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…
Doped orbitally-ordered systems: another case of phase separation
K. I. Kugel, A. L. Rakhmanov, A. O. Sboychakov +1
A possible mechanism of electronic phase separation in the systems with orbital ordering is analyzed. We suggest a simple model taking into account an interplay between the delocal…
Negative differential resistivity in superconductors with periodic arrays of pinning sites
V. R. Misko, S. Savel'ev, A. L. Rakhmanov +1
We study theoretically the effects of heating on the magnetic flux moving in superconductors with a periodic array of pinning sites (PAPS). The voltage-current characteristic (VI-c…
