  • Title: The Evolution of Quantum Hadrodynamics (QHD), and its Applications to Neutron Stars
  • Abstract:
    The quantum hadrodynamics (QHD) is a relativistic field theory for nuclear physics with baryons and mesons, which has been applied to vast phenomena from nuclear physics to astrophysics. It has opened an active research field of nuclear astrophysics, and many researchers have contributed to analyses of nuclear and astrophysical phenomena by employing method of QHD (neutron stars, baryon-quark phase transition, many-body theory of nuclear matter, etc.). The philosophy and motivation for relativistic field theories of nuclear phenomena have evolved over the last quarter of 20th century in response to success, limitation and criticism (see, chapter 3 in Neutron Stars: the aspect of high density matter, equations of state and observables, H.Uechi, S.T.Uechi and B.D.Serot, Nova Science Pub. (2012)). The speaker reviews the evolution of QHD in terms of many-body theory of nuclear matter and applications to neutron star calculations.
  • Biography:
    Hiroshi Uechi, PhD in nuclear physics. He obtained his doctoral degree in nuclear physics (theoretical nuclear physics) from Indiana University, USA, under the guidance of Professor Brian D. Serot who founded the nuclear field theory, quantum hadrodynamics (QHD) with Professor John D. Walecka. Currently, he is a professor at Osaka Gakuin University, and has been working on nuclear many-body theory and nuclear astrophysics. He has been investigating self-consistent QHD approximations in terms of Landau’s Fermi-liquid theory and density functional theory (DFT), while applying QHD nonlinear effective models and approximations to neutron star calculations. He revealed that nonlinear mean-field approximation method for nuclear matter is equivalent to Hartree approximation and suggested the importance of self-consistent approximation method beyond mean-field approximations.
