Single-layer framework of variational tensor network states
Hongyu Chen, Yangfeng Fu, Weiqiang Yu +2
We propose a single-layer tensor network framework for the variational determination of ground states in two-dimensional quantum lattice models. By combining the nested tensor netw…

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…

Spin excitations of the Shastry-Sutherland model -- altermagnetism and deconfined quantum criticality
Hongyu Chen, Guijing Duan, Changle Liu +4
Frustrated quantum magnets can host a variety of exotic spin excitations, including fractionalized spin excitations coupled to emergent gauge fields at deconfined quantum critical…
