Non-Interacting Motzkin Chain - Periodic Boundary Conditions
Olof Salberger, Pramod Padmanabhan, Vladimir Korepin
The Motzkin spin chain is a spin-1 model introduced in \cite{shor} as an example of a system exhibiting a high degree of quantum fluctuations whose ground state can be mapped to Mo…

Quantum Phase Transitions and Localization in Semigroup Fredkin Spin Chain
Pramod Padmanabhan, Fumihiko Sugino, Vladimir Korepin
We construct an extended quantum spin chain model by introducing new degrees of freedom to the Fredkin spin chain. The new degrees of freedom called arrow indices are partly associ…
