Collective Modes in Excitonic Magnets: Dynamical Mean-Field Study
D. Geffroy, J. Kaufmann, A. Hariki +3
We present a dynamical mean-field study of dynamical susceptibilities in two-band Hubbard model. Varying the model parameters we analyze the two-particle excitations in the normal…
State- and superstate-sampling in hybridization-expansion continuous-time quantum Monte Carlo
Alexander Kowalski, Andreas Hausoel, Markus Wallerberger +2
Due to the intrinsic complexity of the quantum many-body problem, quantum Monte Carlo algorithms and their corresponding Monte Carlo configurations can be defined in various ways.…
Impact of self-consistency in dual fermion calculations
Tin Ribic, Patrik Gunacker, Karsten Held
The dual fermion (DF) method allows for calculating corrections due to non-local correlations relative to an effective impurity model. Choosing the impurity as that of a dynamical…
