Correlated adatom trimer on metal surface: A continuous time quantum Monte Carlo study
V. V. Savkin, A. N. Rubtsov, M. I. Katsnelson +1
The problem of three interacting Kondo impurities is solved within a numerically exact continuous time quantum Monte Carlo scheme. A suppression of the Kondo resonance by interatom…

Continuous Time Quantum Monte Carlo method for fermions
A. N. Rubtsov, V. V. Savkin, A. I. Lichtenstein
We present numerically exact continuous-time Quantum Monte Carlo algorithm for fermions with a general non-local in space-time interaction. The new determinantal grand-canonical sc…

Continuous Time Quantum Monte Carlo Method for Fermions: Beyond Auxiliary Field Framework
A. N. Rubtsov, A. I. Lichtenstein
Numerically exact continuous-time Quantum Monte Carlo algorithm for finite fermionic systems with non-local interactions is proposed. The scheme is particularly applicable for gene…
