    "abstract": "We investigate quantum phase transitions in ladders of spin 1/2 particles by\nengineering suitable matrix product states for these ladders. We take into\naccount both discrete and continuous symmetries and provide general classes of\nsuch models. We also study the behavior of entanglement of different\nneighboring sites near the transition point and show that quantum phase\ntransitions in these systems are accompanied by divergences in derivatives of\nentanglement.",
