Abstract：
Within the isospin dependent Extended Brueckner-Hartree-Fock framework, the Hugenholtz-Van Hove theorem in isospin asymmetric nuclear matter has been investigated and discussed for different orders of approximation made according to the truncation levels in the hole-line expansion of mass operator. The neutron and proton Fermi energies have been calculated. It is found that both the rearrangement contributions and renormalized corrections in the hole-line expansions of the neutron and proton mass operators are necessary for getting a satisfactory fulfillment of the Hugenholtz-Van Hove theorem, indicating the importance of ground state correlations to the single particle properties of asymmetric nuclear matter.
