Job Description

Job Title: Research assistant and extracurricular PhD student

Job Summary: The winning candidate will work as a ¾ full time research assistant at the International Centre for Interfacing Magnetism and Superconductivity with Topological Matter – MagTop of the Institute of Physics of the Polish Academy of Sciences and prepare a doctoral thesis in the extramural mode, attending lectures at the Warsaw-4-PhD Doctoral School. The job is related to the study of quantum transport in topological superconductors (theory).

Job Description: Background: It is well established that topological effects are well-suited for metrology applications due to the high-accuracy of quantisation of physical observables and the robustness of the response so that the variations between devices are small. The quantum Hall effect has been widely used as a resistance standard and ac Josephson effect as a voltage standard. By exploring the magnetisation dynamics in ferromagnetic-semiconducting-superconducting hybrids, we have recently unraveled a novel quantised effect—the spin-pumping—which characterises the topology of the system similarly to the conductance in static cases [https://doi.org/10.1103/PhysRevB.103.205410, https://doi.org/10.1103/PhysRevLett.130.237002, https://patents.google.com/patent/EP3975275A1/en]. The study concerns quantum (spin) transport in topological superconductors harbouring Majorana zero modes (MZMs).

Aim: To extend our investigations to multi-band nanowires, and eventually to two-dimensional (2D) setups, and determine whether more complex devices still exhibit the quantised spin pumping effect. Initial calculations point towards a positive answer, but more work (in particular on InAs semiconducting slabs covered with 2D superconductors and ferromagnets, such Nb and EuS, respectively) is required in order to enhance these findings towards practical applications. Among those are the possibility to inject deterministically MZMs from the chiral edges into the insulating bulk by appropriately chosen magnetisation pulses. The PhD will employ both analytical and numerical tools in order to tackle such dynamical situations. The first will based on the scattering matrix theory of adiabatic pumping for establishing the scalings, while we will use the KWANT code for simulating real experimental situations.

Requirements:

A Master’s degree in Physics or in related fields, such as e.g. condensed matter physics (preferably theory) and, is required (or an equivalent that qualifies one for PhD studies in physics in the country of issue),
Prior experience of working with Python and/or KWANT is highly desirable, but not required
Very good knowledge of English is required.

Main research field: Physics

Sub Research Field: Condensed matter theory, quantum transport

Career Stage: Early stage researcher or 0-4 yrs. (Post-graduate)

Research Profile (details): First Stage Researcher (R1)

Type of Contract: Initial employment for a fixed term of 24 months, including a 3-month probationary period. Prolongation of employment for a further 24 months will be based on performance and successful completion of a mid-term evaluation performed at a level analogous to that in the PhD school.

Status: Part -time employee hired at ¾ of full-time contract

Salary: The person will be employed as a research assistant in a ¾ full time position for a period of maximum 4 years (with all employee benefits and an additional medical insurance package) with a gross salary of PLN 7 275 per month, which is approximately PLN 5 500 net/month. The MagTop project (FENG.02.01-IP.05-0028/23) is implemented as part of the MAB FENG action of the Foundation for Polish Science co-financed by the European Union from the 2nd Priority funds of the Programme European Funds for Smart Economy 2021-2027 (FENG).
