Highly Entangled Quantum Spin Chains on Fermat's Spiral
Zhao Zhang, Olai B. Mykland
We investigate the entanglement entropy (EE) and spectral gap properties of highly entangled spin chains arranged along a Hamiltonian path on a two-dimensional (2D) lattice with ge…

Highly Entangled 2D Ground States: Tensor Network, Order Parameter and Correlation
Olai B. Mykland, Zhao Zhang
In this article we present analytical results on the exact tensor network representations and correlation functions of the first examples of 2D ground states with quantum phase tra…
