摘要：

Correlations in quantum fluids such as liquid He-3 continue to be of high interest to scientists. Based on this prospect, the present work is devoted to study the effects of spin spin correlation function on the thermodynamic properties of polarized liquid He-3 such as pressure, velocity of sound, adiabatic index and adiabatic compressibility along different isentropic paths, using the Lennard Jones potential and employing the variational approach based on cluster expansion of the energy functional. The inclusion of this correlation improves our previous calculations and leads to good agreements with experimental results.
