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…
Geometrical meaning of winding number and its characterization of topological phases in one-dimensional chiral non-Hermitian systems
Chuanhao Yin, Hui Jiang, Linhu Li +2
We unveil the geometrical meaning of winding number and utilize it to characterize the topological phases in one-dimensional chiral non-Hermitian systems. While chiral symmetry ens…
Transition from nodal loop to nodal chain phase in a periodically modulated optical lattice
Chuanhao Yin, Linhu Li, Shu Chen
We propose to study the transition from a nodal loop to nodal chain phase in a tunable two-dimensional -flux lattice with periodical modulation potential. The Hamiltonian descri…
-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…
Chiral topological insulating phases from three-dimensional nodal loop semimetals
Linhu Li, Chuanhao Yin, Shu Chen +1
We identify a topological Z index for three dimensional chiral insulators with P*T symmetry where two Hamiltonian terms define a nodal loop. Such systems may belong in the AIII or…
Topologically nontrivial states in one-dimensional nonlinear bichromatic superlattices
C. S. Liu, Z. Z. Wang. Chuanhao Yin, Y. D. Wu +3
We study topological properties of one-dimensional nonlinear bichromatic superlattices and unveil the effect of nonlinearity on topological states. We find the existence of nontriv…
Dynamical Anderson transition in one-dimensional periodically kicked incommensurate lattices
Pinquan Qin, Chuanhao Yin, Shu Chen
We study the dynamical localization transition in a one-dimensional periodically kicked incommensurate lattice, which is created by perturbing a primary optical lattice periodicall…
