| Title: | Quantum phase transition on a spin-one spatially anisotropic frustrated zigzag square lattice |
| Authors: | Antônio Sérgio Teixeira Pires |
| Abstract: | We study quantum phase transitions in the easy-plane spin-one Heisenberg model on a zigzag square lattice with next-nearest-neighbor interactions at zero temperature using the SU(3) Schwinger boson formalism in a mean field approximation. We present the phase diagram and the dispersion relation for several values of the parameters. A magnetically disordered region in the phase diagram is found, even when the anisotropy parameter vanishes. |
