2.5-dimensional superconducting heterostructures. 01/06/2024 - 30/11/2024

Abstract

Ever since the discovery of high-temperature superconductivity in late 1980's, cuprate superconductors have attracted immense attention in the literature. One of such materials, Bi2Sr2CaCu2O8+δ (BSCCO) was shown to sustain its superconducting state down to its 2D limit of a single monolayer, which then can be used to design functional 2.5-dimensional heterostructures. For example, having d-wave pairing symmetry, a twisted bilayer of BSCCO monolayers displays topological superconductivity with broken time reversal symmetry for some particular values of the twist angle, which holds promise for the construction of novel superconducting devices for applications in advanced communication systems and quantum computing. Further way from the 2D limit, BSCCO heterostructures can be constructed to exhibit a superconducting diode effect up to a high critical temperature, enabling their use in other fundamental superconducting electronics. The overarching theme of this joint doctorate is to provide multiscale modeling of selected superconducting electronic devices, where latter described BSCCO systems under the influence of applied magnetic field and electrical current are the main selected example for the 6-month research stay of the student in Antwerp. Owing to the recently established collaboration in China and India, we gained access to the experimental data on 2.5D BSCCO systems that will benefit from numerically tailored properties in this project, geared towards the optimal design of selected electronic devices.
