Beyond the conventional nuclear superfluidity: triplet and mixed-spin superfluids across nucleonic systems, pairing at the drip-line, and more

Abstract: Pairing of nucleons is a well-known property of nuclei and nucleonic matter and the mechanism driving nuclear superfluidity. While it bears a connection to the fermionic superfluidity encountered in terrestrial superconductors, various aspects of nuclear superfluidity are unique holding unanswered questions: Does the analogue of triplet superfluidity exist for neutron-proton pairs in nuclei? Can opposite parity order parameters coexist in nucleonic systems? What are the properties of the superfluid state in weakly bound states? Are these effects unique to nuclear systems? I will present new theoretical results in these directions, using a mix of phenomenological and ab initio many-body methods, and connect them to two recent precision mass measurement with TITAN at TRIUMF. Finally, in this talk I also intend to discuss other works, notably recent attempts to refine the description of microscopic three-nucleon forces.
