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…
