Intrinsic Paramagnetic Meissner Effect due to s-wave Odd Frequency Superconductivity

Discussion outcomes/interesting questions:

  • Is there anything topologically non-trivial about Helimagnet-Superconductor, in a thin film geometry? Is it (can it be made e.g. with help of SO) topological for fixed $k_z$, similar to Weyl systems? (possibility raised by by Yuval O.)

  • Would be nice to understand what odd-f superconductivity really is. Connection to Majoranas? (Yip)
