We study the symmetric nuclear matter using bare nucleon-nucleon ($NN$)interactions with finite particle-number approach within finite cubic boxes.Due to the $NN$ correlations originating from bare $NN$ interaction, twonucleons can be excited to the high-momentum region, leading to the increase ofthe kinetic energy in nuclear matter. We further consider the spin excitationsin the nucleon pairs, where the spin of the two nucleons are changed, and thisexcitation is important for the tensor correlation. The unitary correlationoperator method (UCOM) is used to treat the short-range correlation. The tailcorrection coming from the neighbouring boxes is also included. We demonstratethe contributions of various excitations of nucleon pairs as well as the tailcorrection to the total energy at the normal density. We also discuss theeffects of UCOM and correlated nucleon pairs on the density dependence of thetotal energy. We calculate the equations of state of symmetric nuclear matterusing two kinds of the Argonne potentials and the results agree with those fromother many-body theories. The density dependences of the Hamiltonian componentsare also shown.
