Continuous-time auxiliary field Monte Carlo for quantum impurity models
Emanuel Gull, Philipp Werner, Olivier Parcollet +1
We present a continuous-time Monte Carlo method for quantum impurity models, which combines a weak-coupling expansion with an auxiliary-field decomposition. The method is considera…
Effect of Crystal-Field Splitting and Inter-Band Hybridization on the Metal-Insulator Transitions of Strongly Correlated Systems
Alexander I. Poteryaev, Michel Ferrero, Antoine Georges +1
We investigate a quarter-filled two-band Hubbard model involving a crystal-field splitting, which lifts the orbital degeneracy as well as an inter-orbital hopping (inter-band hybri…
Nodal/Antinodal Dichotomy and the Two Gaps of a Superconducting Doped Mott Insulator
M. Civelli, M. Capone, A. Georges +4
We study the superconducting state of the hole-doped two-dimensional Hubbard model using Cellular Dynamical Mean Field Theory, with the Lanczos method as impurity solver. In the un…
Quantum melting of a crystal of dipolar bosons
Christophe Mora, Olivier Parcollet, Xavier Waintal
We investigate the behaviour of dipolar bosons in two dimensions. We describe the large density crystalline limit analytically while we use quantum Monte-Carlo to study the melting…
Schwinger Boson approach to the fully screened Kondo model
J. Rech, P. Coleman, G. Zarand +1
We apply the Schwinger boson scheme to the fully screened Kondo model and generalize the method to include antiferromagnetic interactions between ions. Our approach captures the Ko…
