The non-zero tensorial components in the d3DDM are dictated by presence of a preferred z direction and in contrast to the s3DDM the tensorial components are s-wave, and turn out to be spin-triplet which implies that the tensorial induced superconductivity in d3DDM is odd-frequency as well. Therefore the four-vector and tensor superconductivity induced into d3DDM is odd-frequency. Moreover in d3DDM no superconducting order proportional to unit matrix can be found, which implies that the induced superconductivity in d3DDM is by de?nition unconventional. In the case of s3DDM this scalar superconductivity is controlled by the product mµ and hence for gapless s3DDM at any µ or for particle-hole symmetric band with any-gap again the scalar superconductivity vanishes. Therefore the 3DDMs provide a very interesting playgroundfor unconventionalinducedsuperconductivityin terms of pseudo-scalar or pseudo-vector, odd-frequency, and tensorial character. Even the familiar vector superconducting order parameter in 3DDM can be further classi?ed into time-like and space-like vector superconducting orders. Understanding the interplay between various such orders and their experimental consequences35 requires further investigation.

there is a lot of crazy scalar dyamic info in this joint effort from the Germans and Iranians.
