Locally tunable disorder and entanglement in the one-dimensional plaquette orbital model

We introduce a one-dimensional plaquette orbital model with a topology of a ladder and alternating interactions between x and z pseudospin components both along the ladder legs and on the rungs. We show by an exact transformation that it is equivalent to an effective spin model in a magnetic field,...
