Investigation of Quantum Phase Transitions using Multi-target DMRG Methods
C. Degli Esposti Boschi, F. Ortolani
In this paper we examine how the predictions of conformal invariance can be widely exploited to overcome the difficulties of the density-matrix renormalization group near quantum c…

Low-Dimensional Spin Systems: Hidden Symmetries, Conformal Field Theories and Numerical Checks
C. Degli Esposti Boschi, E. Ercolessi, G. Morandi
We review here some general properties of antiferromagnetic Heisenberg spin chains, emphasizing and discussing the role of hidden symmetries in the classification of the various ph…
