Tomohiro Yokoyama

has left us for further post-doc career in Japan. He stayed with me as a post-doc – eventually, a JSPS fellow, from 6.4.2014. We have worked on Andreev bound states in superconducting heterostructures, with and without spin-orbit interaction. We still have to finish a (very big) paper. Thank you, Tomohiro, with you I did the stuff I wouldn’t do otherwise. Best luck with your new job!

Silence and ERC Advanced Grant proposal

I didn’t write much to the blog for almost a couple of months. An excuse for this is I’ve been busy preparing an important grant proposal. Not that it really took every minute of my working time – yet for me it is psychologically difficult to prepare proposals, and any unrelated activity eventually gives a feeling of guilt – whatever irrational it may be.

Anyway, I’m almost done and will submit the proposal soon. It is in development of the recent ideas about topological properties of superconducting junctions. Below is the title and the abstract.

Higher-dimensional topological solids realized with multi-terminal superconducting junctions (HITSUPERJU)

Recently I revealed a deep operational analogy between an exotic material and an electronic device, i.e. between a 3-dimensional topological solid and a 4-terminal superconducting junction. Specifically, the 3d Weyl singularities revealed in the energy spectrum of this quantum device give rise to quantized trans-conductance in two leads that is typical for 2-dimensional topological Quantum Hall materials. The quantized value can be tuned with the third control phase.

I propose to capitalize on this breakthrough by realizing artificial n-dimensional (topological) solid materials by (n+1)-terminal superconducting junctions. This seemed to be fundamentally forbidden so far. In particular, in the framework of one research direction I will address the realization of higher Chern numbers. The edges and interfaces are important in topological solids, they need to be structured. For the artificial topological materials made with multi-terminal superconducting junctions such structuring is impossible in geometric coordinate space. However, the fact that the charge and superconducting phase are quantum-conjugated quantities provide the unique possibility for the structuring in multi-dimensional charge space that I will access in the framework of another direction. These two research directions will be supplemented by a more technical effort devoted to computational (quantum) dynamics of multi-terminal superconducting junctions.

The proposed way to “conquer” higher dimensions for condensed matter physics is of clear fundamental importance. Exciting applications are at the horizon, too. The exotic quantum states under consideration can be topologically protected and thus useful for quantum information processing. Quantized trans-resistance as well as other topological invariants may be important in metrology. More generally, the research proposed will boost the whole field of electronic devices wherever topology guarantees the discrete stability of device characteristics.
