_{2}, superconducting bulk materials have been studied. The peak values of the critical current density J

_{c}, and the exact peak positions together with its corresponding half‐widths for a constant temperature as well as for a constant applied magnetic field have been calculated by considering the quantum,...

^{4}'s can be considered as the natural counterpart for geometry of quantum gravity in some limits. This follows from the relations of these exotics to ℤ

_{2}orientifolds of WZW models on SU(2), abelian gerbes on S
