I. Majorana fermions in transport through correlated nanosystems

21 Jan 2019 - 20 Jan 2022

The research objective of this project are the Majorana quasiparticles and their interplay with the strongly correlated low-dimensional systems. In particular, there will analyzed hybrid nanostructures composed of zero-dimensional objects e.g. single or multiple quantum dots coupled to one-dimensional topological superconductors, hosting the Majorana quasiparticles. The main aim is to develop theoretical understanding of unique signatures resulting from the Majorana quasiparticles and the strong electron correlations, predicting experimentally observable transport properties. Research tasks cover: (i) investigation of the transport properties of the correlated double quantum dots side-coupled to the Majorana wire, (ii) determination of cross-correlations between the quantum dots transmitted via the topologically superconducting nanowire, (iii) analysis of the interplay between the Majorana quasiparticles and correlations for the quantum dot in the Kondo regime, investigation of the polarized quasiparticles in hybrid structures with the correlated quantum dots.

II. Bound states in superconductors and interfaces

29 Jun 2018 - 28 Jun 2021

Recent theoretical and experimental activities focus on studying unique phenomena of the novel materials and nanostructures, in which the proximity-induced superconducting state reveals topological and quantum properties without analogy to any bulk system. Technological development opened possibilities to achieve and probe such exotic superconductivity e.g. in atoms, molecules, carbon nanotubes, nanowires and other ultra-small objects. Main subject of this research project are the Andreev/Shiba quasiparticle states, in particular: (i) role of the bound in-gap states in multiterminal structures, focusing on the non-local charge, spin and energy transport properties, (i) dynamical effects (quantum quench, transient phenomena, shot-noise, waiting time distribution), (ii) quantum phase transitions due to the subtle interplay betwee electron pairing and correlations, and analysis of their feasible observability controlled by the electrostatic/magnetic means, (iii) investigation of the spin-polarized Majorana quasiparticles in the topological superconductors, (iv) charge/spin teleportation driven by the crossed Andreev scattering via the Majorana quasiparticles, (v) role of the spin-orbit interactions in nanoscopic superconductors.
