Disorder induces a crossover from phase-averaging to mode-mixing regimes in domain wall transport of a second-order topological insulator, marked by a 0.5 e²/h plateau and two-step conductance fluctuations at 0.35 and 0.29 e²/h with corresponding Fano factors of 1/4 and 1/3.

Fermi seas with the same Euler characteristic χ_F possess distinct fine-grained topological structures captured by a new structural resolution factor, which topological superconductors inherit to produce anomalous gapless boundary states.
Dual dc bias on a Bloch transistor produces phase-locked Josephson-Bloch oscillations yielding dual Shapiro steps at I_B = 2e f_J and exact transconductance 1/R_Q.
Supervised ML trained on field- and bias-dependent conductance extracts the q-vector of arbitrary spin-spiral magnets in 2D moiré systems.
Rotated anisotropic Fermi surfaces generate a continuous, non-quantized transverse conductivity in 2D via broken mirror symmetry alone.
