Real-time radical-pair magnetoreception simulation framework driven by geomagnetic activity streams.
SpinLab is the first integrated platform linking real-time geomagnetic activity data directly to radical-pair quantum spin dynamics simulations. It transforms static field-sweep analyses into dynamic sensing experiments, enabling systematic investigation of magnetoreceptor performance across the full spectrum of geomagnetic conditions.
- Real-time geomagnetic integration: Ingests live Kp index data from NOAA Space Weather Prediction Center
- Multi-nucleus spin dynamics: Arbitrary nuclear spin configurations with heterogeneous hyperfine tensors
- Haberkorn recombination: Spin-selective singlet/triplet decay with configurable rate constants
- Coherence quantification: ℓ₁-norm coherence measure in Zeeman product basis
- Fisher information sensitivity: Binomial measurement model for magnetic field discriminability
- Phase classification: Automated regime detection (high-coherence → classical)
- Validation suite: Reproduces canonical RPM phenomenology (yield curves, anisotropy, RF disruption)
