| Abstract: | The low-temperature thermodynamic variables of
entropy, internal energy and specific heat capacity of a liquid 3He-4He binary system have been studied.
The system showed a remarkable discontinuity in internal energy at about 2.14 K.
In the binary mixtures, the bosonic components have been studied by means of
modified Gross-Pitaevskii (GP) approximations and the fermionic components by
Thomas-Fermi (TF) approximations. Equations for particle and energy
distributions have been developed. The effects of the nature of scattering
lengths have been studied. Implications on selected Bose-Fermi mixtures such as
7Li-6Li
and 41K-40K are
discussed. |
