Wigner Research Centre for Physics

The Wigner Research Centre for Physics belongs to the Hungarian Academy of Sciences. The centre is situated at a research campus separated about 10 kilometers from the downtown of Budapest, amidst the gentle hills and woodlands of Buda. The Wigner RCP incorporates the Institute for Solid State Physics and Optics which is devoted to conducting basic theoretical and experimental researches in the fields of material structure analysis, quantum correlated systems, quantum optics, complex fluids.  The experimental research rests on a broad variety of techniques including x-ray diffraction, NMR, Mössbauer and optical spectroscopy. Neutron scattering experiments can be locally performed at the Budapest Neutron Centre,  a large scale on-campus research facility. Our application oriented research and development program focuses on optical thin films, applications of laser technology, growing of optical crystals, and metallurgy.  Our staff of 196 includes 130 scientists among which there are about 30 PhD students. RISSPO has been given the title “Centre of Excellence” between 2000-2004, and organized several international schools in the frame of this programme.

The Quantum Optics Department is committed to theoretical research in quantum optics and quantum information processing. It consists of 6 permanent theorists,  about 5 postdoctoral fellows and 5-10 students. The group led by Peter Domokos focusses on cavity QED, a field being closely related to quantum field theory (line shifts, vacuum effects, quantum states of radiation), statistical physics (open systems, irreversibility, Bose condensates), and solid state physics (interacting many-body systems, lattice models).  The common denominator of the various research directions throughout the years since the mid nineties can be defined as the study of the light-matter interaction at a microscopic level. The group routinely resorts to a broad spectrum of different methods and approaches including rigorous algebraic calculations, analytical descriptions of interacting quantum systems, and numerical simulations of many-body open systems. Many of the projects are pursued in international collaborations.

Within the network, this partner provides for a theoretical background for the manipulation, laser cooling and trapping of particles  strongly coupled to the radiation field in a cavity. New type of cavity QED systems will be theoretically explored.
