Validity and Limits of Low Order Hybridization Expansion Approaches for Multi-Orbital Systems
Dolev Goldberger, Ido Zemach, Lei Zhang +4
Low-order hybridization expansion methods such as the non-crossing approximation (NCA) and the one-crossing approximation (OCA) are widely used impurity solvers in the study of str…

Dynamical Mean Field Theory of the Bilayer Hubbard Model with Inchworm Monte Carlo
Dolev Goldberger, Yehonatan Fridman, Emanuel Gull +2
Dynamical mean-field theory allows access to the physics of strongly correlated materials with nontrivial orbital structure, but relies on the ability to solve auxiliary multi-orbi…
