Enhanced Fermion Pairing and Superfluidity by an Imaginary Magnetic Field

We show that an imaginary magnetic field (IMF), which can be generated in non-Hermitian systems with spin-dependent dissipations, can greatly enhance the s-wave pairing and superfluidity of spin-1/2 fermions, in distinct contrast to the effect of a real magnetic field. The enhancement can be attribu...
