QUANTUM PHASE TRANSITIONS AND TOPOLOGICAL ORDERS IN SPIN CHAINS AND LADDERS
Dimerized antiferromagnetic spin-1/2 chains and ladders demonstrate quantum critical phase transition, the existence or absence of which is dependent on the dimerization and the dimerization pattern of the chain and the ladder, respectively. The gapped phases can not be distinguished by the conventi...
