Emergent $${{{{{{{\mathcal{PT}}}}}}}}$$ PT -symmetry breaking of collective modes with topological critical phenomena
Breaking of parity-time (PT) symmetry in non-Hermitian systems can lead to a range of unusual physical properties and, in the case of many-body systems, exotic critical behaviour. Here, the authors theoretically consider a PT-symmetric Fermi superfluid, demonstrating emergent PT symmetry breaking in...
