    • Coupling of electrons to the electromagnetic field in a localized basis 
      Allen, Roland E. (American Physical Society, 2008)
      A simple formula is obtained for coupling electrons in a complex system to the electromagnetic field. It includes the effect of intra-atomic excitations and nuclear motion, and can be applied in, e.g., first-principles-based ...
    • Giant monopole resonance strength in Ca-40 
      Youngblood, David H.; Lui, YW; Clark, HL. (American Physical Society, 1997)
      The giant resonance region in Ca-40 was studied with inelastic scattering of 240 MeV alpha particles at small angles including 0 degrees. A peak at E-x = 17.5 +/- 0.4 MeV with Gamma = 4.95 +/- 0.25 MeV was found to contain ...
    • Hadronic modes and quark properties in the quark-gluon plasma 
      Mannarelli, M.; Rapp, Ralf. (American Physical Society, 2005)
      Based on interaction potentials between a heavy quark and antiquark as extracted from recent QCD lattice calculations, we set up a Brueckner-type many-body scheme to study the properties of light (anti-) quarks in a ...
    • Quarkonia and heavy-quark relaxation times in the quark-gluon plasma 
      Riek, F.; Rapp, Ralf. (American Physical Society, 2010)
      A thermodynamic T-matrix approach for elastic two-body interactions is employed to calculate spectral functions of open and hidden heavy-quark systems in the quark-gluon plasma. This enables the evaluation of quarkonium ...
