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…

Auxiliary dynamical mean-field approach for Anderson-Hubbard model with off-diagonal disorder
Zelei Zhang, Jiawei Yan, Li Huang +1
This work reports a theoretical framework that combines the auxiliary coherent potential approximation (ACPA-DMFT) with dynamical mean-field theory to study strongly correlated and…

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…
