The analysis is performed within the microscopic Brueckner\u2013Hartree\u2013Fock approach using the Argonne V18 potential plus a Urbana IX three-nucleon force. Our results show that the potential part of the nuclear Hamiltonian, and in particular its tensor component, gives the largest contribution to the symmetry energy. The decomposition of the symmetry energy into a kinetic part and a potential energy part provides physical insight on the correlated nature of the system, indicating that pure neutron matter is less correlated than symmetric nuclear matter.<\/jats:p>","DOI":"10.3390\/sym7010015","type":"journal-article","created":{"date-parts":[[2014,12,29]],"date-time":"2014-12-29T10:58:34Z","timestamp":1419850714000},"page":"15-31","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Effect of Tensor Correlations on the Density Dependence of the Nuclear Symmetry Energy"],"prefix":"10.3390","volume":"7","author":[{"given":"Isaac","family":"Vida\u00f1a","sequence":"first","affiliation":[{"name":"Center of Computational Physics, Departement of Physics, University of Coimbra, Coimbra PT-3004-516, Portugal"}]},{"given":"Constan\u00e7a","family":"Provid\u00eancia","sequence":"additional","affiliation":[{"name":"Center of Computational Physics, Departement of Physics, University of Coimbra, Coimbra PT-3004-516, Portugal"}]},{"given":"Artur","family":"Polls","sequence":"additional","affiliation":[{"name":"Departament d'Estructura i Constituents de la Mat\u00e8ria and Institut de Ci\u00e8ncies del Cosmos, Universitat de Barcelona, Avda.
