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…
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,…
Spin excitation spectra of the two dimensional Heisenberg model with a checkerboard structure
Yining Xu, Zijian Xiong, Han-Qing Wu +1
We study the spin excitation spectra of the two-dimensional spin- Heisenberg model with a checkerboard structures using stochastic analytic continuation of the imaginary-time…
