DESCRIPTION:Speakers: Stefan Typel (Technical University of Darmstadt)\n\n
 Abstract:Energy density functionals (EDFs) have been used extensively with
  great success to calculate properties of nuclei and to predict the equati
 on of state (EOS) of dense nuclear matter. Besides nonrelativistic EDFs\, 
 mostly of the Skyrme type\, relativistic EDFs of different types are in wi
 despread use. In these latter approaches\, the effective in-medium interac
 tion is described by an exchange of mesons between nucleons. In most cases
 \, only minimal meson-nucleon couplings are considered. The effects of add
 itional tensor couplings were rarely investigated. In this talk\, a new re
 lativistic EDF with tensor couplings and density dependent minimal meson-n
 ucleon couplings will be presented. The parameters of the model are determ
 ined using a carefully selected set of experimental data with realistic un
 certainties that are determined self-consistently. Predictions for various
  nuclear observables and properties of compact stars will be discussed.Bio
 graphy:Stefan Typel is a senior research scientist and head of the IT grou
 p at the Institute for Nuclear Physics\, Technical University of Darmstadt
  (Germany). He received his Ph.D. from Münster University in 1994\, after
  which he held postdoctoral positions at Université Libre des Bruxelles (
 Belgium) as Marie Curie Research Fellow\; Ludwigs-Maximilians University\,
  Munich (Germany)\; NSCL\, Michigan State University\, East Lansing (MI\, 
 USA)\; GSI\, Darmstadt (Germany)\; GANIL\, Caen (France)\; Excellence Clus
 ter Universe\, Technical University\, Munich (Germany)\; Helmholtz Interna
 tional Center for FAIR\, Darmstadt (Germany)\; and Nuclear Astrophysics Vi
 rtual Institute\, GSI\, Darmstadt (Germany). Since 2016 he works as theore
 tical physicist at the Institute for Nuclear Physics\, TU Darmstadt (Germa
 ny) and he is member of the Collaborative Research Center (SFB) 1245.Stefa
 n Typel's work focuses on the theory of direct reactions\, e.g.\, nucleon 
 and cluster knockout reactions and indirect methods for nuclear astrophysi
 cs (Coulomb dissociation\, Trojan-horse method)\, and on relativistic ener
 gy density functionals for nuclei and nuclear matter\, in particular the e
 quation of state with correlations and clusters for neutron stars and simu
 lations of core-collapse supernovae. To date he has published more than 11
 0 research papers in journals including Science\, Nature Astronomy\, Physi
 cal Review Letters\, and Reviews of Modern Physics. Host: Prof. Liewen Ch
