Szabolcs Csonka is an associate professor of the Department of Physics, BME and the head of the MTA-BME Nanoelectronics Momentum research group. His research group focuses on the development and investigation of various nanocircuits, which are dominated by quantum mechanical phenomena. Circuits are developed from different nanostructures, like 1D semiconductor nanowires, 2D van der Waals structures or giant Rashba spin-orbit materials. The nanostructures are integrated into hybrid nanocircuits, where superconductor and/or ferromagnetic correlations are present. The circuits are investigated at ultra-low temperature in magnetic field with dc and microwave excitations. He fabricated the first Cooper-pair splitter device, which allows to produce spatially separated spin entangled electron pairs. Furthermore he has several highly acknowledged results on the spectra of superconductor-artificial atom hybrids, which could lead to building blocks of novel topological quantum computers. He has been the coordinator of EU research networks (QuantERA), received ERC Starting grant (2010), Talentum award (2012), Zoltán Gyulai prize (2016), MTA Physics prize (2020).
