Teams building research-grade models need physicists who can solve, audit and adjudicate hard theoretical problems, and say clearly where a solution goes wrong. Your evaluations help improve the accuracy and reasoning of scientific AI answers. This is remote, part-time contractor work applying your statistical-physics expertise to AI evaluation.\nWhat you'll do\nWork through problems on the Nishimori line, toric-code thresholds, and replicated random-bond Ising and Ashkin-Teller models\nWrite documented solutions or critiques using square-lattice self-duality, Kramers-Wannier duality, quenched disorder averaging and domain-wall free energy\nRun 4-state Potts model simulations, interpret the results, and look into noncontractible loop defects and other topological features\nTake the Solver, Auditor or Adjudicator role on assigned projects\nWhy this is worth your time\nEarn $100-$200 an hour solving and reviewing theoretical physics problems from your own subfield\nWork on problems taken from statistical physics, topological quantum codes and condensed matter theory\nApply your research judgment to check whether AI-generated physics solutions are correct and well supported\nFully remote and flexible, no fixed shifts, no commute\nWho this is for\nA physics PhD or equivalent experience, with a specialty in statistical physics, quantum information or condensed matter theory\nHands-on experience with square-lattice self-duality, Kramers-Wannier duality and quenched disorder averaging\nNumerical simulation and analysis work on domain-wall free energy and the 4-state Potts model\nKnowledge of topological quantum codes, above all the toric code and its threshold behavior\nFluent in English\nHelpful: Python, SymPy, Jupyter, and LaTeX, plus a strong record of 3 to 5 relevant papers published in the last 5 years\nNo AI experience needed. You bring the physics expertise; your judgment helps evaluate and improve AI-generated physics solutions.\nPay and details\n$100-$200 per hour, paid hourly as an independent contractor\nPart-time, flexible schedule; fully remote, United States\nHow to apply\n1.
