Dynamical properties of quantum many-body systems with long range interactions
Menghan Song, Jiarui Zhao, Chengkang Zhou +1
Employing large-scale quantum Monte Carlo simulations, we systematically compute the energy spectra of the 2D spin-1/2 Heisenberg model with long-range interactions. With the $1/r^…
Detecting Subsystem Symmetry Protected Topological Order Through Strange Correlators
Chengkang Zhou, Meng-Yuan Li, Zheng Yan +2
We employ strange correlators to detect 2D subsystem symmetry-protected topological (SSPT) phases which are nontrivial topological phases protected by subsystem symmetries. Specifi…
Evolution of Dynamical Signature in the X-cube Fracton Topological Order
Chengkang Zhou, Meng-Yuan Li, Zheng Yan +2
As an unconventional realization of topological orders with an exotic interplay of topology and geometry, fracton (topological) orders feature subextensive topological ground state…
Amplitude Mode in Quantum Magnets via Dimensional Crossover
Chengkang Zhou, Zheng Yan, Han-Qing Wu +3
We investigate the amplitude (Higgs) mode associated with longitudinal fluctuations of the order parameter at the continuous spontaneous symmetry breaking phase transition. In quan…
Klein tunneling of Weyl magnons
Chengkang Zhou, Luyang Wang, Dao-Xin Yao
Similar to Weyl semimetals, in magnetic materials, magnon bands can host Weyl points, around which the bosonic excitations are called Weyl magnons. Here, we investigate the Klein t…
XXZ-Ising model on the triangular kagome lattice with spin-1 on the decorated trimers
Chengkang Zhou, Yuanwei Feng, Jiawei Ruan +1
We consider the triangular kagome XXZ-Ising model (TKL XXZ-Ising model) formed by inserting small triangles ("a-trimers") with XXZ spin-1 inside the triangles of the kagome lattice…
Noncommutative Scalar Solitons at Finite
Chen-Gang Zhou
We investigate the behavior of the noncommutative scalar soliton solutions at finite noncommutative scale . A detailed analysis of the equation of the motion indicates that fewe…
