Visual Image of Cooper Pairing in Superconductors

چکیده
In this paper, we provide a dynamic geometric imaging of the isosymmetries, which characterize the mutual contact/penetration of paired electron wavepackets in the isostandard model of cooper pairs in superconductors. This is accomplished by modifying the theoretical framework developed by researchers at Howard University. In their model, the Howard group based their approach on the classical Hamiltonian Hi = p i − eA c ( ) 2 + mic 2 + V ( )2 , i = 1,2 , which showed the clear power of the isotopic method. As an application, in this paper, we consider a representation of the usual quantum mechanical non-relativistic quasiparticle energy in (k-space) of a Cooper pair, Ek = εk 2 + Δk ( ) , as an eigenvalue of a 4 × 4 Hamiltonian matrix, Hk = εkg ± Δk ĝ , involving the conventional Minkowski metric g = diag 1,−1,−1, −1 [ ] and its isotope ĝ = βg . The β -matrix here is the 4 × 4 antisymmetric matrix introduced by Dirac in his construction of a positive energy relativistic wave equation for an integral spin particle. We find a new class of dynamic geometric images in space-time as isominkowskian spaces define by, s = x gμν ± ξĝμν ( )x , 0 ≤ ξ ≤ 1 , which represents a pair of spheres in contact when x = s and ξ = 1 . The physical implications are discussed.

Magnetic excitations as driving force of superconductivity in CeCu2Si2
Coexistence or competition of superconductivity and magnetic order remains an important issue in condensed matter physics. While conventional superconductivity is generally incompatible with magnetism, the magnetic 4f or 5f moments in heavy-fermion superconductors play a crucial role for the appearance of unconventional superconductivity. Similar to the high-temperature cuprate superconductors,...
متن کاملCorrelation between characteristic energies in non–s-wave pairing superconductors
By solution of the Bethe-Goldstone equation for the Cooper pairing problem, an approximate analytic relation is derived between coherence length ξ and the binding energy of the Cooper pair. This relation is then qualitatively confirmed by numerically solving the corresponding self-consistent gap equations, following the crossover from weak to strong coupling, in non–s-wave superconductors. The ...

To understand the mechanism of superconductivity in unconventional super onductors is one of the big challenges in the field of superconductivity. Based on the BCS theory, there is a direct relation between the pairing mechanism and the symmetry of the order parameter. Therefore, identification of the structure of the superconducting gap or the order parameter provides key information on the pa...

We use scanning tunneling microscopy to investigate the doping dependence of quasiparticle interference (QPI) in NaFe1-xCoxAs iron-based superconductors. The goal is to study the relation between nematic fluctuations and Cooper pairing. In the parent and underdoped compounds, where fourfold rotational symmetry is broken macroscopically, the QPI patterns reveal strong rotational anisotropy. At o...
