Interplay between exotic superfluidity and magnetism in a chain of four-component ultracold atoms
E. Szirmai, G. Barcza, J. Sólyom +1
We investigate the spin-polarized chain of ultracold fermionic atoms with spin-3/2 described by the fermionic Hubbard model with SU(4) symmetric attractive interaction. The competi…
Entanglement structure of the Hubbard model in momentum space
G. Ehlers, J. Sólyom, Ö. Legeza +1
We study the properties of the ground states of the one- and two-dimensional Hubbard models at half filling and moderate doping using entanglement-based measures, which we calculat…
Momentum distribution functions in a one-dimensional extended periodic Anderson model
I. Hagymasi, J. Solyom, O. Legeza
We study the momentum distribution of the electrons in an extended periodic Anderson model, where the interaction, , between itinerant and localized electrons is taken into…
Competition between Hund's coupling and Kondo effect in a one-dimensional extended periodic Anderson model
I. Hagymasi, J. Solyom, O. Legeza
We study the ground-state properties of an extended periodic Anderson model to understand the role of Hund's coupling between localized and itinerant electrons using the density-ma…
