Pairing symmetry and long range pair potential in a weak coupling theory of superconductivity
We study the superconducting phase with two component order parameter
scenario, such as, , where . We show, that in absence of orthorhombocity, the usual
does not mix with usual symmetry gap in an anisotropic band
structure. But the symmetry does mix with the usual d-wave for . The d-wave symmetry with higher harmonics present in it also mixes with
higher order extended wave symmetry. The required pair potential to obtain
higher anisotropic and extended s-wave symmetries, is derived by
considering longer ranged two-body attractive potential in the spirit of tight
binding lattice. We demonstrate that the dominant pairing symmetry changes
drastically from to like as the attractive pair potential is obtained
from longer ranged interaction. More specifically, a typical length scale of
interaction , which could be even/odd multiples of lattice spacing leads
to predominant wave symmetry. The role of long range interaction on
pairing symmetry has further been emphasized by studying the typical interplay
in the temperature dependencies of these higher order and wave pairing
symmetries.Comment: Revtex 8 pages, 7 figures embeded in the text, To appear in PR
The influence of fluorinated MWCNT distribution quality on the mechanical properties of the bulk oriented UHMWPE-based composites
The bulk oriented UHMWPE-based composites were obtained. Fluorinated carbon nanotubes were used as a reinforcing filler. The filler contributes in the formation of nanofibrillar supramolecular structure, that in its turn acts as the harder phase in the nanocomposites synthesized. The influence of the quality of the carbon nanotubes distribution on the mechanical properties under tension was shown
