We develop a rigorous, field-theoretical approach to the study of spontaneousemission in inertial and dissipative nematic liquid crystals, disclosing analternative application of the massive Stueckelberg gauge theory to describecritical phenomena in these systems. This approach allows one not only tounveil the role of phase transitions in the spontaneous emission in liquidcrystals but also to make quantitative predictions for quantum emission inrealistic nematics of current scientific and technological interest in thefield of metamaterials. Specifically, we predict that one can switch on and offquantum emission in liquid crystals by varying the temperature in thevicinities of the crystalline-to-nematic phase transition, for both theinertial and dissipative cases. We also predict from first principles the valueof the critical exponent that characterizes such a transition, which we shownot only to be independent of the inertial or dissipative dynamics, but also tobe in good agreement with experiments. We determine the orientation of thedipole moment of the emitter relative to the nematic director that inhibitsspontaneous emission, paving the way to achieve directionality of the emittedradiation, a result that could be applied in tuneable photonic devices such asmetasurfaces and tuneable light sources.
