This study establishes a novel pseudospin framework for non-Hermitian fermionic superfluids, revealing a gapped collective excitation that defies standard Hermitian expectations without the Anderson–Higgs mechanism. By extending BCS theory to include complex pairing interactions, the research identifies how exceptional points fundamentally alter resonance spectra and energy gaps in driven quantum systems. These findings expand the theoretical boundaries of unconventional matter states relevant to future non-Hermitian quantum technologies.
Researchers Detect Novel Phase Mode in Non-Hermitian Superfluids

Gabriel Angelo V. Vila and Kristian Hauser Villegas developed a consistent pseudospin framework for non-Hermitian fermionic superfluids, finding a novel phase mode that has no counterpart in Hermitian superfluids. This mode is gapped, even without the Anderson-Higgs mechanism, and the resonance spectrum depends on the initial nongauge phase of the complex order parameter.
A new theoretical study has identified a previously unknown collective excitation in non-Hermitian fermionic superfluids, expanding the understanding of how these unconventional quantum systems behave. Gabriel Angelo V. Vila and Kristian Hauser Villegas…
