Charge Density Distributions in Doped Antiferromagnetic Insulators
arXiv:cond-mat/0302253 · doi:10.1103/PhysRevB.69.012401
Abstract
We consider the form of the charge density nano-scale configurations in underdoped states of planar antiferromagnetic insulators in the framework of a soft variant of Faddeev-Niemi model. It is shown that there is such a level of doping and the temperature range, where charge density distributions in the form of closed quasi-one-dimensional structures are more preferable.
