Collective excitations across the BCS-BEC crossover induced by a synthetic Rashba spin-orbit coupling

Jayantha P. Vyasanakere, Vijay B. Shenoy

Synthetic non-Abelian gauge fields in cold atom systems produce a Rashba spin-orbit interaction described by a vector $\blam = (λ_x, λ_y, λ_z)$. It was recently shown [Phys. Rev. B…
