1Unified properties of a weakly interacting Fermi gas in a weak magnetic field显示文摘When the orbital motion and the spin motion of particles were considered simultaneously,the thermodynamic potential function of a weakly interacting Fermi gas in a weak magnetic field was derived using the thermodynamics method. Based on the derived expression,the analytical expressions of energy,heat capacity,chemical potential,susceptibility and stability conditions of the system were given,and the effects of the interparticle interactions as well as the magnetic field on the properties of the system were analyzed. It was shown that the magnetic field always causes energy and stability to decrease,while the chemical potential of the system to increase. The repulsive(attractive) interactions always increase(decrease) energy and stability,but decrease(increase) the chemical potential and paramagnetism. The repulsive(attractive) interactions decrease(increase) heat capacity of the system at high temperatures but increase(decrease) it at low temperatures.MEN FuDian LIU Hui ZHU HouYu 2008Science China(Physics,Mechanics & Astronomy)2008,51,8:4
2Thermal stability conditions of a weakly interacting Fermi gas in a weak magnetic field显示文摘On the basis of the results derived from pseudopotential method and ensemble theory,thermal stability of a weakly interacting Fermi gas in a weak magnetic field is studied by using analytical method of thermodynamics.The exact analytical expressions of stability conditions at different temperatures are given,and the effects of interactions as well as magnetic field on the stability of the system are discussed.It is shown that there is an upperlimit magnetic field for the stability of the system at low temperatures,and there is an attractive dividing value at high temperatures.If attractive interaction is lower than the critical value,the stability of the system has no request for magnetic field,but if attractive interaction is higher than the dividing value,a lower-limit magnetic field exists for the stability of the system.Fudian Men Hui Liu Houyu Zhu 2009Progress in Natural Science:Materials International2009,19,1:1
3Thermostatistic Properties of the Relativistic q-Deformed Ideal Fermi Gas at High Temperature显示文摘The q-deformed Fermi-Dirac distribution is used to study the high-temperature(T TF) ∨behavior of a relativistic q-deformed ideal Fermi gas. The effects of the q-deformation and relativity on the properties of the system are discussed,and then,the example of the neutrinos near the surface of the earth is used to calculate approximately. It shows that the q-deformation increases the total energy but decreases the chemical potential and heat capacity,whereas mc 2 ε F0increases the chemical potential and total energy but decreases the heat capacity( ε F0is the Fermi energy of ultrarelativistic undeformed Fermi gas) . The larger the deformation parameter q and the value of mc 2 ε F0are,the more remarkable the effects of them on the thermostatistic properties will be. However,the effects of both q-deformation and relativity become weak with increasing temperature. When the temperature T →∞,the thermostatistic properties of the system are reduced to those of ordinary Boltzmann gases and independent of q and relativity effect completely,which implies that the q-deformation is a pure quantum effect.LIU Hui MEN Fudian LI Yong GUAN Banggui ZHANG Maolian 2010Wuhan University Journal of Natural Sciences2010,15,1:0
