Quantum-embedding description of the Anderson lattice model with the ghost Gutzwiller Approximation
Marius S. Frank, Tsung-Han Lee, Gargee Bhattacharyya +5
We present benchmark calculations of the Anderson lattice model based on the recently-developed "ghost Gutzwiller approximation". Our analysis shows that, in some parameters regime…
Unusually thick metal-insulator domain walls around the Mott point
M. Y. Suárez-Villagrán, N. Mitsakos, Tsung-Han Lee +3
Many Mott systems feature a first-order metal-insulator transition at finite temperatures, with an associated phase coexistence region displaying inhomogeneities and local phase se…
Bypassing the computational bottleneck of quantum-embedding theories for strong electron correlations with machine learning
John Rogers, Tsung-Han Lee, Sahar Pakdel +5
A cardinal obstacle to performing quantum-mechanical simulations of strongly-correlated matter is that, with the theoretical tools presently available, sufficiently-accurate comput…
Hybridization effect on the X-ray absorption spectra for actinide materials: Application to PuB
Wei-ting Chiu, Roxanne M. Tutchton, Giacomo Resta +5
Studying the local moment and 5-electron occupations sheds insight into the electronic behavior in actinide materials. X-ray absorption spectroscopy (XAS) has been a powerful to…
The two-dimensional disordered Mott metal-insulator transition
M. Y. Suárez-Villagrán, N. Mitsakos, Tsung-Han Lee +3
We studied several aspects of the Mott metal-insulator transition in the disordered case. The model on which we based our analysis is the disordered Hubbard model, which is the sim…
Rotationally invariant slave-boson and density matrix embedding theory: A unified framework and a comparative study on the 1D and 2D Hubbard Model
Tsung-Han Lee, Thomas Ayral, Yong-Xin Yao +2
We present detailed benchmark ground-state calculations of the one- and two-dimensional Hubbard model utilizing the cluster extensions of the rotationally invariant slave-boson (RI…
