Figure 5
Minimal model. (a) Schematic illustration. A single-particle system is incoherently coupled to an auxiliary state |s〉, which induces a current with driving f. (b) Eigenstructure. The depicted energies εν correspond to K = 20 and δ = 2. The gap between the most energetic eigenstate |Ψ〉 (red dot), preferentially populated at maximal driving and zero dephasing (see Eq. (S1) of the SI), and the conducting band, is of \({\mathscr{O}}(\delta )\).
