Gapless and Massive 1D Singlet Dispersion Channel in Infinite Spin-1/2 Ladders ---Infinite Quasi-1D Entanglement Perturbation Theory for Excitation
Lihua Wang, Aslam Parvej, D. ChangMo Yang +1
We solve for the elementary excitation in infinite quasi-1D quantum lattices by extending the recently developed infinite quasi-1D entanglement perturbation theory. The wave functi…
Supra-Binary Ferroelectricity in a Nanowire
Wentao Xu, Lihua Wang, Yeongjun Lee +5
We report the prediction and observation of supra-binary ferroelectricity in a ferroelectric nanowire (FNW) covered with a semi-cylindrical gate that provides an anisotropic electr…
Space Reduction in Matrix Product State
Lihua Wang, Kwang S. Kim
We reconstruct a matrix product state (MPS) in reduced spaces using density matrix. This scheme applies to a MPS built on a blocked quantum lattice. Each block contains physica…
Quantum Dimensional Transition in Spin- Antiferromagnetic Heisenberg Model on A Square Lattice and Space Reduction in Matrix Product State
Lihua Wang, Kwang S. Kim
We study the spin- antiferromagnetic Heisenberg model on an infinity-by- square lattice for even 's up to . Previously, the nonlinear sigma model perturbativ…
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…
Entanglement perturbation theory for the elementary excitation in one dimension
Sung Gong Chung, Lihua Wang
The entanglement perturbation theory is developed to calculate the excitation spectrum in one dimension. Applied to the spin- antiferromagnetic Heisenberg model, it re…
