Valence-bond crystal in the extended Kagomé spin-1/2 quantum Heisenberg antiferromagnet: A variational Monte Carlo approach
Valence-bond crystal extended Kagomé spin-1/2 quantum variational Monte Carlo approach
2010/11/24
The highly-frustrated spin-1=2 quantum Heisenberg model with both nearest (J1) and next-
nearest (J2) neighbor exchange interactions is revisited by using an extended variational space
of projected ...
Phase Structure of Anisotropic Antiferromagnetic Heisenberg Model on Layered Triangular Lattice: Spiral State and Deconfined Spin Liquid
Phase Structure Deconfined Spin Liquid

In the present paper, we study spin- 1 2 antiferromagnetic (AF) Heisenberg model on layered anisotropic triangular lattice and obtain its phase structure. We use the Schwinger bosons for representing ...
