      Coulomb repulsive correlation in A3B5 semiconductor quantum dots in the presence of a magnetic field 

      Avetisyan, A. A.; Djotyan, Anahit P.; Moulopoulos, Konstantinos (2006)
      The ground state total and correlation energies of a negative ion-electron and electron-electron systems in a parabolic QD with standard dispersion law are theoretically investigated in an external magnetic field by a ...

      Study of the a0(980) on the lattice 

      Wagner, M.; Abdel-Rehim, A.; Alexandrou, Constantia; Gravina, M.; Koutsou, Giannis; Brida, M. D.; Scorzato, L.; Urbach, C. (Proceedings of Science (PoS), 2013)
      We present lattice results for the a0(980) state using a variational approach with a variety of creation operators: quark- Antiquark, mesonic molecule, diquark- Antidiquark as well as two-meson type. Focus is put on recent ...
