Joint remote state preparation is a multiparty global quantum task in which several parties are assigned to jointly prepare a quantum state for a remote party. Although various protocols have been proposed so far, none of them are absolutely secure in ... see more

The Vicsek’s model (VM) [T. Vicsek, et. al., Phys. Rev. Lett. 75, 1226 (1995)] is apopular approach to study nature of the phase transition of self-propelling system. In this model,the direction of motion of each particle depends on the average velocity o... see more

The influence of the self-focusing effect arised from Kerr effect on the optical force acting on the dielecric particle embedded in the Kerr medium, which is irradiated by the Gaussian beam, is proposed to concern. The expressions of the optical forces wi... see more

In the framework of the semiclassical theory, we develop an analytical approach on electromagnetically induced transparency (EIT) in the medium consists of five-level cascade scheme of cold 85Rb atoms. In the weak field limit of the probe light, an analyt... see more

We consider a model of a passively mode-locking fiber ring laser bult using a saturable absorber and a chirped fiber Bragg grating to balance dispersion and nonlinearity. The evolution of the slowly envelope of the optical field in a loop fiber subject to... see more

It has been observed that at the large time scales the distributionof stock market returns is convergent from Boltzmann distribution to Gaussianasymptotic one. To explain this universal phenomenon, we propose a new andsimple dynamic model to describe this... see more
