Photoinduced supercurrents and Hall effect in 2D superconductors


  • Ivan Savenko Guangdong Technion – Israel Institute of Technology (GTIIT)


We consider a two-dimensional superconductor with a built-in supercurrent, exposed to circularly-polarized external electromagnetic field with the frequency of the order of the superconducting gap. In the system, there emerges an electric current due to optical transitions of the quasiparticles across the gap. Its direction is transverse to the initial supercurrent. This effect is second-order with respect to the external electromagnetic field amplitude. Thus, we propose a photoinduced Hall effect for the Cooper pairs and build a microscopic theory of the effect in the case of weak disorder.

Ivan Savenko is an Associate Professor at the Guangdong Technion – Israel Institute of Technology (GTIIT) in Shantou, China. His topics of interest are light-matter interaction in 2D Dirac materials, hybrid Bose-Fermi systems, and mesoscopic superconductivity. He received his Ph.D. in Physics in 2013 at the University of Iceland in Reykjavik, Iceland. The thesis was devoted to strong light-matter coupling in systems of different dimensionality. From 2013 until 2016, he worked as a postdoctoral researcher at Aalto University, Finland, before he moved to South Korea to take the position of an Assistant Professor and then, Associate Professor at the University of Science and Technology (UST) and a Junior Research Team Leader at the Center for Theoretical Physics of Complex Systems, Institute for Basic Science (IBS) in Daejeon. He also has experience working in Singapore, Brazil, Russia and Australia.
