Exchange bias driven by the Dzyaloshinskii-Moriya interaction and ferroelectric polarization at G-type antiferromagnetic perovskite interfaces
Shuai Dong, Kunihiko Yamauchi, Seiji Yunoki +6
Exchange bias is usually rationalized invoking spin pinning effects caused by uncompensated antiferromagnetic interfaces. However, for compensated antiferromagnets other extrinsic…
Electronic self-organization in the single-layer manganite
F. Ye, Songxue Chi, J. A. Fernandez-Baca +7
We use neutron scattering to investigate the doping evolution of the magnetic correlations in the single-layer manganite , away from the …
On interband pairing in multiorbital systems
Adriana Moreo, Maria Daghofer, Andrew Nicholson +1
The discovery of high- superconductivity in the pnictides, materials with a Fermi surface determined by several bands, highlights the need to understand how superconductivity…
Striped Multiferroic Phase in Double-Exchange Model for Quarter-Doped Manganites
Shuai Dong, Rong Yu, J. -M. Liu +1
The phase diagram of quarter-hole-doped perovskite manganites is investigated using the doubleexchange model. An exotic striped type-II multiferroic phase, where 25% of the nearest…
Many-body electronic structure and Kondo properties of cobalt-porphyrin molecules
Luis G. G. V. Dias da Silva, Murilo L. Tiago, Sergio E. Ulloa +2
We use a combination of first principles many-body methods and the numerical renormalization-group technique to study the Kondo regime of cobalt-porphyrin compounds adsorbed on a C…
Real-time simulations of nonequilibrium transport in the single-impurity Anderson model
F. Heidrich-Meisner, A. E. Feiguin, E. Dagotto
One of the main open problems in the field of transport in strongly interacting nanostructures is the understanding of currents beyond the linear response regime. In this work, we…
