Infinite number of solvable generalizations of XY-chain, with cluster state, and with central charge c=m/2
An infinite number of spin chains are solved and it is derived that the ground-state phase transitions belong to the universality classes with central charge c=m/2, where m is an integer. The models are diagonalized by automatically obtained transformations, many of which are different from the Jord...
