recommendations! Published in 2019 at "Journal of Superconductivity and Novel Magnetism"

DOI: 10.1007/s10948-019-5112-6

Abstract: In this study, we carried out the analysis of the thermal fluctuations on Josephson junction (JJ) dynamics with unconventional current-phase relation (CPR). We analyzed two cases of CPR: the anharmonic term case and the case… read more here.

recommendations! Published in 2019 at "Nature"

DOI: 10.1038/s41586-019-1148-9

Abstract: Topological superconductors can support localized Majorana states at their boundaries1–5. These quasi-particle excitations obey non-Abelian statistics that can be used to encode and manipulate quantum information in a topologically protected manner6,7. Although signatures of Majorana… read more here.
