Nanoscale layering antiferromagnetic superconducting phases Rb2Fe4Se5
2012/2/27
We studied phase separation in a single-crystalline antiferromagnetic superconductor Rb2Fe4Se5 (RFS) using a combination of scattering-type scanning near-field optical microscopy (s-SNOM) and low-ener...
Antiferromagnetic Potts model on the Erdos-Renyi random graph
Mean field dilute antiferromagnet q-state Potts model interpolation extended variational principle
2011/7/28
Abstract: We study the antiferromagnetic Potts model on the Erdos-Renyi random graph. By identifying a suitable interpolation structure and proving an extended variational principle we show that the r...
