Remote | Physics Expert (Condensed Matter / Quantum Information) — $100–$170/hour

We are sharing a specialised consulting opportunity for experienced Physics Experts in condensed matter physics, quantum information, and related many-body systems with strong expertise in exact diagonalisation, symmetry reduction, block-diagonalisation, QuSpin, Rydberg blockade, quantum many-body scars, and constrained quantum dynamics.

Selected professionals will contribute to a frontier research-level benchmark involving the PXP model, Rydberg-blockaded systems, large Hilbert spaces, symmetry-resolved exact diagonalisation, and Z2-state overlap analysis. Contributors may serve as Solvers, Auditors, or Adjudicators depending on expertise and seniority. No prior experience in AI is required.

Key Responsibilities

Exact Diagonalisation & Symmetry Methods

• Develop exact diagonalisation workflows for constrained many-body systems
• Apply translation and reflection symmetries to construct reduced Hilbert-space sectors
• Perform block-diagonalisation of many-body Hamiltonians
• Work with large system sizes, including L = 26
• Validate numerical implementations against expected physical behaviour

PXP, Rydberg & Many-Body Analysis

• Analyse the PXP model, Rydberg blockade, and constrained quantum dynamics
• Compute and interpret overlaps with Z2 and related states
• Identify signatures associated with quantum many-body scars and non-ergodic dynamics
• Relate numerical spectra and state structure to underlying many-body physics
• Use QuSpin or custom numerical approaches where appropriate

Research Evaluation & Adjudication

• Develop rigorous solutions as a Solver
• Audit calculations, code, symmetry assignments, and physical interpretations
• Compare alternative numerical approaches and adjudicate competing solutions
• Identify conceptual, mathematical, or implementation errors
• Document reproducible methods and research-level technical conclusions clearly

Ideal Profile

• PhD or equivalent research experience in condensed matter physics, quantum information, or a closely related field
• Strong expertise in exact diagonalisation and Hamiltonian block-diagonalisation
• Experience with translation and reflection symmetries and reduced Hilbert spaces
• Practical experience with QuSpin is highly valuable
• Strong understanding of the PXP model, Rydberg blockade, and quantum many-body scars
• Experience with constrained quantum dynamics and Z2-state overlap analysis
• Strong numerical and computational physics skills
• Ability to interpret numerical results in physically meaningful terms
• Strong scientific-writing and research-review skills
• No prior AI-training or model-evaluation experience is required

Engagement Details

• Independent contractor engagement
• Fully remote
• Compensation: $100–$170/hour
• Work will involve exact diagonalisation, symmetry resolution, block-diagonalisation, QuSpin, Z2 overlap analysis, PXP physics, Rydberg blockade, and quantum many-body scar evaluation
• Experience with translation and reflection symmetries for system sizes including L = 26 is particularly relevant
• Contributors may participate as Solvers, Auditors, or Adjudicators depending on expertise and seniority
• Assignments may involve Hamiltonian construction, symmetry sectors, numerical spectra, state overlaps, constrained dynamics, and research-level benchmark evaluation
• Project scope, workload, technical questions, and evaluation standards may evolve depending on project requirements
• Work must be completed without using confidential or proprietary information belonging to any employer, research institution, laboratory, collaborator, or other third party
