摘要：
By using semiclassical theory combined with multiple-scale method, we analytically study the linear absorption and the nonlinear dynamical properties in a lifetime broadened Λ-type three-level self-assembled quantum dots. It is found that this system can exhibit the transparency, and the width of the transparency window becomes wider with the increase of control light field. Interestingly, a weak probe light beam can form spatial weak-light dark solitons. When it propagates along the axial direction, the soliton will transform into a steady spatial weak-light ring dark soltion. In addition, the stability of two-dimensional spatial optical solitons is testified numerically.

摘要：
We address the impact of imprinted fading optical lattices on the beam evolution of solitons in strongly nonlocal nonlinear media. The results show that the width of the soliton experiences a change with the increasing propagation distance, the critical power for the soliton varies with the lattice fading away, and the soliton breathing is affected by the initial lattice depth and the nonlocality degree.

摘要：
基于Dini级数展开, 导出了p(>0)阶准离散Hankel变换(the pth-order quasi-discrete Hankel transform based on Dini series expansion, pDQDHT)算法, 并给出了该算法在光束传输中的应用. 通过不同输入函数分别对pDQDHT算法进行测试及光束通过透镜传输的应用实例, 结果表明: pDQDHT算法不仅精度高于现有的Hankel变换算法, 可以进行多次正、逆变换, 能广泛应用于光束分步传输问题, 而且执行速度也与一般的快速Hankel变换算法相当.

摘要：
We study the soliton mobility in nonlocal nonlinear media with an imprinted fading optical lattice. The results show that the transverse mobility of solitons varies with the lattice decay rate and the nonlocality degree, which provides an opportunity for all-optical control of light.

摘要：
A scheme is presented for generating four-photon Greenberger-Hornc-Zeilinger(GHZ) states with resonant interaction between a cascade type three-level atom and two bimodal cavities.In the proposed protocol,the quantuni information is encoded on Fock states of the cavity fields.Schrodinger equation of the system is solved and quantum states of interaction system are obtained.The detection of atom can collapse cavity to the desired GHZ state.It is shown that the scheme is simple and the experimental implementation is feasible.

摘要：
A simple scheme is presented for generating 2n-mode photon Greenberger-Horne-Zeilinger (GHZ) states with the interaction of a 2n-level atom with two n-mode cavities.In the proposed protocol, the 2n qubits are encoded in zero-and one-photon Fock states of 2n cavity modes.Because the interaction between the atom and cavity fields is resonant,the coupling strength can be relative strong.This will shorten the corresponding interaction time and thus reduce the effect of decoherence in experiment.
