Current-phase relation of a short multi-mode Bi2Se3 topological insulator nanoribbon Josephson junction with ballistic transport modes
Ananthu P. Surendran, Domenico Montemurro, Gunta Kunakova +8
We used the asymmetric superconducting quantum interference device (SQUID) technique to extract the current phase relation (CPR) of a Josephson junction with a 3D-topological insul…

Xiangyu Song, Soorya Suresh-Babu, Yang Bai +6
It is a well known phenomenon in optics that spectroscopic resolution of a diffraction grating is much better compared to an interference device having just two slits, as in the Yo…
