Abstract:Cluster synchronization of complex dynamical networks with fractional-order dynamical nodes is discussed in the paper. By using the stability theory of fractional-order differential system and linear pinning control, a sufficient condition for the stability of the synchronization behavior in complex networks with fractional order dynamics is derived. Only the nodes in one community which have direct connections to the nodes in other communities are needed to be controlled, resulting in reduced control cost. A numerical example is presented to demonstrate the validity and feasibility of the obtained result. Numerical simulations illustrate that cluster synchronization performance for fractional-order complex dynamical networks is influenced by inner-coupling matrix, control gain, coupling strength and topological structures of the networks. | |||

Abstract:Fast-response photoelectric effect has been observed in the as-supplied sapphire single crystals without any bias at ambient temperature under irradiation of a 1064 nm pulsed laser of 25 ps in duration. The rise time and full width at half maximum are about 0.8 ns and 0.42 ns for 0o tilting sample, 0.8 ns and 0.64 ns for 10o tilting sample. The peak values increased nearly linearly with the on-sample energy density. The possible mechanism can be described as the combination of the laser-induced hot carrier photovoltaic effect and Seebeck effect. | |||

Abstract:An efficient method to perform procrustean distillation and concentration for quantum entanglement has been proposed by using one-dimensional anisotropic photonic crystal (PC). The Clauser-Horne-Shimony-Holt parameter for entangled pure state, the quantum relative entropy and linear entropy for mixed state have been calculated theoretically. It is found that the efficiency of such a method is not only much higher for the distillation of non-maximally entangled pure states than those using partial polarizers, it is also good at the concentration for the mixed states. Both the purity and the degree of entanglement of the mixed states can be improved simultaneously several times by using such a method. Another advantage of the scheme is that it can be widely adjusted by a proper choice of the structural parameters of the PC and the external field. A realizable example by using liquid crystals has also been designed and discussed. | |||
