Bound States of Fermions in External and Self-Consistent Fields

  title={Bound States of Fermions in External and Self-Consistent Fields},
  author={Johann Rafelski},
The properties of spin-1/2 fields in strong external potentials are investigated, motivated by the question ‘What happens to the electron orbitals as the charge of the nucleus is increased without bounds?’ Interest in this problem and in the related Klein paradox extends back nearly to the beginnings of relativistic quantum mechanics. However, the correct interpretation of the theory for overcritical potentials, where the parts of the complete set of sing le-particle solutions associated with…

Overcritical Potential for Bose Fields

For a discussion of overcritical behaviour of bosons a full understanding of the single particle energy spectrum is required. The solutions of the Klein-Gordon equation can exhibit two distinct types



The quantum theory of the electron

The new quantum mechanics, when applied to the problem of the structure of the atom with point-charge electrons, does not give results in agreement with experiment. The discrepancies consist of

Heavy Quarks and Strong Binding: A Field Theory of Hadron Structure

We investigate in canonical field theory the possibility that quarks may exist in isolation as very heavy particles, M quark >> 1 GeV, yet form strongly bound hadronic states, Mhadron N 1 GeV. In a

Precise Values for Critical Fields in Quantum Electrodynamics

A careful investigation of different corrections to binding energies of electrons in almost critical fields is performed. We investigate quantitatively the influence of the nuclear charge parameters,

A New Extended Model of Hadrons

We propose that a strongly interacting particle is a finite region of space to which fields are confined. The confinement is accomplished in a Lorentz-invariant way by endowing the finite region with

Vector coupling and bound states of fermions in three space dimensions

The behavior of fermions interacting via vector gluons in the strong-coupling limit is investigated. A suitable coupling betweeen the Dirac and the vector-gluon field gives rise to bound-state

Electron wave functions in over-critical electrostatic potentials

SummaryThe mathematical properties of the solutions of the Dirac equation in over-critical external potentials are investigated. The 1/r Coulomb potential is treated as the limitR → 0 of cut-off

Virial theorem and stability of localized solutions of relativistic classical interacting fields

The properties of classical meson fields interacting with the Dirac field are considered in more detail analytically. We obtain a virial relation between the kinematic and potential energy of the
