Modified Gravity and Cosmological Dynamics Evaluator

This IXO role evaluates advanced arguments where geometric formalism, differential equations and physical interpretation must remain consistent. Work covers dynamical Chern-Simons gravity, Palatini methods, FRW cosmology and quadratic-inflation settings.

Work you will do

• Derive or inspect first-order Palatini calculations using tetrads and spin connections.
• Evaluate Pontryagin-density terms and explain their consequences within the proposed modified-gravity model.
• Formulate and solve Friedmann equations with torsion, checking the treatment of coupled nonlinear dynamics.
• Integrate nonlinear ODE systems, assess the reliability of the solution and maintain consistent Planck-unit normalization.

Preferred background

• PhD-level or equivalent background in gravitation, cosmology or astrophysics.
• Hands-on use of first-order Palatini methods, tetrad/spin-connection formalism and higher-curvature corrections.
• Ability to derive, solve and interpret nonlinear ODE systems in gravitational or cosmological research.
• Familiarity with Pontryagin density, Chern-Simons modifications and Planck-normalized physical interpretation.

Deliverables

A traceable derivation, numerical solution, technical audit or adjudication with explicit assumptions and consistency checks.
