Topic 1: Finite nuclei and nuclear matter in the Ouark-Meson-Coupling Model(QMC) 

Time: 4 p.m. July 2th Thursday

Venue: Meeting room, on 6th floor,Technology building, IMP




  The fundamental problem of low energy nuclear structure is the understanding the change of the free nucleon-nucleon force in the nuclear medium. Commonly used forces of the Skyrme or Gogny type, with their empirical medium density dependence, cannot be determined uniquely. Hundreds of such forces have been constructed, fitting their numerous correlated parameters to selected experimental data. We report a single, four-parameter form of the density dependent effective nucleon-nucleon force based on modification of the nucleon structure in-medium on the quark level, which represents a new paradigm for nuclear physics. The model yields results for the ground-state binding energies, electromagnetic properties and shapes of even-even nuclei, from the lightest to superheavy, in agreement with experiment within less than a fraction of a percent.     

  One of the important constraints on any force is the requirement that it works equally well in nuclear matter as in finite nuclei and can give a realistic description of compact objects such as cold neutron stars. We show that the QMC model predicts masses of cold neutron stars, with cores containing the full baryon octet, in agreement with observation.     

  Further development and application of the QMC model in other areas, such as hypernuclei and heavy ion collisions will be outlined. 






  Short CV - J.R. Stone    

  Jirina Rikovska Stone is currently a visiting researcher at the Department of Physics, Oxford University, UK, and an Adjunct Professor of Physics at the Department of Physics and Astronomy at the University of Tennessee , USA .    

  She obtained her PhD at the Charles University of Prague, Czech Republic and worked at different institutions, including the Technical University of Prague, the Institute of Nuclear Physics of the Czech Academy of Sciences in Rez near Prague, Czech Republic and the Joint Institute for Nuclear Research, Dubna, Russia.      

  She has extensive teaching experience both at undergraduate and graduate level and has supervised more than 15 PhD students both in Oxford and Tennessee.   

  Her research interests range from theoretical nuclear physics and astrophysics to experimental investigation of nuclear magnetism and low-energy nuclear structure.     

  In 1984 she moved to Oxford University in the UK and worked there until her retirement.  She moved to the United States in 2005 and joined the University of Tennessee to continue with her research. She maintains world-wide collaborations with researchers in the United Kingdom, Germany, Australia and Japan.   

  She is an author of more than 150 papers in refereed journals and numerous contributions to conference proceedings and reports. She is a frequent invited speaker at conferences, workshops and schools.  Her other activities involve refereeing of papers for journals of the American Physical Society, Nuclear Physics A, Physical Letters B, The Astrophysics Journal, Journal of  Physics G and others.
