In this work we calculate some exotic nuclear phase properties of the neutron-proton-electron matter known as “nuclear pasta” in the context of the Walecka model at zero temperature. We extend the usual spherical Thomas-Fermi Approximation by including non-spherical terms in the density and energy expansions in order to properly describe geometry deviations in the complex structures commonly found in the nuclear pasta, for instance, droplet, rod and slab. Numerical solutions to this problem are not a simple task due to the loss of spherical symmetry in the fields description. However, our preliminary results suggest the possibility for new low-energy structures comprising prolate-oblate deviations of spherical symmetry.
