Long-range spin correlations in a honeycomb spin model with magnetic field
A. V. Lunkin, K. S. Tikhonov, M. V. Feigel'man
We consider spin- model on the honeycomb lattice in the presence of weak magnetic field . Such a perturbation treated in the second order over leads to the…

Power-law spin correlations in a perturbed honeycomb spin model
Kostantin S. Tikhonov, Mikhail V. Feigel'man, Alexei Yu. Kitaev
We consider spin- model on the honeycomb lattice~\cite{Kitaev06} in presence of a weak magnetic field . Such a perturbation destroys exact integrability of…
