- Abstract: We discuss pairing of light-matter bosons under effective spin-orbit (SO)
coupling in two-dimensional semiconductors. The SO coupling is shown to induce
dynamical broadening of a two-body bound state. Application of a transverse
magnetic field yields the rich Feshbach resonance phenomenology. We predict
quantum bosonic halos with a synthetic angular momentum L=2. The d-wave-like
dressing of the nominally s-wave bound state is induced by SO coupling to the
continuum in the open channel. The fundamental properties of the emergent
quantum number remain to be explored.

We propose an interferometric method to probe pair correlations in a gas of spin-1/2 fermions.
The method consists of a Ramsey sequence where both spin states of the Fermi gas are set in a superposition of a state at rest and a state with a large recoil velocity.
The off-diagonal long-range order is directly reflected in the behavior of the interferometric signal for long interrogation times.

Key ingredients are tightly bound biexcitons and in-plane anisotropy of the host structure due to, e.g., a uniaxial strain.
We show that anisotropy-induced splitting of the radiative exciton doublet couples the biexciton state to continua of boson scattering states.
