Phase Diagram of the Easy-Axis Triangular-Lattice J<sub>1</sub>-J<sub>2</sub> Model
ORAL
Abstract
The phase diagram of the S=1/2 easy-axis triangular-lattice J1-J2 model is investigated using density-matrix renormalization group and analytical insights. We find a significant spin-liquid region extending from the Heisenberg limit and residing between the Y phase-known as the magnetic analogue of the supersolid-and collinear stripe phase. The order parameters of the supersolid are analyzed and an understanding of the lack of ferromagnetic moment in it is suggested.
