Nearly deconfined spinon excitations in the square-lattice spin-1/2 Heisenberg antiferromagnet
Hui Shao, Yan Qi Qin, Sylvain Capponi +3
We study the dynamic spin structure factor of the spin- square-lattice Heisenberg antiferromagnet and of the - model (with 4-spin interactions and Heisenberg exchang…
Unifying static and dynamic properties in 3D quantum antiferromagnets
H. D. Scammell, Y. Kharkov, Yan Qi Qin +3
Quantum Monte Carlo simulations offer an unbiased means to study the static and dynamic properties of quantum critical systems, while quantum field theory provides direct analytica…
Duality between the deconfined quantum-critical point and the bosonic topological transition
Yan Qi Qin, Yuan-Yao He, Yi-Zhuang You +5
Recently significant progress has been made in -dimensional conformal field theories without supersymmetry. In particular, it was realized that different Lagrangians may be…
The amplitude mode in three-dimensional dimerized antiferromagnets
Yan Qi Qin, Bruce Normand, Anders Sandvik +1
The amplitude (Higgs) mode is a ubiquitous collective excitation related to spontaneous breaking of a continuous symmetry. We combine quantum Monte Carlo (QMC) simulations with sto…
Multiplicative logarithmic corrections to quantum criticality in three-dimensional dimerized antiferromagnets
Yan Qi Qin, Bruce Normand, Anders W. Sandvik +1
We investigate the quantum phase transition in an dimerized Heisenberg antiferromagnet in three spatial dimensions. By performing large-scale quantum Monte Carlo simulati…
