- 13.12.2018 - NEST Seminar - Pauli VirtanenDate and Time: Thursday December 13, 2018 - 15.00 Venue: NEST Seminar Room Speaker: Pauli VIrtanen Title: Majorana bound states in hybrid 2D Josephson junctions with ferromagnetic insulators Abstract:We consider a Josephson junction consisting of superconductor/ferromagnetic insulator (S/FI) bilayers as electrodes which proximizes a nearby 2D electron gas. We discuss the interplay between the superconducting and magnetic proximity effects and the conditions under which the structure undergoes topological transitions. We discuss a transfer matrix approach to the 2D bound state problem that reduces the problem to an effective 1D Hamiltonian, allowing straightforward study the structure. We consider a narrow channel coupled with multiple ferromagnetic superconducting fingers, and discuss how the bound states can be spatially controlled by tuning the superconducting phases. [1] Phys. Rev. B 98, 020501R (2018) Host: Alessandro Braggio alessandro.braggio@nano.cnr.it.
