulsion. Ou…
Stabilization of magnetic polarons in antiferromagnetic semiconductors by extended spin distortions
J. Castro, I. Gonzalez, D. Baldomir
We study the problem of a magnetic polaron in an antiferromagnetic semiconductor (ferron). We obtain an analytical solution for the distortion produced in the magnetic structure of…
