Metal-insulator transition in the hybridized two-orbital Hubbard model revisited
Y. Nunez-Fernandez, K. Hallberg
In this work we study the two-orbital Hubbard model on a square lattice in the presence of hybridization between nearest-neighbor orbitals and a crystal-field splitting. We use a h…

Emergent low-energy bound states in the two-orbital Hubbard model
Y. Nunez-Fernandez, G. Kotliar, K. Hallberg
A repulsive Coulomb interaction between electrons in different orbitals in correlated materials can give rise to bound quasiparticle states. We study the non-hybridized two-orbital…

Superfluidity and collective oscillations of trapped Bose-Einstein condensates in a periodical potential
C. Trallero-Giner, V. Lopez-Richard, Y. Núñez-Fernández +2
Based on a unified theoretical treatment of the 1D Bogoliubov-de Genes equations, the superfluidity phenomenon of the Bose-Einstein condensates (BEC) loaded into trapped optical la…
