A model for the phase separation controlled by doping and the internal chemical pressure in different cuprate superconductors
K. I. Kugel, A. L. Rakhmanov, A. O. Sboychakov +2
In the framework of a two-band model, we study the phase separation regime of different kinds of strongly correlated charge carriers as a function of the energy splitting between t…

Trapping of lattice polarons by impurities
J. P. Hague, P. E. Kornilovitch, A. S. Alexandrov
We consider the effects of single impurities on polarons in three-dimensions (3D) using a continuous time quantum Monte-Carlo algorithm. An exact treatment of the phonon degrees of…

Self-organization of charged particles on a 2D lattice subject to anisotropic Jahn-Teller-type interaction and 3D Coulomb repulsion
T. Mertelj, V. V. Kabanov, J. Miranda +1
Self-organization of charged particles on a 2D lattice, subject to an anisotropic Jahn-Teller-type interaction and 3D Coulomb repulsion is investigated. In the mean-field approxima…
