Supervisor’s research interests

More than 10 years ago, it was discovered the intense reflection of low-energy neutrons from nano-dispersed media. Since then, the FLNP JINR has been studying the interaction of neutrons with diamond nanoparticle powders. At the moment, there are no worldwide analogues of the nanostructured reflectors of very cold neutrons created by us. The accumulated knowledge and collaborations with industrial partners allow us to move on to creating intensive sources of such neutrons. Their appearance will give a new pulse to both neutron studies of condensed matter and the study of fundamental interactions.

Research highlights

The planned research allows us to welcome candidates from different spheres: physicists, mathematicians, engineers, programmers, and so on. The estimated tasks include working together with ionizing radiation sources at mega-science installations with our colleagues from Institut Laue-Langevin (France), Heinz Maier-Leibnitz Zentrum (Germany), etc. The research is supported by national and international scientific grants, including the CREMLINplus grant of the European Commission under Horizon 2020.
