u BCS 理论(BCS theory)是解释常规超导体的超导电性的微观理论(所以也常意译为超导的微观理论);不过,BCS理论并无法成功的解释所谓第二类超导,或高温超导的现象。 u BCS 理论标志着超导电性理论现代阶段的开始 。u

modified weak-coupling theoryenergy dependenceIn this paper we derive an expression for the superconducting transition temperature of a uranium-based heavy-fermion system within a modified weak-coupling theory of superconductivity. It is found that the energy dependence of the enhanced density of states...

Our approach combines the BCS self-consistency condition, a semiclassical expansion for the spectral density and interaction matrix elements, and corrections to the BCS mean-field. In chaotic grains mesoscopic fluctuations of the matrix elements lead to a smooth dependence of the order parameter on ...
When the trial spaces are chosen to be of the independent-quasi-particle type, we obtain an extension of the Hartree–Fock–Bogoliubov theory which optimizes the characteristic function. The expansion of the latter in powers of its sources yields for the fluctuations and correlations compact ...
BCS theory of hole superconductivity: Quasi-two-dimensional model Recent work on the mechanism of hole superconductivity is generalized to include interplanar hopping. The particular nature of the pairing interaction caus... F Marsiglio,JE Hirsch - 《Physica C Superconductivity》 被引量: 36发表: 1989...
BCS theory and its developmentdegenerate fermi gasesWe derive upper and lower bounds on the critical temperature $T_c$ and theenergy gap $\\Xi$ (at zero temperature) for the BCS gap equation, describingspin 1/2 fermions interacting via a local two-body interaction potential$\\lambda V(x)$...
Quantum Field Theory. II. Numerical Calculations We solve numerically various types of the gap equations developed in the relativistic BCS and generalized BCS framework, presented in part I of this paper. We apply the method for not only the usual solid metal but also other physical sy... T ...
