Matrix Thermodynamic Uncertainty Relation for Non-Abelian Charge Transport
Analysis
Key Takeaways
- •Derives a matrix thermodynamic uncertainty relation (TUR) for non-Abelian charge transport.
- •Provides a lower bound on current precision based on entropy production.
- •The bound is fully nonlinear and saturable.
- •Valid for arbitrary current vectors.
- •Demonstrates near-saturation in numerical simulations.
“The paper proves a fully nonlinear, saturable lower bound valid for arbitrary current vectors Δq: D_bath ≥ B(Δq,V,V'), where the bound depends only on the transported-charge signal Δq and the pre/post collision covariance matrices V and V'.”
