Abstract

In article number 2100124, Vasily S. Stolyarov and colleagues have observed unexpectedly fine (≈1 Oe) resonant oscillations of the critical Josephson current in the magnetic field in ballistic Nb-Bi2Te2.3Se0.7-Nb proximity junctions at temperatures below 500 mK. The peaked maxima of oscillations are attributed to the resonant transmission of quasiparticles through low-lying Andreev bound states forming at the superconductor-topological insulator interfaces owing to the p-wave component of the induced superconducting order.
