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…
Collective modes and gapped momentum states in liquid Ga: experiment, theory and simulation
Ramil M. Khusnutdinoff, Cillian Cockrell, Oliver A. Dicks +7
Collective excitations in liquids are important for understanding liquid dynamical and thermodynamic properties. Gapped momentum states (GMS) are a notable feature of liquid dynami…
Experimental and modelling evidence for structural crossover in supercritical CO
Cillian J. Cockrell, Oliver Dicks, Ling Wang +4
Physics of supercritical state is understood to a much lesser degree compared to subcritical liquids. Carbon dioxide in particular has been intensely studied, yet little is known a…
Existence of a Spectral Gap in the Affleck-Kennedy-Lieb-Tasaki Model on the Hexagonal Lattice
Marius Lemm, Anders W. Sandvik, Ling Wang
The Affleck-Kennedy-Lieb-Tasaki (AKLT) quantum spin chain was the first rigorous example of an isotropic spin system in the Haldane phase. The conjecture that the AKL…
