Coordinates problem of Hawking radiation derivation in a Kerr–Newman black hole using Hamilton–Jacobi equation
Hawking radiation from a Kerr–Newman black hole is investigated using Hamilton–Jacobi method more deeply. A direct computation will lead to a wrong result via Hamilton–Jacobi method. However, when the well-behaved Painleve coordinate system and Eddington coordinate system are considered, we can get the correct result. The reason of the discrepancy between naive coordinate and well-behaved coordinates is also discussed.

Nonequilibrium Thermodynamics of Dark Energy on Cosmic Apparent Horizon
In recent several years, some works have been done on cosmic thermodynamics. The apparent horizon was regarded as the key characteristic supersurface where thermodynamics can be built on perfectly. However, if the irreversible process is considered, the proper position for building thermodynamics will not be the apparent horizon anymore. The new position is related to dark energy state equation and the irreversible process parameters.

Determination of average kinetic energy (μ2π) of a heavy quark inside a heavy vector meson using a relativistic method
The average kinetic energy of a heavy quark inside a heavy vector meson was computed using a relativistic Salpeter method. It was found through computation that significant relativistic corrections result in different values of μ2π for pseudoscalar and vector mesons, and μ2π ≈ 0.41 ± 0.07(B*0, B*±), 0.31 ± 0.06(D*0, D*±), 0.48 ± 0.09(B*s), 0.36 ± 0.07(D*s), 0.96 ± 0.17(B*c), 0.62 ± 0.11(J/Ψ) GeV2 for vector mesons.

Yang-Baxter $${\breve R}$$ matrix, entanglement and Yangian
We present a method to construct “X” form unitary Yang-Baxter $${\breve R}$$ matrices, which act on the tensor product space $${V_{i}^{j_{1}}\otimes V_{i+1}^{j_{2}}}$$ . We can obtain a set of entangled states for (2j1 + 1) × (2j2 + 1)-dimensional system with these Yang-Baxter $${\breve R}$$ matrices. By means of Yang-Baxter approach, a 8 × 8 Yang-Baxter Hamiltonian is constructed. Yangian symmetry and Yangian generators as shift operators for this Yang-Baxter system are investigated in detail.

NSLS-II Transport Line Progress
The National Synchrotron Light Source II (NSLS-II) is a state-of-the-art 3-GeV third generation light source currently under construction at Brookhaven National Laboratory. The NSLS-II injection system consists of a 200 MeV linac, a 3-GeV booster synchrotron and associated transfer lines. The first part of the Linac to Booster Transport (LBT) line has been installed for linac commissioning. This part includes all components necessary to commission the NSLS-II linac. The second part of this transport line is undergoing installation. Initial results of hardware commissioning will be discussed. The Booster to Storage Ring (BSR) transport line underwent a design review. The first part of the BSR transport line, consisting of all components necessary to commission the booster will be installed in 2012 for booster commissioning. We report on the final design of the BSR line along with the plan to commission the booster.

An analysis of the two-vortex case in the Chern-Simons Higgs model
Abstract. Extending work of Caffarelli-Yang and Tarantello, we present a variational existence proof for two-vortex solutions of the periodic Chern-Simons Higgs model and analyze the asymptotic behavior of these solutions as the parameter coupling the gauge field with the scalar field tends to 0.
