Frustrated Rydberg Atom Arrays Meet Cavity-QED: Emergence of the Superradiant Clock Phase
Ying Liang, Bao-Yun Dong, Zi-Jian Xiong +1
Rydberg atom triangular arrays in an optical cavity serve as an ideal platform for understanding the interplay between geometric frustration and quantized photons. Using a large-sc…
Universal critical dynamics of quantum geometry
Shuohang Wu, Zhengxin Guo, Zijian Xiong +2
In this study, we prove that the quantum critical point in the ground state of quantum many-body systems, can also govern the universal dynamical behavior when the systems are driv…
Level spacing statistics of two unitary equivalent models with distinct local symmetries
Biquan Yang, Zijian Xiong
The full spectrum and integrability of unitary equivalent models are the same. A standard diagnostic tool of integrability is level spacing statistics which requires separating the…
1-form symmetry and the selection rule of the plaquette valence bond solid phase on kagome lattice
Zijian Xiong
We study the plaquette valence bond solid phase in a XXZ type spin-1/2 model in the kagome lattice. The low energy theory for this phase is a U(1) lattice gauge theory on the honey…

Zijian Xiong
We study the low energy effective theory of spin-1/2 quantum ice on the planar pyrochlore lattice from the perspective of its global symmetries. We show that the Fourier transform…
Deconfined quantum phase transition on the kagome lattice: Distinct velocities of spinon and string excitations
Dong-Xu Liu, Zijian Xiong, Yining Xu +1
Deconfined quantum phase transition (DQPT) provides an extraordinary possibility of the quantum phase transition beyond the Ginzburg-Landau paradigm, which is interwoven with numer…
Evidence for distortion-induced local electric polarization in -RuCl
Xinrun Mi, De Hou, Xiao Wang +14
The spin-orbit assisted Mott insulator -RuCl is a prime candidate for material realization of the Kitaev quantum spin liquid. While little attention has been paid to charge…
Persistent Corner Spin Mode at the Quantum Critical Point of a Plaquette Heisenberg Model
Yining Xu, Chen Peng, Zijian Xiong +1
Gapless edge states are the hallmark of a large class of topological states of matter. Recently, intensive research has been devoted to understanding the physical properties of the…
Dynamics in the planar pyrochlore lattice: bow-tie flat band and mixed 't Hooft anomaly
Zijian Xiong, Yining Xu, Xue-Feng Zhang
The quantum phase transition between plaquette valence bound solid (PVBS) and superfluid (SF) phases on the planar pyrochlore lattice (square ice) is under debate,…
Fractional and composite excitations of antiferromagnetic quantum spin trimer chains
Jun-Qing Cheng, Jun Li, Zijian Xiong +3
Using quantum Monte Carlo, exact diagonalization and perturbation theory, we study the spectrum of the antiferromagnetic Heisenberg trimer chain by varying the ratio $g=J_2…
Resonant inelastic x-ray scattering study of vector chiral ordered kagome antiferromagnet
Zijian Xiong, Trinanjan Datta, Dao-Xin Yao
We study the resonant inelastic x-ray scattering (RIXS) features of vector chiral ordered kagome antiferromagnets. Utilizing a group theoretical formalism that respects lattice sit…
Nonanalyticity of circuit complexity across topological phase transitions
Zijian Xiong, Dao-Xin Yao, Zhongbo Yan
The presence of nonanalyticity in observables is a manifestation of phase transitions. Through the study of two paradigmatic topological models in one and two dimensions, in this w…
