	1. Elastic scattering cross sections of the weakly-bound nuclei uc{8}{B} and uc{11}{Be}
	YANG Yan-Yun,PANG Dan-Yang
	Physics 20 May 2016
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Elastic scattering and breakup reactions of uc{8}{B} and uc{11}{Be} with uc{64}{Zn} and uc{208}{Pb}are systematically analyzed from near to the Coulomb barrier energies to about three times of the Coulomb barrier using the continuum-discretised coupled channels method (CDCC). Systematic differences were found in the angular distributions of the elastic scattering cross sections in these two nuclei. It was found that the suppression of the breakup coupling effects to the elastic scattering cross sections of uc{8}{B} was due to the Coulomb and centrifugal barriers experienced by its valence proton.

	Abstract:Deuteron-stripping reaction is one of the most effective tools to study the single-particle structure of atomic nuclei. Optical model potential(OMP) is one of the most important inputs in the calculations of (d,p) reactions. The relativistic systematic microscopic optical potential(RMOP) based on the Dirac-Brueckner-Hartree-Fock theory is used for calculating the angular distributions of proton elastic scattering and (d,p) reactions with the uc{14}{C}, uc{58}{Ni}, and uc{116}{Sn} targets at both low and higher energies. Neutron spectroscopic factors in the ground states of uc{15}{C}, uc{59}{Ni}, and uc{117}{Sn} are extracted by comparing with experimental data. Comparisons with those obtained using phenomenological systematic optical model potentials, KD02 and CH89 show that the RMOP, which has no free parameters, can give reasonable reproduction to the experimental angular distributions. The spectroscopic factors extracted from experimental data using the RMOP, however, differ from those of KD02 and CH89 systematically.

	Abstract:In real worlds, many systems can be better represented as weightednetworks. However, most studies of traffic fluctuations focus onbinary network. This paper studies the traffic fluctuation onweighted networks. Exact expressions for the traffic fluctuation$sigma_i$ as a function of $langle f_i angle$ on node $i$ onBarrat-Barth'elemy-Vespignani (BBV) weighted networks arederived. The effects of four different factors on trafficfluctuations are studied by extensive simulations: (i)the lengthof time window $M$; (ii) the network parameter $m$ of the BBVmodel; (iii) the weight parameter $delta$ of the BBV network; and(iv) the degree of node $k_i$. The results can help to understandthe influences of weight on the behavior of network traffic.

	Abstract:Antiferromagnetic nanoparticles have attracted tremendous research interests due to the discovery of their potentials for exhibiting magnetization reversal by quantum tunneling. The well-dispersed antiferromagnetic nanoparticles are desired because their magnetic properties are sensitive to interparticle separation and polymer molecules, etc. Here we show that graphene may be a potential substrate material for antiferromagnetic nanoparticles to keep their intrinsic magnetic properties. Graphene-Co3O4 nanocomposites are fabricated via a facile low-temperature hydrothermal method from graphene oxide. The Co3O4 nanoparticles anchor uniformly on the reduced graphene oxide surface with a monodispersed grain size of about 7 nm. Compared to the pure Co3O4 nanoparticles with similar grain size, the graphene-Co3O4 nanocomposites show great difference in magnetic properties, including blocking temperature and magnetic hysteresis loop. It was thought that the graphene matrix prevents the aggregation of Co3O4 nanoparticles which leads to the anomalous magnetic properties.

	5. Two-state Markov-chain Poisson nature of individual cellphone call statistics

	Abstract:Unfolding the burst patterns in human activities and social interactions is a very important issue especially for understanding the spreading of disease and information and the formation of group and organization. Here, we conduct an in-depth study of the temporal patterns of cellphone conversation activities of 73,339 anonymous cellphone users, whose inter-call durations are Weibull distributed. We find that the individual call events exhibit a pattern of bursts, that high activity periods are alternated with low activity periods. In both periods, the number of calls are exponential distributed for individuals, but power-law distributed for the population. Together with the exponential distributions of inter-call durations within bursts and of the intervals between consecutive bursts, we demonstrate that the individual call activities are driven by two independent Poisson processes, which can be combined within a minimal model in terms of a two-state first-order Markov chain, giving significant fits for nearly half of the individuals. By measuring directly the distributions of call rates across the population, which exhibit power-law tails, we purport the existence of power-law distributions, via the "Superposition of Distributions" mechanism. Our findings shed light on the origins of bursty patterns in other human activities.

	Abstract:In this paper, the photon statistics of pulse pumped four wave mixing in fibers with weak coherent signal injection are studied by measuring the intensity correlation functions of individual signal and idler fields. The experimental results show the intensity correlation function of individual signal (idler) field decreases with the intensity of signal injection. After applying narrow band filter in signal (idler) band, the value of decreases from 1.9±0.02 (1.9±0.02) to 1.03±0.02 (1.05±0.02) when the intensity of signal injection varies from 0 to 120 photons/pulse. The results indicate that the photon statistics changes from Bose-Einstein distribution to Poisson distribution. We calculate the intensity correlation functions by using the multimode theory of four wave mixing in fibers. The theoretical curves well fit the experimental results. Our investigation will be useful for mitigating the crosstalk between quantum and classical channels in a dense wavelength division multiplexing network.

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:An organic polymer consists of a large density of cross-links and alternating connectivity of radical modules with unequal spin quantum numbers, which shows the diamond chain. The effective-field theory with correlations has been employed to study the magnetic and thermodynamic properties of the system. A number of feature behaviors which heavily depend on the on-site anisotropy are shown, such as the existence of two compensation points for appropriate values of the anisotropy and others parameters.

	8. An Explanation for Heavy Quark Energy Loss Puzzle by Flow Effects

	Physics 05 May 2016
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:The heavy quark energy loss puzzle is explained by collective floweffects in a dynamic medium. The dead cone and LPM effect are foundto be changed comparing to the static medium case. The collectiveflow induces difference of two dead cones in two differentkinds of processes. One is from the projectile emitting gluonprocess, the same as that in the static medium. The other is fromthe gluon emission off the exchanged gluon process, decreasing withincreasing flow velocity $v_z$ along jet direction, which lead tothe increase of heavy quark energy loss. The differences in theeffective average energy loss among charm, bottom and light quarksare very little from a full 3D ideal hydrodynamic simulation for0-10$%$ central Au-Au collisions at RHIC energy. This would yieldsimilar high $p_{T}$ suppressions between light and heavy quarks forcentral Au-Au collisions.

	9. Generation and manipulation of infrared solitons in Landau-quantized graphene
	DING Chunling,YU Rong,LI Ruoping,ZHANG Duo
	Physics 04 May 2016
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Here we present an analytical and numerical analysis of the soliton formation and manipulation in Landau-quantized graphene. We find that the results of numerical simulations from density-matrix equations without any approximations are consistent with the analytical expressions of bright and dark solitons by virtue of slowly varying envelope approximation and perturbation theory. The mechanism of soliton generation is ascribed to the balance between the nonlinearity-induced self-phase modulation and dispersive spreading. Also, the unusual electronic band structure and unique optical properties of graphene provide more degrees of freedom for us to manipulate the formation and propagation of infrared solitons in graphene ensemble. Our investigations have potential implications in telecommunication and solid-state quantum information processing.

	Abstract:In this paper, we studied the effects on microstructure, ferroelectric and photovoltaic property of different Cr3+ dopants concentrations for Pb(Zr0.2Ti0.8)O3 (PCZT) ferroelectric films. Our experimental results showed that Cr3+ ions, as the accepters substituting for Ti4+ ions, decreased the remnant polarization (2Pr) when Cr3+ concentration was less than about 1% (molar ratio). However, Cr3+ ions were the donors substituting for Pb2+ ions and 2Pr was improved greatly when Cr3+ concentration was more than about 1%. The ferroelectric and photovoltaic outputs of PCZT films were optimized.When the concentration of Cr3+ ions was about 3%, the value of 2Pr reached 124.44 μC/cm2, which was about 2.8 times compared with that of PZT film (no Cr3+ dopants, 45.15 μC/cm2). Accordingly, the photovoltaic output of PCZT film (Cr3+ dopants 3%) was about 5 times compared with that of PZT film.
