Magnetic polaron structures in the one-dimensional double and super-exchange model
E. Vallejo, F. López-Urías, O. Navarro +1
An analytical and numerical study of the one-dimensional double and super-exchange model is presented. A phase separation between ferromagnetic and anti-ferromagnetic phases occurs…

Spin-polarons in an exchange model
O. Navarro, E. Vallejo, M. Avignon
Spin-polarons are obtained using an Ising-like exchange model consisting of double and super-exchange interactions in low dimensional systems. At zero temperature, a new phase sepa…

Electron pairing in one-dimensional quasicrystals
Y. Arredondo, O. Navarro
Electron pairing in one-dimensional binary Hubbard chains is studied for different values of the band-filling using the Density Matrix Renormalization Group method. The systems con…
