	1. Cover Times in Vibrated Granular Matter

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

	Abstract:This article provides a experimental verification of cover times distribution theory. In real systems, due to the boundary conditions, driving mode and the granular mixtures, the particle's diffusions are usually different from several classic random walks. In this article we investigate two types of granular diffusion: the Brownian motion and the unusual diffusion. We found that the particle's cover time distribution will be affected by boundary effects, and we develop a boundary cutting method to remove that impact. It is observed that the full cover times distribution of super-diffusion and Brownian motion are suitable for the theoretical result in the long-time covering process, but in the short-time covering process, there is a deviation. We think this deviation is due to the long-time approximation.

	Abstract:We simulate the bond and site percolation models on several three-dimensional lattices,including the diamond, body-centered cubic, and face-centered cubic lattices.As on the simple-cubic lattice [Phys. Rev. E, extbf{87} 052107 (2013)],it is observed that in comparison with dimensionless ratios based on cluster-size distribution,certain wrapping probabilities exhibit weaker finite-size corrections and are more sensitiveto the deviation from percolation threshold $p_c$, and thus provide a powerful means for determining $p_c$.We analyze the numerical data of the wrapping probabilitiessimultaneously such that universal parameters are shared by the aforementioned models, andthus significantly improved estimates of $p_c$ are obtained.

	3. Diagonalization of the stationary reduced density matrix in the energybasis
	HE Le-Wei,WANG Wen-Ge
	Physics 12 November 2013
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:It is shown that, if the reduced density matrix (RDM) of an open system may reach a stationary solution for long times, and if the environment of the system has certain random feature, then, in the limit of large Hilbert space of the environment, the stationary RDM is commutable with a renormalized Hamiltonian of the system. Here, the renormalized Hamiltonian is given by the unperturbed Hamiltonian plus certain average of the interaction Hamiltonian over the environmental degrees of freedom. Under the above-mentioned conditions, the eigenbasis of the renormalized Hamiltonian is usually a preferred basis in view of the long-time evolution of the RDM.

	4. Accelerating cycle expansions by dynamical conjugacy
	Ang Gao,Jianbo Xie,Yueheng Lan
	Physics 12 October 2011
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Periodic orbit theory provides two important functions---the dynamical zeta function and the spectral determinant for the calculation of dynamical averages in a nonlinear system. Their cycle expansions converge rapidly when the system is uniformly hyperbolic but greatly slowed down in the presence of non-hyperbolicity. We find that the slow convergence can be associated with singularities in the natural measure. A properly designed coordinate transformation may remove these singularities and results in a dynamically conjugate system where fast convergence is restored. The technique is successfully demonstrated on several examples of one-dimensional maps and some remaining challenges are discussed.

	5. Asymptotic equilibrium inducing metastable chaos

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

	Abstract:It is shown that the asymptotic equilibrium solutions (AES) of a nonlinear equation of motion possess conditional stability. The conditions for controlling instability are derived from a direct perturbation method. Theoretical analysis reveals that the controlling conditions contain Melnikov criterion for the onset of chaos and lead to sensitive dependence of the system on initial conditions and physical parameters. This implies that there exists metastable chaos in the system. Some examples, such as the Duffing oscillator, the rf-driven Josephson junction and other systems, are used to demonstrate the conclusion.

	6. Fraction of the gluonium component in eta' and eta

	Abstract:It is interesting to determine the fraction of the gluonium component in $\eta$ and $\eta'$ which has been under serious discussion for many years. Measurements on different decay and/or production modes were employed in literatures, thus larger uncertainties were unavoidable. In this paper we suggest to determine the mixing angles of $\eta-\eta'-G$ using the data of semileptonic decays of $D$ and $D_s$. We extract the mixing angles $\phi'$, $\phi_G$ and the model parameters simultaneously. Thanks to the new measurements carried out by CLEO Collaboration and there are sufficient decay modes to determine both the model parameters and mixing angles. The mixing angles from data are $\phi'=(41.5\pm2.0)^\circ$ and $\sin\phi_G=0.00\pm0.36$. Even though the central value of $\sin\phi_G$ is still zero, an upper bound is set.

	7. Re-study on the contribution of scalar potential and spectra of c\bar c, b\bar b and b\bar c(c\bar b) families

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

	Abstract:We indicated in our previous work that for QED the roleof the scalar potential which appears at the loop level is much smaller than that of the vector potential and in fact negligible. But the situation is different for QCD, one reason is that the loop effects are more significant because $\alpha_s$ is much larger than $\alpha$, and secondly the non-perturbative QCD effects may induce a sizable scalar potential. In this work, we phenomenologically study the contribution of the scalar potential to the spectra of charmonia, bottomonia and $b\bar c(\bar b c)$ family. Taking into account both vector and scalar potentials, by fitting the well measured charmonia and bottomonia spectra, we re-fix the relevant parameters and test them by calculating other states of not only the charmonia, bottomonia, but also further the $b\bar c$ family. We also consider the Lamb shift of the spectra.

	8. Construction of quaternion coherent state with the use of IWOP method and some useful integration formulas over quaternion

	Abstract:Based on quaternions we try to construct quaternion coherent state (QCS), dueto the noncommutativity of quarternions' multplication some new integrationformulas over quaternions are derived in this paper which helps to find thecompleteness relation of QCS. We also prove that quaternions is the onlypossible natural extension of complex number. Application of QCS in derivingoperator identities is also presented with the use of the integrationtechnique within an ordered product (IWOP) of operators.

	10. A multi-local-world model for complex networks

	Abstract:The nodes in a community within a network are much more connected to each other than to the others outside the community in the same network. This phenomenon has been commonly observed from many real-world networks, ranging from social to biological even to technical networks. Meanwhile, the number of communities in some real-world networks, such as the Internet and most social networks, are evolving with time. To model this kind of networks, the present paper proposes a multi-local-world (MLW) model to capture and describe their essential topological properties. Based on the mean-field theory, the degree distribution of this model is obtained analytically, showing that the generated network has a novel topological feature as being not completely random nor completely scale-free but behaving somewhere between them.
