Dynamics and correlations in Motzkin and Fredkin spin chains
L. Dell'Anna, L. Barbiero, A. Trombettoni
The Motzkin and Fredkin quantum spin chains are described by frustration-free Hamiltonians recently introduced and studied because of their anomalous behaviors in the correlation f…

Haldane Topological Orders in Motzkin Spin Chains
L. Barbiero, L. Dell'Anna, A. Trombettoni +1
Motzkin spin chains are frustration-free models whose ground-state is a combination of Motzkin paths. The weight of such path contributions can be controlled by a deformation param…

Spreading of correlations in a quenched repulsive and attractive one dimensional lattice system
L. Barbiero, L. Dell'Anna
We study the real time evolution of the correlation functions in a globally quenched interacting one dimensional lattice system by means of time adaptive density matrix renormaliza…
