: An open-source quantum impurity solver package based on the natural orbitals renormalization group
Jia-Ming Wang, Yi-Heng Tian, Yin Chen +3
In the context of dynamical mean-field theory (DMFT) calculations for strongly correlated electron systems, quantum impurity solvers play a central computational role in treating c…
Spin-orbit coupling effects on orbital-selective correlations in a three-orbital model
Yin Chen, Yi-Heng Tian, Rong-Qiang He +1
In ruthenate materials, non-Fermi liquid (NFL) phases have been observed. We used the natural orbitals renormalization group (NORG) method as an impurity solver for dynamical mean-…
Non-Fermi liquid and antiferromagnetic correlations with hole doping in the bilayer two-orbital Hubbard model of LaNiO at zero temperature
Yin Chen, Yi-Heng Tian, Jia-Ming Wang +2
High- superconductivity (SC) was recently found in the bilayer material LaNiO (La327) under high pressures. We study the bilayer two-orbital Hubbard model derived…
Low-energy interband Kondo bound states in orbital-selective Mott phases
Jia-Ming Wang, Yin Chen, Yi-Heng Tian +2
Low-energy excitations in correlated electron systems may show intricate behaviors and provide essential insights into the dynamics of quantum states and phase transitions. Here, w…
Solving multiorbital dynamical mean-field theory using natural orbitals renormalization group
Jia-Ming Wang, Yin Chen, Yi-Heng Tian +2
The natural orbitals renormalization group (NORG) has previously been proposed as an efficient numerical method for solving zero-temperature properties of multisite and multiorbita…
