The origin of hour-glass magnetic dispersion in underdoped cuprate superconductors
Y. A. Kharkov, O. P. Sushkov
In the present work we explain the hour-glass magnetic dispersion in underdoped cuprates. The dispersion arises due to the Lifshitz-type magnetic criticality. Superconductivity als…

Bound states of skyrmions and merons near the Lifshitz point
Y. A. Kharkov, O. P. Sushkov, M. Mostovoy
We study topological defects in anisotropic ferromagnets with competing interactions near the Lifshitz point. We show that skyrmions and bi-merons are stable in a large part of the…
