Two generalizations of Cheeger-Gromoll splitting theorem via Bakry-\'{E}mery Ricci curvature (2007)
Fang, Fuquan, Li, Xiangdong, Zhang, Zhenlei
In this paper, we prove two generalized versions of the Cheeger-Gromoll splitting theorem via the non-negativity of the Bakry-\'Emery Ricci curavture on complete Riemannian manifolds.
Post-Quantum Key Exchange Protocols (2006)
Li, Xiangdong, Leung, Lin, Kwan, Andis Chi-Tung, Zhang, Xiaowen, Kahanda, Dammika, Anshel, Michael
If an eavesdropper Eve is equipped with quantum computers, she can easily break the public key exchange protocols used today. In this paper we will discuss the post-quantum Diffie-Hellman key...
Low Mass X-ray Binary As the Progenitor of PSR J1713+0747 (2005)
Chen, Wencong, Li, Xiangdong, Wang, Zhenru
We have calculated the evolution of low-mass X-ray binaries that leads to the formation of the binary radio pulsars like PSR J1713+0747. We show that the mass transfer is most likely to be...
Relativistic Model of Triquark Structure (2005)
Li, Hu, Shakin, C. M., Li, Xiangdong
At this point it is still unclear whether pentaquarks exist. While they have be seen in some experiments there are many experiments in which they are not found. On the assumption that pentaquarks...
Relativistic Calculation of Pentaquark Widths (2005)
Li, Hu, Shakin, C. M., Li, Xiangdong
We calculate the widths of the various pentaquarks in a relativistic model in which the pentaquark is considered to be composed of a scalar diquark and a spin 1/2 triquark. We consider both positive...
Relativistic Calculation of the Width of the Theta (1540) Pentaquark (2005)
Li, Hu, Shakin, C. M., Li, Xiangdong
We calculate the width of the Theta(1540) pentaquark in a relativistic model in which the pentaquark is considered to be composed of a scalar diquark and a spin 1/2 triquark. We consider both...
Quark Propagation in the Presence of a A_\mu^aA_a^\mu> Condensate (2004)
There is a good deal of current interest in the condensate g^2A_\mu^aA_a^\mu> which has recently be shown to be the Landau gauge version of a more general gauge-invariant expression. In the present...
Comparison of Models of Critical Opacity in the Quark-Gluon Plasma (2004)
In this work we discuss two methods of calculation of quark propagation in the quark-gluon plasma. Both methods make use of the Nambu-Jona-Lasinio model. The essential difference of these...
Li, Xiangdong, Li, Hu, Shakin, C. M., Sun, Qing, Wang, Huangsheng
We have calculated spectral functions associated with hadronic current correlation functions for vector currents at finite temperature. We made use of a model with chiral symmetry,...
Calculation of Screening Masses in a Chiral Quark Model (2004)
Li, Xiangdong, Li, Hu, Shakin, C. M., Sun, Qing
We consider a simple model for the coordinate-space vacuum polarization function which is often parametrized in terms of a screening mass. We discuss the circumstances in which the standard result...
Quark Propagation in the Quark-Gluon Plasma (2004)
Li, Xiangdong, Li, Hu, Shakin, C. M., Sun, Qing
It has recently been suggested that the quark-gluon plasma formed in heavy-ion collisions behaves as a nearly ideal fluid. That behavior may be understood if the quark and antiquark mean-free- paths...
Li, Xiangdong, Li, Hu, Shakin, C. M., Sun, Qing, Wang, Huangsheng
We calculate spectral functions associated with hadronic current correlation functions for vector currents at finite temperature. We make use of a model with chiral symmetry, temperature-dependent...
