RSFQ (Rapid-Single-Flux-Quantum) logic family is a new type of technology in superconducting digital circuits, in which the information is carried in the presence or absence of SFQ voltage pulses generated by damped Josephson junctions.

It is found that the system in ferromagnetic (FM) phase is dominated by single magneton scattering showing metallic-type conduction which can be fitted by the formula ρ=ρ_0+AT~2, here ρ is res.

It is shown that the magnetic monopole and the electric monopole can be generated on an unified model based on the Hopf bundle ( S 3=S 2×S 1 ) with the structure group U (1) .

Using quantion theory,this paper researches existence of magnetic monopole,and further,obtains the important characteristics about quantization of electric charge.

This paper discusses the existence of the magnetic monopole, the conclusion of which is that the magnetic monopole does not exist in the material world but exists in the hypothetical vacuum world.

Locomotion radiation of monopole by parabola in plasma;

Base on the current density caused by the moving monopole,the hyperbola radiation spectrums of monopole in the central force-field are studied in detail and numerical value calculated in this paper.

In this paper, the locomotion radiation of monopole by conical section and modulation instability of intense linearly polarized laser pulse are studied in plasma, based on the dispersion character of plasma dielectric.
