Beautifully, diverse grand theories, from the Standard Model of particle physics to cosmology, are connected to each other by a `dark' sector. Today, we understand that a mysterious non-luminous substance, called dark matter, predominates in the Milky Way's halo, our cosmic neighborhood. Our evidence of it, such as the unexpected rotational velocity of spiral galaxies, is strong yet indirect. Luckily, we infer other links of this jigsaw. Axions are long-postulated bosons that can brighten why the electric dipole moment of the neutron is observed to be minuscule, implying a tight symmetry in the strong nuclear force while, intriguingly, there is no inherent reason for it. It is exciting that the axion, an invisible pseudo-scalar particle, could stand as a key piece in the dark matter puzzle, accumulating in the Halo and also favoring the formation of dark matter substructures. The 2012 discovery of the Higgs boson, our first scalar particle as axion is, is a promising sign that we should turn our efforts towards uncovering these, elusive, axions. To continue exploring under-examined, cosmologically tantalizing sectors, we need fresh experimental approaches. The DALI Experiment brings promising prospects for probing dark matter axions passing through a lab on Earth, as its concept is technologically affordable and yet highly sensitive over a vast mass range which remains underexplored owing to the challenge associated with the development of the hardware needed to probe it. 

This project also aims to pave the way for DALI; and put at the reach of the research community a powerful means of accessing axions arising in a postinflationary Universe.
