Descripción del proyecto
Suceden cosas extrañas cuando los aislantes topológicos se acercan a los superconductores
Los materiales topológicos exhiben comportamientos poco habituales como resultado de su resistencia al cambio o a la perturbación cuando se trata de ciertas características. Estos comportamientos se conocen como estados de la materia protegidos topológicamente y se aprecian en cada vez más y más materiales. Los superconductores topológicos y los aislantes topológicos se encuentran entre ellos, y son posibles sustratos para los ordenadores cuánticos y la electrónica cuántica. El proyecto DEPTH, con el apoyo de las Acciones Marie Skłodowska-Curie, está investigando la creación un nuevo tipo de dispositivo de estado sólido basado en superconductores topológicos. Para lograrlo, se utilizarán los aislantes topológicos bidimensionales recientemente descubiertos a fin de inducir canales superconductores unidimensionales protegidos topológicamente mediante la proximidad a un superconductor.
Objetivo
Topological superconducting matter has attracted much interest in the recent years, carrying the long-term vision of next generation of quantum electronic devices. Its potential stems from fundamental underlying properties, specifically the presence of topologically protected currents or low energy modes such as Majorana fermions.
This project aims at exploring a novel type of topological superconducting matter solid-state device (Topological Josephson Junctions) resulting from coupling a high temperature d-wave superconductor and recently discovered two-dimensional Topological Insulators (2DTIs).
The project will rely on 2DTIs made from transition metal dichalcogenides. These Dirac materials support 1D channels at their boundaries which are protected from backscattering by time reversal symmetry. While in proximity with a superconductor, superconductivity can be induced in the Quantum Spin Hall states, resulting in topologically protected superconducting 1D channels. If the superconductor is a high temperature d-wave, new devices can be envisioned based on the specific nodal pairing symmetries coupling with the 2DTI. This project aims at exploring the potential of such new devices for quantum electronics, leading the way to the realization of topological electronic devices and fault-tolerant topological quantum information applications.
This reintegration project relies on the unique complementary competences of the researcher on TIs (imported from his US post-doc) and of the host institution on high temperature d-wave superconductors and 2D materials. The acquired knowledge and IP training by the industrial partner will give the researcher a unique profile in the European research environment. This will give the researcher a strong edge to seek for a position at the interface between academia and industry.
