The Wigner Research Centre for Physics was founded on 1 January 2012 by the merging of two former research institutes of the Hungarian Academy of Sciences: the Research Institute for Particle and Nuclear Physics, and the Research Institute for Solid State Physics and Optics. In our Research Centre there are 40 research groups. Their research interests cover diverse topics ranging from particle physics to space physics, and from theoretical physics to applied research. Wigner Research Centre for Physics of the H.A.S. deals with the following main research areas as research activities: Experimental and theoretical particle physics, nuclear physics, general theory of relativity and gravitation, fusion plasma physics, space physics, nuclear materials science, mainly in the Institute for Particle and Nuclear Physics; Experimental and theoretical solid state physics, statistical physics, nuclear physics, optics, and materials sciences mainly in the Institute for Solid State Physics and Optics.
