Estimation of the cumulant and sextic self-coupling of the QCD axion at finite temperature and density
Xinguang Li, Zhao Zhang
The sixth-order cumulant of the QCD topological charge distribution and the axion's sextic self-coupling at finite temperature and baryon chemical potential are calcu…

Controlling the Symmetry Breaking Threshold in Bipartite Lattice Systems with Floquet Topological Edge States
Xinguang Li, Hongzheng Wu, Yangchun Zhao +5
We investigate the control of the parity-time ()-symmetry breaking threshold in a periodically driven one-dimensional dimerized lattice with spatially symmetric gain…

Generation and Stabilization of Bound States in the Continuum in Dissipative Floquet Optical Lattices
Yangchun Zhao, Hongzheng Wu, Xinguang Li +5
This paper investigates the generation and stabilization of bound states in the continuum (BICs) in a one-dimensional dissipative Floquet lattice. We find a different mechanism for…
