摘要

A matrix eigenvalue method is applied to analyse the thermodynamic stability of two-component interacting fermions. The non-relativistic and ultra-relativistic d = 1,2,3 dimensions have been discussed in detail, respectively.The corresponding stability region has been given according to the two-body interaction strength and the particle number density ratio.
