Résumé du poste

ixolabs.ai seeks a remote expert to advance gravity research, evaluating geometric formalism and differential equations within a modified-gravity framework. The role focuses on ensuring consistent physical interpretation across complex models.

Key tasks include deriving Palatini calculations, solving nonlinear ODEs, and evaluating Friedmann equations with torsion while maintaining Planck-unit normalization. This is a paid remote engagement tied to project experience.

Qualifications

• 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.

Responsabilités

• Deliver traceable derivations, numerical solutions, technical audits or adjudications with explicit assumptions.
• Support and advance the proposed modified-gravity model through rigorous analysis.

Description du poste

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.
