We present an improved Wentzel-Kramers-Brillouin (WKB) calculation of tunnel splitting in one dimensional asymmetric double well potentials. We show that the tunnel splitting in general can have linear dependence on the bias energy, beside the well-known quadratic dependence. We demonstrate that the linear correction is greater than previously thought.

  1. Quantum Tunneling-induced Hybridization and Coherent Dynamics of Jackiw-Rebbi Zero Modes in a Modified Su-Schrieffer-Heeger Chain

    cond-mat.str-el 2026-07 unverdicted novelty 5.0 of 10

    A modified SSH model supports a pair of Jackiw-Rebbi zero modes that hybridize via tunneling, enabling coherent oscillations whose period is set by the hybridization gap.
