Role Title: Physics Expert (Gravitation / Cosmology / Astrophysics)
Role Type: Contractor
Location: Remote
micro1 is engaging Physics Experts (Gravitation / Cosmology / Astrophysics) to participate in an advanced, research-driven project for a valued customer. In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters.
This opportunity focuses on contributions to a frontier research-level physics benchmark spanning Dynamical Chern-Simons gravity, the Palatini tetrad formalism, FRW cosmology, quadratic inflation, and related phenomena. Based on your expertise, you may be considered for specialized assignments such as Solver, Auditor, or Adjudicator, with specific scopes and deliverables aligned to your subfield experience.
Scope of Work
- Provide detailed analytical and numerical solutions to problems involving Palatini gravity (first-order formalism), including tetrad and spin connection approaches.
- Calculate and analyze Pontryagin density contributions and their implications in extended gravity theories.
- Formulate, solve, and interpret Friedmann ODEs with torsion and their relevance in cosmological models.
- Integrate coupled, nonlinear ODEs using advanced methods and critically evaluate results.
- Apply Planck-unit normalization in all theoretical and computational tasks to ensure consistency and comparability.
Preferred Qualifications
- Advanced academic background (PhD or equivalent) in physics, with emphasis on gravitation, cosmology, or astrophysics.
- Hands-on experience working with first-order Palatini gravity, tetrad and spin connection formalisms, and higher-order curvature corrections.
- Proven ability to derive, solve, and interpret nonlinear ODE systems relevant to cosmology and gravitational physics.
- Familiarity with Pontryagin density, Chern-Simons modifications, and their physical implications.
- Demonstrated experience with Planck-unit normalization and physical interpretation in theoretical models.
