Quantum Phase Transitions and Matrix Product States in Spin Ladders

Phys. Rev. B 75, 224427 (2007) We investigate quantum phase transitions in ladders of spin 1/2 particles by engineering suitable matrix product states for these ladders. We take into account both discrete and continuous symmetries and provide general classes of such models. We also study the behavio...
