Multiorbital Hubbard model in infinite dimensions: Quantum Monte Carlo calculation
Using the quantum Monte Carlo technique we compute thermodynamics and spectra for the orbitally degenerate Hubbard model in infinite spatial dimensions. With increasing orbital degeneracy we find in the one-particle spectra broader Hubbard bands ~consistent with increased kinetic energy!, a narrowing Mott gap, and increasing quasiparticle spectral weight. Hund’s rule exchange coupling decreases...

متن کاملSpin-boson coupling in continuous-time quantum Monte Carlo
A vector bosonic field coupled to the electronic spin is treated by means of the continuous-time quantum Monte Carlo method. In the Bose-Kondo model with a sub-Ohmic density of states ρB(ω) ∝ ω with s = 0.2, two contributions to the spin susceptibility, the Curie term T −1 and the term T −s due to bosonic fluctuations, are observed separately. This result indicates the existence of a residual m...
متن کاملContinuous-time Monte Carlo methods for quantum impurity models
Quantum impurity models describe an atom or molecule embedded in a host material with which it can exchange electrons. They are basic to nanoscience as representations of quantum dots and molecular conductors and play an increasingly important role in the theory of “correlated electron” materials as auxiliary problems whose solution gives the “dynamical mean field” approximation to the self ene...
متن کاملContinuous-time auxiliary field Monte Carlo for quantum impurity models
Introduction. – The development of efficient numerical methods for solving quantum impurity models has been driven in recent years by the success of dynamical mean field theory (DMFT) [1–3] and its extensions. DMFT is an approximate framework for the study of fermionic lattice models, which replaces the lattice by a quantum impurity embedded in a self-consistent bath. Both cluster-extensions of...
