Can a spin chain relate combinatorics to number theory?
Kun Hao, Olof Salberger, Vladimir Korepin
The Motzkin spin chain is a spin- frustration-free model introduced by Shor & Movassagh. The ground state is constructed by mapping random walks on the upper half of the square…

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…

Fredkin Spin Chain
Olof Salberger, Vladimir Korepin
We introduce a new model of interacting spin 1/2. It describes interaction of three nearest neighbors. The Hamiltonian can be expressed in terms of Fredkin gates. The Fredkin gate…
