Facts about the Niels Bohr Institute and its research

The Niels Bohr Institute (NBI) is a part of the Niels Bohr Institute for Astronomy, Physics and Geophysics, University of Copenhagen, and shares premises in the city with the Nordic Institute for Theoretical Physics (Nordita), which has programs in condensed matter and astrophysics in addition to the subjects listed below. Experimental activities take place at NBI (quantum optics and biophysics/complex systems), as well as at CERN, Brookhaven, DESY and other facilities in Europe and overseas.

The NBI has a long tradition of international collaboration and is a meeting ground for scientists from all over the world. Short-term visitors at the NBI number more than 150 per year, not including participants in the many symposia, workshops, and schools arranged each year. As a result, the NBI has the infrastructure needed to care for many foreign visitors and has a network of international contacts with the nearly 2000 physicists who have spent longer periods at the NBI and Nordita. The scientific staff at the NBI now comprises 27 permanent scientists, about 25 temporary scientists including long-term visitors, and for the present 16 Ph.D. students.

We can offer guidance to postdoctoral fellows in an inspiring scientific environment with emphasis on the valuable cross-fertilization between the many subfields of physics which are actively pursued here. Key words for the main topics of current NBI research activity are listed below (see also http://www.nbi.dk):

Theoretical Particle Physics and Field Theory

Non-perturbative string theory and quantum gravity; M-theory, AdS/CFT, and non-commutative geometry; non-perturbative physics within the standard model; particle cosmology; origin of gauge symmetries of the standard model.

Experimental Particle Physics

Final analysis of LEP data including (ALEPH, CERN); QCD-physics and charmonium suppression (HERA-B, DESY); B Bbar oscillations, CP violation in B-meson decays. Higgs-, SUSY- and searches for extra dimensions, trigger electronics and software also for the GRID (ATLAS, CERN).

Theoretical Nuclear Physics

Micro- and macroscopic description of nuclear structure and reactions; quantum theory of small systems; mechanisms of nucleus-nucleus collisions; nucleonic degrees of freedom at intermediate energy; phase structure of nuclear matter under extreme conditions.

Experimental Nuclear and Heavy Ion Physics

Rapidly rotating nuclei; multidetector gamma-spectroscopy (GASP, Exogam, Gammasphere); stable and radioactive beams; exotic deformation and extreme isospin; ultra relativistic heavy ion physics (RHIC [BRAHMS] and LHC [ALICE]); nuclear matter at extreme energy densities; the hadron gas to quark gluon plasma transition; coalescence; Bose-Einstein interferometry; hadron and antihydron abundances.

Physics of Nonlinear, Complex and Biological Systems (theory and experiment)

Dynamical systems - dissipative and Hamiltonian chaos; quantum chaos; pattern formation, turbulence, spatio-temporal chaos, hydrodynamic instabilities; dynamical chaos and foundations of statistical mechanics; neural systems; self-organized systems; protein folding; granular flow; sonoluminescence; single molecule manipulations; instabilities in blood vessels; gene reculation-immune systems; evolution; models for finance.

Experimental Quantum Optics

Danish National Research Foundation Center for Quantum Optics (QUANTOP) at NBI, generation of entangled states of atoms and photons, quantum teleportation, quantum memory, light-atoms quantum interface, cold and trapped atoms, Bose-Einstein condensation.
