Quench dynamics of Anderson impurity model using configuration interaction method
Chungwei Lin, Alexander A. Demkov
We study the quench dynamics of an Anderson impurity model using the configuration interaction (CI) method. In particular, we focus on the relaxation behavior of the impurity occup…
Final-state effect on x-ray photoelectron spectrum of nominally and -doped transition metal oxides
Chungwei Lin, Agham Posadas, Tobias Hadamek +1
We investigate the x-ray photoelectron spectroscopy (XPS) of nominally and -doped transition metal oxides including NbO, SrVO, and LaTiO (nominally …
Electron Correlation in Oxygen Vacancy in SrTiO
Chungwei Lin, Alexander A. Demkov
Oxygen vacancies are an important type of defect in transition metal oxides. In SrTiO they are believed to be the main donors in an otherwise intrinsic crystal. At the same tim…
Efficient variational approach to the impurity problem and its application to the dynamical mean-field theory
Chungwei Lin, Alexander A. Demkov
Within the framework of exact diagonalization (ED), we compute the ground state of Anderson impurity problem using the variational approach based on the configuration interaction (…
Lattice distortion effects on topological phases in (LaNiO)/(LaAlO) heterostructures grown along the [111] direction
Andreas Rüegg, Chandrima Mitra, Alexander A. Demkov +1
We theoretically investigate the influence of internal and external strain on topological phases in (LaNiO)/(LaAlO) heterostructures grown along the [111] direction…
Electronic structure of (LaNiO)/(LaAlO) heterostructures grown along [111]
Andreas Rüegg, Chandrima Mitra, Alexander A. Demkov +1
The electronic structure of a LaNiO bilayer grown along the [111] direction and confined between insulating layers of LaAlO is theoretically investigated using a combinatio…
