Momentum distribution in two-orbital Hubbard model: Quantum Monte Carlo approach
- 1. National Research Nuclear University MEPhI (Moscow Engineering Physics Institute), Kashirskoe sh. 31, 115409 Moscow (Russian Federation)
Description
The two-dimensional two-orbital Hubbard model is studied with the use of worldline quantum Monte Carlo algorithm. Spectral functions and the density of states for various parameters of the model are obtained in both the undoped and low-doped regimes. The invariance of the Fermi surface with respect to the strength of the interaction is testified. Fermi-liquid parameters of the model are derived. (paper)
