Dynamical evolution of an effective two-level system with PT symmetry
Lei Du, Zhihao Xu, Chuanhao Yin +1
We investigate the dynamics of parity- and time-reversal (PT ) symmetric two-energy-level atoms in the presence of two optical and a radio-frequency (rf) fields. The strength and r…

Dynamical evolutions in non-Hermitian triple-well system with complex potential
Liping Guo, Lei Du, Chuanhao Yin +2
We investigate the dynamical properties for non-Hermitian triple-well system with a loss in the middle well. When chemical potentials in two end wells are uniform and nonlinear int…

-flux loop semimetals
Linhu Li, Stefano Chesi, Chuanhao Yin +1
We introduce a model of -flux loop semimetals which holds nodal loops described by a winding number . By adding some extra terms, this model can be transformed into a rece…
