Abstract: | Based on the thermodynamic potential function of Fermi gas
in a strong magnetic field, using the thermodynamics method, the
integrated analytical expressions of thermodynamic quantities of the
system at low temperatures are derived, and the effects of the
magnetic field on the statistic properties of the system are
analysed. It is shown that, as long as the temperature is not zero, the
effects of the magnetic field on the thermodynamic quantities of the
system contain both oscillatory and non-oscillatory parts. For the
non-oscillatory part, compared with the situation of Fermi gas in a
weak magnetic field, the influence of the magnetic field on the
thermodynamic quantities is not exactly the same. For the
oscillatory part, the period and amplitude of the oscillation are
all related to the magnetic field. Due to the oscillation, the chemical
potential may be greater than Ferim energy of the system, but the
oscillation does not affect the thermodynamic stability of the
system. |
