Derives WGC bounds q/(m r+) ≥ 1/√2 (universal, parameters cancel) in dRGT gravity and q/(m r+) ≥ e^{-γ/2} in ModMax theory from CFT pole analysis, with relaxed forms when assumptions are dropped.
A review summarizing advancements over the past two years that link DESI baryon acoustic oscillation data to string-inspired scenarios with dynamic dark energy.
String theory offers classes of inflationary models from type IIB Kaehler moduli and dynamical dark energy models, with a working axion hilltop quintessence construction that stresses initial conditions.
