Excitonic correlations in the equilibrium and voltage-biased bilayer Hubbard model: multi-orbital two-particle self-consistent approach
Jiawei Yan, Jonas B. Profe, Yuta Murakami +1
We develop a nonequilibrium multi-orbital extension of the two-particle self-consistent theory and apply it to the bilayer Hubbard model as a minimal platform to investigate correl…

Multi-orbital two-particle self-consistent approach -- strengths and limitations
Jonas B. Profe, Jiawei Yan, Karim Zantout +2
Extending many-body numerical techniques which are powerful in the context of simple model calculations to the realm of realistic material simulations can be a challenging task. Re…

Real-frequency TPSC+DMFT investigation of the square-lattice Hubbard model
Lei Geng, Jiawei Yan, Philipp Werner
We investigate the two-dimensional Hubbard model using a real-frequency implementation of the TPSC+DMFT approach. This hybrid method combines the nonlocal correlations captured by…
