The neutron-rich nucleus \(^{54}{\rm{Ca}}\) which far-stable-line isotope are recently considered since experimental evidence of this isotope related to the new nuclear ‘magic number’. Especially, with \(N = 34\), the orbital \(3{{\rm{s}}_{{\rm{1/2}}}}\) in the neutron shell of \(^{54}{\rm{Ca}}\) is not occupied and can cause the bubble structure in the neutron density. Therefore, we calculate microscopically the nucleon (proton/neutron) density to examine the existence of the “bubble” structure at the zero and finite temperature. Particularly, establishing Skyrme-Hartree-Fock mean field plus thermal exact pairing solution (FTEP) described mainly nucleon density of \(^{54}{\rm{Ca}}\). The obtained results show the existence of the neutron bubble in \(^{54}{\rm{Ca}}\) and the disappearance of this structure with increasing temperature.
