The lecture entitled "High magnetic field compatible InSb nanowire hybrids" will be given by dr Grzegorz Mazur (QuTech, TU Delft, Delft, The Netherlands).


Semiconductor nanowires coupled to superconductors are promising candidates for realizing topological superconductivity in solid state systems. A limiting factor for InSb/Al based hybrid nanowire systems is a rather narrow parameter space defined by small superconducting gap and resulting modest magnetic field resilience. I will discuss opportunities for increasing field compatibility of InSb/Al hybrids by lifting the Pauli limit within the superconducting segment. In a 3-terminal geometry, we explore the induced superconductivity in the bulk of hybrid nanowire by means of non-local conductance measurements, while simultaneously probing local density of states at the nanowire ends. The combination of high-mobility semiconducting wires and a field-resilient superconductor allows us to probe properties of InSb/Al hybrids in the presence of high Zeeman field, a potentially interesting region for realizing topological superconducting phase.
