Emergent criticality in fully frustrated quantum magnets
Yuchen Fan, Ning Xi, Changle Liu +2
Phase transitions in condensed matter are often linked to exotic emergent properties. We study the fully frustrated bilayer Heisenberg antiferromagnet to demonstrate that an applie…
Nature of the 1/9-magnetization plateau in the spin-1/2 kagome Heisenberg antiferromagnet
Da-zhi Fang, Ning Xi, Shi-Ju Ran +1
The nature of the 1/9-magnetization plateau of the spin-1/2 kagome Heisenberg antiferromagnet remains controversial due to the exotic physical properties and high complexity induce…
Plaquette Singlet Transition, Magnetic Barocaloric Effect, and Spin Supersolidity in the Shastry-Sutherland Model
Junsen Wang, Han Li, Ning Xi +4
Inspired by recent experimental measurements [Guo \textit{et al.}, Phys. Rev. Lett.~\textbf{124}, 206602 (2020); Jiménez \textit{et al.}, Nature \textbf{592}, 370 (2021)] on frustr…
Dipolar Spin Liquid Ending with Quantum Critical Point in a Gd-based Triangular Magnet
Junsen Xiang, Cheng Su, Ning Xi +12
By performing experiment and model studies on a triangular-lattice dipolar magnet KBaGd(BO) (KBGB), we find the highly frustrated magnet with a planar anisotropy hosts a st…
Proximate deconfined quantum critical point in SrCu2(BO3)2
Yi Cui, Lu Liu, Huihang Lin +10
The deconfined quantum critical point (DQCP) represents a paradigm shift in quantum matter studies, presenting a "beyond Landau" scenario for order--order transitions. Its experime…
Dynamical signatures of the one-dimensional deconfined quantum critical point
Ning Xi, Rong Yu
We study the critical scaling and dynamical signatures of fractionalized excitations at two different deconfined quantum critical points (DQCPs) in an spin chain by using…
Emergent O(4) symmetry at an one-dimensional deconfined quantum tricritical point
Ning Xi, Rong Yu
We show an symmetry emerges at a deconfined quantum tricritical point of a valence bond solid and two ferromagnetic phases in an frustrated spin chain by combi…
First-order transition between the plaquette valence bond solid and antiferromagnetic phases of the Shastry-Sutherland model
Ning Xi, Hongyu Chen, Z. Y. Xie +1
We study the ground state phase diagram of the Shastry-Sutherland model by using the variational optimization of the infinite tensor network states, and find a weakly first-order t…
Quantum criticality of the Ising-like screw chain antiferromagnet SrCo2V2O8 in a transverse magnetic field
Y. Cui, H. Zou, N. Xi +9
The quantum criticality of an Ising-like screw chain antiferromagnet SrCoVO, with a transverse magnetic field applied along the crystalline -axis, is investigated by…
