Two Plaquette-Singlet Phases and Emergent SO(5) Deconfined Quantum Criticality in SrCu2(BO3)2
Yi Cui, Kefan Du, Zhanlong Wu +15
The deconfined quantum critical point (DQCP) has become a central open concept in the physics of quantum matter, and its proposed presence in the Shastry-Sutherland model was follo…
Thermal Tensor Network Approach for Spin-Lattice Relaxation in Quantum Magnets
Ning Xi, Yuan Gao, Chengchen Li +4
Low-dimensional quantum magnets, particularly those with strong spin frustration, are characterized by their notable spin fluctuations. Nuclear magnetic resonance (NMR) serves as a…
Quantum scaling of the spin lattice relaxation rate in the checkerboard - model
Chengchen Li, Huihang Lin, Rong Yu
Motivated by recent progress on the experimental realization of proximate deconfined quantum critical point in a frustrated quantum magnet, we study the low-energy spin dynamics of…
Semiclassical approach to spin dynamics of a ferromagnetic S=1 chain
Chengchen Li, Yi Cui, Weiqiang Yu +1
Motivated by recent experimental progress in the quasi-one-dimensional quantum magnet NiNbO, we study the spin dynamics of an S=1 ferromagnetic Heisenberg chain with single…
