Holographic rainbow networks for colorful Motzkin and Fredkin spin chains
Rafael N. Alexander, Amr Ahmadain, Zhao Zhang +1
We present bulk tensor networks that exactly represent the ground states of a continuous family of one-dimensional frustration-free Hamiltonians. These states, which are known as a…

Quantum phase transition from bounded to extensive entanglement entropy in a frustration-free spin chain
Zhao Zhang, Amr Ahmadain, Israel Klich
We introduce a continuous family of frustration-free Hamiltonians with exactly solvable ground states. We prove that the {ground state of our model is non-degenerate and exhibits}…
