Real-time dynamics of particle-hole excitations in Mott insulator-metal junctions
Luis G. G. V. Dias da Silva, Khaled A. Al-Hassanieh, Adrian E. Feiguin +2
Charge excitations in Mott insulators (MIs) are distinct from their band-insulator counterparts and they can provide a mechanism for energy harvesting in solar cells based on stron…
Three orbital model for the iron-based superconductors
Maria Daghofer, Andrew Nicholson, Adriana Moreo +1
The theoretical need to study the properties of the Fe-based high-T_c superconductors with reliable many-body techniques requires us to determine the minimum number of orbital degr…
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 …
Electron-lattice coupling and partial nesting as the origin of Fermi-Arcs in manganites
Juan Salafranca, Gonzalo Alvarez, Elbio Dagotto
A tight-binding model for eg electrons coupled to Jahn-Teller lattice distortions is studied via unbiased Monte- Carlo simulations. By focusing on the periodicity of the Jahn Telle…
Double-exchange model study of multiferroic MnO perovskites

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…
Electronic and Magnetic Properties of Heterostructures
Rong Yu, Seiji Yunoki, Shuai Dong +1
In this paper, we investigate the ground state properties of the () heterostructures (R=trivalent cation, and A=divalent cation) by using a…
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…
Quantum distillation: dynamical generation of low-entropy states of strongly correlated fermions in an optical lattice
F. Heidrich-Meisner, S. R. Manmana, M. Rigol +3
Correlations between particles can lead to subtle and sometimes counterintuitive phenomena. We analyze one such case, occurring during the sudden expansion of fermions in a lattice…
Phonon-assisted tunneling and two-channel Kondo physics in molecular junctions
Luis G. Dias da Silva, Elbio Dagotto
The interplay between vibrational modes and Kondo physics is a fundamental aspect of transport properties of correlated molecular conductors. We present theoretical results for a s…
