Next-nearest-neighbor spin-spin and chiral-spin correlation functions in generalized XXX chain
V. V. Mkhitaryan, A. G. Sedrakyan
We develop a simple technique for calculation of next to nearest neighbor spin-spin and chiral-spin correlation functions in inhomogeneous XXX model. Exact expression of the chiral…

Mean-field theory for Heisenberg zigzag ladder: Ground state energy and spontaneous symmetry breaking
V. V. Mkhitaryan, T. A. Sedrakyan
The spin-1/2 zig-zag Heisenberg ladder (J_1 - J_2 model) is considered. A new representation for the model is found and a saddle point approximation over the spin-liquid order para…
