Bose-Einstein condensation of a two-magnon bound state in a spin-one triangular lattice
Jieming Sheng, Jia-Wei Mei, Le Wang +31
In ordered magnets, the elementary excitations are spin waves (magnons), which obey Bose-Einstein statistics. Similarly to Cooper pairs in superconductors, magnons can be paired in…
Quantum spin liquid phase in the Shastry-Sutherland model detected by an improved level spectroscopic method
Ling Wang, Yalei Zhang, Anders W. Sandvik
We study the spin- two-dimensional Shastry-Sutherland spin model by exact diagonalization of clusters with periodic boundary conditions. We develop an improved level spectrosc…
Quantum Criticality and Spin Liquid Phase in the Shastry-Sutherland model
Jianwei Yang, Anders W. Sandvik, Ling Wang
Using the density-matrix renormalization group method for the ground state and excitations of the Shastry- Sutherland spin model, we demonstrate the existence of a narrow quantum s…
Quantum phases of SrCu2(BO3)2 from high-pressure thermodynamics
Jing Guo, Guangyu Sun, Bowen Zhao +9
We report heat capacity measurements of SrCu(BO) under high pressure along with simulations of relevant quantum spin models and map out the phase diagram of the…
Dynamic structure factor from real time evolution and exact correction vectors with matrix product states
Ling Wang, Hai-Qing Lin
We propose two complimentary numerical methods for rigorous computation of dynamic structure factor at zero temperature. One solution is to solve Schrodinger equation using time de…
Critical level crossings and gapless spin liquid in the square-lattice spin- - Heisenberg antiferromagnet
Ling Wang, Anders W. Sandvik
We use the DMRG method to calculate several energy eigenvalues of the frustrated square-lattice - Heisenberg model on cylinders with . We…
