Hierarchical mean-field approach to the $J_{1}$ - $J_{2}$ Heisenberg model on a square lattice

L. Isaev, G. Ortiz, J. Dukelsky

We study the quantum phase diagram and excitation spectrum of the frustrated $J_{1}$ - $J_{2}$ spin-1/2 Heisenberg Hamiltonian. A hierarchical mean-field approach, at the heart of which…

Structures of Order Parameters in Inhomogeneous Phase States of Strongly Correlated Systems

L. S. Isaev, A. P. Protogenov

The structures of order parameters which determine the bounds of the phase states in the framework of the $C P^{1}$ Ginzburg-Landau model were considered. Using the formulation of t…

Charge Density Distributions in Doped Antiferromagnetic Insulators

L. S. Isaev, A. P. Protogenov

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…
