  We report on the flavour physics of mesoscopic instantons found primarily in
a pure Nb metal, doped magnetically by long-lived Mossbauer 93mNb gamas. A giga
fine-structure constant NI*alpha characterizes various properties of the
soliton, in which NI ~ 3 * 10^10 is the instanton number. A hierarchy of
photonic solitons is classified into six flavours, i.e., three generations in
each of two homotopy classes. The underdoped metallic heterostructure contains
two topologically distinct sectors. When the gama-dopant filling factor > 0.88,
the nontrivial sector becomes a chiral superfluid at T >> 300 K to provide a
gama-clock Q-factor > 10^27 for some decades, while the trivial sector becomes
a superconductor below 9.3 K. Distinct soliton flavours carrying Kopnin masses
> 14 PeV, Majorana mass < 36 aeV, and nuclear B > 35000 T imply a range of
possible applications, e.g., topological quantum computation and the detection
of invisible particles.
