Majorana-like oscillation for edge states in one-dimensional topological chain with dissipative couplings
Yang Zhang, Wei Nie, Yu-xi Liu
The oscillation of Majorana modes with near zero energy plays a very important role for ascertaining Majorana fermions. The edge states, which also have almost-zero-energy in one-d…
Optical properties of a waveguide-mediated chain of randomly positioned atoms
Guo-Zhu Song, Jin-Liang Guo, Wei Nie +2
We theoretically study the optical properties of an ensemble of two-level atoms coupled to a one-dimensional waveguide. In our model, the atoms are randomly located in the lattice…
Bandgap-Assisted Quantum Control of Topological Edge States in a Cavity
Wei Nie, Yu-xi Liu
Quantum matter with exotic topological order has potential applications in quantum computation. However, in present experiments, the manipulations on topological states are still c…
Superposition of macroscopically squeezed states with enhanced squeezing in cavity optomechanical system at single-photon level
Sai-Nan Huai, Wei Nie, Yun-bo Zhang +1
We propose an efficient approach to generate the superposed macroscopically squeezed states with enhanced squeezing in a two-mode optomechanical system. This can be achieved by int…
Topologically Protected Quantum Coherence in a Superatom
Wei Nie, Z. H. Peng, Franco Nori +1
Exploring the properties and applications of topological quantum states is essential to better understand topological matter. Here, we theoretically study a quasi-one-dimensional t…
Photon transport mediated by an atomic chain trapped along a photonic crystal waveguide
Guo-Zhu Song, Ewan Munro, Wei Nie +3
We theoretically investigate the transport properties of a weak coherent input field scattered by an ensemble of -type atoms coupled to a one-dimensional photonic crystal wavegu…
