In this paper, we define a new geometric vector field on (semi-)Riemannaian manifolds. These new vector fields on 3-dimensional Walker manifolds will be derived. Then, we study Ricci solitons admitting this new vector field (called semi-Killing vector field) as their potential. In Riemannain setting, we prove that Ricci solitons with semi-Killing potential vector field are Einstein. Also, It will be shown that such Lorentzian solitons have constant scalar curvature. Finally, application of this new structure in physics will be investigated. In fact, we propose that semi-Killing vector fields are in relation to the notion of dark energy in general relativity.
