20.500.12556/RUL-167354 Artificial topological insulator realized in a two-terminal Josephson junction with Rashba spin-orbit interaction We study a two-terminal Josephson junction with conventional superconductors and a normal region with a Rashba spin-orbit interaction, characterized by two Aharonov-Casher (AC) fluxes. When the superconducting phase difference equals π, the Andreev subgap spectrum may host zero-energy Weyl singularities associated with a vanishing normal-state reflection eigenvalue. With one of the AC fluxes playing the role of a quasimomentum, the junction can be viewed as an artificial one-dimensional chiral topological insulator. Its topological phase can be tuned by crossing a Weyl singularity by means of varying the remaining AC flux. By associating an additional component of the quasimomentum with the superconducting phase difference, an artificial Chern insulator is realized. sondensed matter physics superconductors fizika kondenzirane snovi superprevodniki true false true Angleški jezik Slovenski jezik Članek v reviji 2025-02-17 13:46:12 2025-02-17 13:46:13 2025-02-18 03:55:43 0000-00-00 00:00:00 2025 0 0 Str. 013166-1-013166-6 iss. 1 Vol. 7 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 538.9 2643-1564 10.1103/PhysRevResearch.7.013166 226373123 PhysRevResearch.7.013166.pdf PhysRevResearch.7.013166.pdf 1 1CDC568B37076FB5EF2608E2051C6DC7 b0377ea3480e53c784e737277ef47b0626d56a880c8eb92849560802d6c71f7e cd273da3-ed2c-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=199722 https://journals.aps.org/prresearch/abstract/10.1103/PhysRevResearch.7.013166 0 dfce1d91-ed2c-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=199724 Fakulteta za matematiko in fiziko 0 0 0
