本文推导出一组表征Jaynes-Cummings模型量子统计性质的表达式。它们可以用来全面描述二能级原子与单模辐射场相互作用中的动力学行为和统计特征。作为例子,详细讨论了二能级原子与真空场的相互作用以及处于激发态的原子与相干场的相互作用。最后指出了上述理论研究的实际意义。

By considering the one-loop radiative corrections,we discussed the symmetry breaking of a specific superstringinspired model based on the gauge group SU(3)C×SU(2)L×SU(2)R×U(1)′×U(1)′′ We discussed phenomenologically the neutrino mass problem,and the value of the soft breaking parameters A,m and M at the scale Mx were given. 相似文献

Based on the many-body theory of confined quarks and gluons[l], the ultraviolet divergence of the self energy in the bag model is discussed. It is shown that for massless quark the self energy is finite and it is 1ogarithmically divergent for massive quark. The numerical calculation is performed for m=0 and m=1.0(in unit 1/R). The self energy has important effects on the bag model and changes the parameters in this model considerably. Furtherstudy of selfenergy and mass renormalization is necessary. 相似文献

For a system described by the interacting boson-fermion model (IBFM),we construct the intrinsic states and study the moment of inertia of deformed odd-A nuclei in terms of the selfconsistent cranking calculation.An approximate analytic method for the energy spectrum is presented in the general cases where the IBFM Hamiltonian does not have dynamical symmetry.The rationality of this method is also discussed by taking 153,155,157Eu isotopes as examples. 相似文献

Fission process is considered as a multidimensional Brownian motion. The Planck-Fokker equation is solved and the fission probability in the steady state approximationis calculated. The results is compared with the Bohr-Wheeler theory. Numerical cal-culations are performed for the fission of 236U and the results are discussed. 相似文献

In this paper the virtual exchange effect of pseudoscalar mesons in the MZT bag model is discussed and the mass spectrum of hadrons,the magnetic moment's and the mean square values of charge radius are calculated. It is pointed out that our model can pre-serve and improve the static properties of the MIT bag model and provide an explanation for the origin of the meson cloud outside. 相似文献
