A novel nonlinear spin wave theory for the spin 1/2 antiferromagnetic Heisenberg model on a triangular lattice
Lihua Wang, Sung Gong Chung
We extend the nonlinear spin wave theory (NLSWT) for the spin 1/2 antiferromagnetic Heisenberg model on a triangular lattice (TAFHM). This novel NLSWT considers the corrections one…

Entanglement Perturbation Theory for Antiferromagnetic Heisenberg Spin Chains
Lihua Wang, Sung Gong Chung
A recently developed numerical method, entanglement perturbation theory (EPT), is used to study the antiferromagnetic Heisenberg spin chains with z-axis anisotropy and magnetic…

Entanglement Perturbation Theory for Infinite Quasi-1D Quantum Systems
Lihua Wang, Sung Gong Chung
We develop Entanglement Perturbation Theory (EPT) for infinite Quasi-1D quantum systems. The spin 1/2 Heisenberg chain with ferromagnetic nearest neighbor (NN) and antiferromagneti…
