Optical signatures of Rashba--Dresselhaus coupling across Franz--Keldysh and Landau regimes in two-dimensional semiconductors
This paper presents a unified theoretical framework for the interband optical response of two-dimensional semiconductors with simultaneous Rashba and Dresselhaus spin-orbit couplings, revealing how electric and magnetic fields distinctively modify joint density of states, Landau levels, and Franz-Keldysh oscillations to enable the optical identification and characterization of these spin-orbit interactions.
