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…
On the universality class of the Mott transition in two dimensions
S. Moukouri, Eitan Eidelstein
We use the two-step density-matrix renormalization group method to elucidate the long-standing issue of the universality class of the Mott transition in the Hubbard model in two di…
Hybrid NRG-DMRG approach to real-time dynamics of quantum impurity systems
Fabian Guettge, Frithjof B. Anders, Ulrich Schollwoeck +2
A hybrid approach to nonequilibrium dynamics of quantum impurity systems is presented. The numerical renormalization group serves as a means to generate a suitable low-energy Hamil…
Mott Transition in Quasi-One-Dimensional Systems
S. Moukouri, Eitan Eidelstein
We report the application of the density-matrix renormalization group method to a spatially anisotropic two-dimensional Hubbard model at half-filling. We find a deconfinement trans…
Quantum phase transitions, frustration, and the Fermi surface in the Kondo lattice model
Eitan Eidelstein, S. Moukouri, Avraham Schiller
The quantum phase transition from a spin-Peierls phase with a small Fermi surface to a paramagnetic Luttinger-liquid phase with a large Fermi surface is studied in the framework of…
A two-step density-matrix renormalization-group study of coupled Luttinger liquids
S. Moukouri, E. Eidelstein
We report a two-step density-matrix renormalization-group computation of the equal-time single-particle Green's function, the density-density correlations, and the low-frequency sp…
