Critical Lines and Massive Phases in Quantum Spin Ladders with Dimerization

Javier Almeida, M. A. Martin-Delgado, G. Sierra

We determine the existence of critical lines in dimerized quantum spin ladders in their phase diagram of coupling constants using the finite-size DMRG algorithm. We consider both s…
