Effects of Strong Magnetic Fields on the Equation of State and Mass-Radius Structure of Hyperonic Neutron-Star Matter with Anomalous Magnetic Moments
W. German, T. Mello, J. P. W. Diener +1
We investigate the effects of strong magnetic fields on the equation of state (EoS) and stellar structure of cold, charge-neutral, -equilibrated hyperonic neutron-star matter wi…
The lambda hyperon and the hyperon puzzle
Wazha German, Dr Jacobus Diener
Neutron stars provide unique conditions to study cold dense nuclear matter at extreme densities. Due to these extreme conditions additional hadronic degrees of freedom are expected…
Thermodynamics of magnetized dense neutron-rich matter
J. P. W. Diener
A neutron star is one of the possible end states of a massive star. It is compressed by gravity and stabilized by the nuclear degeneracy pressure. Despite its name, the composition…
The spin-polarized ferromagnetic state of a cold Fermi gas
J. P. W. Diener, F. G. Scholtz
The spin-polarized ferromagnetic state of a cold Fermi gas is investigated for interacting and non-interacting charge-neutral and -equilibrated gases. The standard minimal coupl…
On the role of the Vacuum Energy in the Thermodynamics of Neutron Matter
J. P. W. Diener, F. G. Scholtz
The only way neutron matter can couple to the electromagnetic field is through an anomalous coupling, which plays an important role in the thermodynamics of pure neutron matter. Su…
Grand canonical potential of a magnetized neutron gas
Jacobus P. W. Diener, Frederik G. Scholtz
We compute the effective action for stationary and spatially constant magnetic fields, when coupled anomalously to charge neutral fermions, by integrating out the fermions. From th…
Ferromagnetism in neutron and charge neutral beta-equilibrated nuclear matter
J. P. W. Diener, F. G. Scholtz
Ferromagnetism in infinite neutron matter as well as beta equilibrated, charge neutral, dense, and infinite nuclear matter is investigated using a model of interacting baryons and…
Ferromagnetic Phase Transitions in Neutron Stars
J. P. W. Diener
The ferromagnetic phase in pure neutron matter as well as charge neutral, beta-equilibrated nuclear matter is considered. We employ Quantum Hadrodynamics, a relativistic field theo…
Saturated symmetric nuclear matter in strong magnetic fields
J. P. W. Diener, F. G. Scholtz
Strongly magnetized symmetric nuclear matter is investigated within the context of effective baryon-meson exchange models. The magnetic field is coupled to the charge as well as th…
Ferromagnetic phase diagram of neutron matter
J. P. W. Diener, F. G. Scholtz
The magnetic properties of matter under extreme conditions are of particular importance to understanding the neutron star interior. One contributing factor to the magnetic field of…
Relativistic mean-field theory applied to the study of neutron star properties
J. P. W. Diener
Nuclear physics can be applied in various ways to the study of neutron stars. This thesis reports on one such application, where the relativistic mean-field approximation has been…
