	1. 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

	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.

	2. Thermosize Effects of Ideal Fermi Gases Confined in Micro/Nano-Scale Tubes
	Su Guozhen,Chen Liwei,Lin Tongling,Chen Jincan
	Physics 09 March 2011
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:It is found that when two micro/nano-scale tubes of different areas of cross sections filled with identical Fermi gas are connected to each other and the two junctions are kept at different temperatures, the finite-size effect will result in the "thermosize effects", which are analogous to thermoelectric effects in conductors and/or semiconductors. Expressions for the important parameters related to the thermosize effects, including the Seebeck-like chemical potential difference, Peltier-like heat, and Thomson-like heat, are derived in the cases of both strong degeneracy and nondegeneracy. It may be expected that there will be some novel practical applications for these thermosize effects.

	3. performance characteristic and parametric optimization of an irreversible magnetic Ericsson heat pump
	WEI Fang,LIN Guoxing,CHEN Jincan,Ekkes Bruck
	Physics 17 February 2011
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:By taking account of finite-rate heat transfer in the heat-transfer processes, heat leak between the two external heat reservoirs, regenerative loss, regeneration time, and internal irreversibility due to dissipation of the cycle working substance, an irreversible magnetic Ericsson heat pump cycle is presented. On the basis of the thermodynamic properties of magnetic materials, the performance characteristics of the irreversible magnetic Ericsson heat pump are investigated and the relationship between the optimal heating load and the coefficient of performance (COP) is derived. Moreover, the maximum heating load and the corresponding COP as well as the maximum COP and the corresponding heating load are obtained. Furthermore, the other optimal performance characteristics are discussed in detail. The results obtained here may provide some new information for the optimal parameter design and the development of real magnetic Ericsson heat pumps.

	Abstract:An irreversible Stirling heat pump cycle using ferromagnetic materials as a cyclic working substance is established. The influences of finite-rate heat transfer, heat leak, regeneration time, regenerative loss and the internal irreversibility on the cyclic performance of magnetic heat pumps are taken into account. On the basis of the thermodynamic properties of ferromagnetic materials, the performance characteristic of the ferromagnetic Stirling heat pump cycle is investigated. Also, by applying the optimal-control theory, the relation between the optimal heating load and the coefficient of performance (COP) is derived. Furthermore, the maximum heating load and the corresponding COP as well as the maximum COP and the corresponding heating load are determinded and discussed in detail. The results obtained in the present paper may provide some new information for the optimal design and the development of real magnetic heat pumps.

	5. The study of Curved D1 Brane

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

	Abstract:we restrict the open string end on the circular Brane. The variation of Bosonic string's action give the Bosonic boundary condition. Expanding to the supersymmetry string's action, and requiring the boundary conditions are invariant under supersymmetry, we get the supersymmetry boundary condition. Using the solutions of the string equantion ,the boundary condition could be simplified and the boundary state is obtained when R>>alpha_1/2. The boundary state satisfys some restrictions by the super-Virasoro generators, is BRST invariant after add the ghost. At last we give the boundary state of general curving D1 brane. t

	6. New exact solutions of a stratified fluid model

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

	Abstract:The stratified fluid model derived from the low-Froude-number theory of the rotating stratified turbulence can describe broad vortical flows ranging from large scale to the atmospheric mesoscale and the oceanic submesoscale. A general relation of the model with the famous Euler system is established. From the vortex and circumstance solution of the Euler equation, we construct a new exact explicit solution. In detail, we discuss that the solution with particular selections of the arbitrary functions captures the characteristics of the three dimensional spiral pattern for typhoon.

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

	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.

	9. Quantum Diffusion Front of an Electron in Aperiodic Lattices

	Physics 14 January 2011
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:In this paper, the quantum diffusion front of an electron moving in aperiodic lattices is studied by numerical methods. It is found that the stretched exponential quantum diffusion front, founded originally by Zhong et.al. for electron in the random and Fibonacci lattices, is not universal for electron in some of aperiodic lattices, such as period-doubling and Thue-Morse lattices. And it is found by analyzing the properties of the uniform case that the reason of this non-universal behavior is the extended eigenstates in these systems.

	10. Renormalizability and Nonrenormalizable Interactions
	Yao Haibo,Wu Shishu
	Physics 03 January 2011
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Arguments are provided which show that extension of renormalizability in quantum field theory is possible. By an appropriate choice of effective Lagrangian, a dressed Feynman propagator is obtained. In this scheme, higher order Feynman diagrams become self-convergent and nonrenormalizable interactions become renormalizable. As an example, the vacuum fluctuation effects on ho meson mass for the vector-tensor coupling model is discussed. It is found that the result can agree with the experimental value when coupling constant is adjusted.
