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…
