Exact critical exponents of the Motzkin and Fredkin Chains
Olai B. Mykland, Zhao Zhang
The Motzkin and Fredkin chains are frustration-free spin models with exactly solvable ground states whose -deformations realize an exotic quantum phase transition from a disorde…
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…
Resonating Valence Bond Ground States on Corner-sharing Simplices
Zhao Zhang, Cecilie Glittum
The Hubbard model in the limit has been known to have resonating valence bond (RVB) ground states on certain corner-sharing simplex lattices. Examples include both the…
Bootstrapping the -matrix
Zhao Zhang
A bootstrap program is presented for algebraically solving the -matrix of a generic integrable quantum spin chain from its Hamiltonian. The Yang-Baxter equation contains an infi…
One-Shot Simulation of Static Disorder in Quantum Dynamics with Equilibrium Initial State via Matrix Product State Sampling
Zhao Zhang, Jiajun Ren, Wei-Hai Fang
Static disorder plays a crucial role in the electronic dynamics and spectroscopy of complex molecular systems. Traditionally, obtaining observables averaged over static disorder re…
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…
