DESCRIPTION:Speakers: Nils Paar (University of Zagreb)\n\nAbstract:\nUnder
 standing nuclear properties and excitation modes under stellar conditions 
 is essential for modeling astrophysical processes in extreme astrophysical
  environments such as core-collapse supernovae and neutron star mergers\, 
 as well as in the underlying nucleosynthesis. The focus of on-going invest
 igations in nuclear theory is on the microscopic description of nuclear ex
 citations and their impact on weak and electromagnetic reaction rates in h
 ot and dense environments. Special emphasis is placed on spin–isospin mo
 des\, which play a decisive role in β-decay\, and electron capture at fin
 ite temperature. In addition\, low-energy transitions such as the pygmy di
 pole strengh have important contributions in neutron rich nuclei\, in part
 icular in photoneutron and photoabsorption reactions in stellar environmen
 ts. Finitetemperature eDects have recently been investigated especially in
  global nuclear properties\, nuclear response functions\, thermal unblocki
 ng of transitions\, and in (n\,gamma) nuclear reaction rates. By combining
  self-consistent relativistic energydensity functional theory with quasipa
 rticle random-phase approximation\, these studies allow a unified descript
 ion of nuclear structure and reactions relevant for stellar evolution and 
 synthesis of chemical elements in extremely hot environments in the univer
 se.\nBiography:\nProf. Nils Paar is a full professor of physics at the Uni
 versity of Zagreb\, Faculty of Science\, Croatia. He has served as Head of
  the Division for Theoretical Physics\, Head of the Department of Physics 
 at the Faculty of Science\, and as a member of the Senate of the Universit
 y of Zagreb. He obtained his Ph.D. in theoretical nuclear physics from Tec
 hnical University Munich in 2003 under the supervision of Prof. Peter Ring
 . Following a postdoctoral position at Technical University Darmstadt unti
 l 2006\, he joined the University of Zagreb Faculty of Science\, where he 
 is currently serving as a full professor. From 2014-2015 he was a Marie Cu
 rie research fellow at Universitaet Basel\, Switzerland. His research acti
 vities in exotic nuclear structure and dynamics\, astrophysically relevant
  weak-interaction processes and neutrino-induced reactions\, resulted in p
 ublication record comprising over 150 papers in international scientific j
 ournals and conference proceedings\, with over 5000 citations (WoS). Over 
 the course of his career\, he has overseen and mentored a multitude of sch
 olars\, guiding them through Master's\, Ph.D.\, and postdoctoral research 
 programs\, in addition to hosting international guests. He has actively pa
 rticipated in international conferences and workshops\, delivering more th
 an 80 talks\, including 44 invited presentations.\nHost: Prof. Yifei Niu\n
