Competition and coexistence of superconductivity and nematic order in a two-dimensional electron gas with quadrupolar interactions
This work investigates how superconductivity and nematic order interact in a 2D electron gas using competing pairing and quadrupolar interactions. The study uses a mean-field model to map out zero-temperature phase diagrams, revealing competition, coexistence regions, and first-order transitions between s-wave, d-wave superconductivity, and nematic phases.
