Gluonium as Bound State of Massive Gluons Described by the Joos-Weinberg Wave Functions

On the basis of the Kadyshevsky equal-time (quasipotential) approach, a set of partial-wave equations is derived for the wave function of a gluonium, a bound state of two gluons. The field operators of constituent gluons are considered as six component quantities according to the Joos-Weinberg $2(2S+1)$- component approach. The quasiclassical quantization condition for relativistic two-particle states and the above set could be used for calculations of gluonium energy levels.Comment: LaTeX file. 15 pp., 1 postscript figur

Poor fluorinated graphene sheets carboxymethylcellulose polymer composite mode locker for erbium doped fiber laser

We report poor fluorinated graphene sheets produced by thermal exfoliation embedding in carboxymethylcellulose polymer composite (GCMC) as an efficient mode locker for erbium doped fiber laser. Two GCMC mode lockers with different concentration have been fabricated. The GCMC based mode locked fiber laser shows stable soliton output pulse shaping with repetition rate of 28.5MHz and output power of 5.5 mW was achieved with the high concentration GCMC, while a slightly higher output power of 6.9 mW was obtained using the low concentration GCMC mode locker
