Field-Induced Ising Criticality and Incommensurability in Anisotropic Spin-1 Chains
Y. -J. Wang
Quantum phase transitions induced by an external magnetic field in the Haldane-gapped spin-1 chains are studied in a fermionic field-theoretic description of the model. In the case…

Phase diagrams of the generalized spin-1/2 ladder under staggered field and dimerization: A renormalization group study
Y. -J. Wang
In the weak-coupling regime of the continuous theories, two sets of one-loop renormalization group equations are derived and solved to disclose the phase diagrams of the antiferrom…
