• Beating of Friedel oscillations induced by spin-orbit interaction 

    Badalyan, S. M.; Matos-Abiague, A.; Vignale, Giovanni, 1957-; Fabian, J. (American Physical Society, 2010-05)
    By exploiting our recently derived exact formula for the Lindhard polarization function in the presence of Bychkov-Rashba (BR) and Dresselhaus (D) spin-orbit interaction (SOI), we show that the interplay of different SOI ...
  • Density‐functional studies of the electronic structure of the perovskite oxides: La1−xCaxMnO3 

    Satpathy, Sashi Sekhar, 1956-; Popovic, Zoran S.; Vukajlovic, Filip R. (American Institute of Physics, 1996-04)
    Using density‐functional methods, we study the electronic structures of the lanthanum‐based ''double‐exchange'' perovskite magnets. Antiferromagnetic insulating solutions are obtained for both the end members, LaMnO3 and ...
  • Jahn-Teller coupling and double exchange in the two-site Van Vleck-Kanamori model 

    Meskine, Hakim, 1972-; Satpathy, Sashi Sekhar, 1956- (American Institute of Physics, 1999-04)
    The effect of the dynamical Jahn-Teller coupling on the Anderson-Hasegawa double exchange (DE) in the manganites is studied in a two-site model taking into account the double degeneracy of the eg orbitals and their coupling ...
