We report non-equilibrium quantum Hall transport in a bilayer graphene Corbino device. Strong DC bias generates diamond-shaped resistance features interpreted as driven spectral flow arrested by inelastic scattering, realizing a non-equilibrium analogue of renormalization-group flow parameterized by a bias-controlled coherence length.
