Cellular Dynamical Mean Field Approach to Strongly Correlated Systems
Gabriel Kotliar, Sergej Y. Savrasov, Gunnar Palsson
We propose a cellular version of dynamical-mean field theory which gives a natural generalization of its original single-site construction and is formulated in different sets of va…
Metal-insulator and magnetic collapse transitions in FeO at high pressure: predictions of the LDA+U method
S. A. Gramsch, R. E. Cohen, S. Y. Savrasov
The accuracy of LDA + U total energies is tested by predicting the high pressure behavior of rocksalt-structured FeO, including metal-insulator and magnetic transitions, equation o…
Importance of Correlation Effects on Magnetic Anisotropy in Fe and Ni
Imseok Yang, Sergej Y. Savrasov, Gabriel Kotliar
We calculate magnetic anisotropy energy of Fe and Ni by taking into account the effects of strong electronic correlations, spin-orbit coupling, and non-collinearity of intra-atomic…
