Tensor Product State Formulation for the Spin 1/2 Antiferromagnetic XXZ Model on the Checkerboard Lattice
Nobuya Maeshima
Vertical density matrix algorithm (VDMA), a tensor product state formulation of the ``higher-dimensional'' density matrix renormalization group, is applied to the spin 1/2 antiferr…

Frustration-induced eta inversion in the S=1/2 bond-alternating spin chain
Nobuya Maeshima, Kouichi Okunishi, Kiyomi Okamoto +1
We study the frustration-induced enhancement of the incommensurate correlation for a bond-alternating quantum spin chain in a magnetic field, which is associated with a quasi-one-d…

Tensor Product Variational Formulation for Quantum Systems
Y. Nishio, N. Maeshima, A. Gendiar +1
We consider a variational problem for the two-dimensional (2D) Heisenberg and XY models, using a trial state which is constructed as a 2D product of local weights. Variational ener…
