Quantum Transport group at the Autonomous University of Madrid is looking for a highly motivated student to join them. The PhD project will take place within the framework of the ERC Starting Grant project “A bottom up topological superconductor based on quantum dot arrays”, directed by Dr. Eduardo Lee and focused on hybrid superconductor-semiconductor nanostructures.
In recent years, hybrid superconductor-semiconductor nanostructures have attracted considerable interest as a platform for realizing a topological superconductor, a new state of matter associated with exotic boundary states known as Majorana modes. Of particular interest, these states hold promise for applications in topological quantum computation, where information is protected against local sources of decoherence. Despite the great experimental advances towards realizing Majorana modes, a fully conclusive demonstration is still missing. In this project, we will investigate a novel methodology to engineer a topological superconductor: to controllably assemble it using quantum dot arrays. To this end, we will study in detail the “trivial” sub-gap (Andreev) states of quantum dots coupled to “ordinary” superconductors.
The experimental work will involve the nano-fabrication of hybrid superconductor-semiconductor quantum dot devices (using optical and e-beam lithography), and low temperature quantum transport experiments. Candidates should hold a master´s degree, preferably in physics or a closely related discipline. Prior experience in (experimental) condensed matter physics will be valued. The selected candidate will receive funding for 3 years (with possibility of extension).
For further information and to apply, please contact Eduardo J. H. Lee (eduardo.lee@uam.es). Applications should include a cover letter, CV, two recommendation letters and grade transcripts. The deadline is September 15th, 2019.
