The lack of direct detections for weakly interacting massive particles has led theorists to think about more exotic scenarios for producing DM in the early Universe. One viable alternative is gravitational particle production i.e. the creation of particles through due to the presence of a sufficiently strong gravitational field. In this talk, I will go over how this mechanism can be used to produce a viable free scalar field dark matter candidate and how these results can be extended to a self-interacting scalar field.
