Despite the recent successes of ab initio calculations, nuclear structure is still far from being understood from the point of view of a fundamental theory, namely Quantum Chromodinamics. One of the main features of this theory, chiral symmetry, is being exploited to thoroughly study the hadron spectrum. The Nambu-Goldstone mesons of the broken symmetry are the pions, that dominate the long range part of the nucleon-nucleon interaction. We introduce in this seminar the Tensor Optimized Shell Model, that exploits the tensor features of the pion interaction to study the structure of light closed shell nuclei in a shell model space. We show results for the ground state of 4He and halo nuclei.
