We scrutinize various scenarios where such dark matter of spin 0 and 1/2 interacts with electrons via an exchange of vector, scalar, axial-vector or pseudo-scalar mediators. In particular, we examine a novel thermal dark matter scenario where present-day annihilation of dark matter in the galactic center or in the Sun may produce subdominant but detectable boosted stable particles via neutral-current-like interactions. Surprisingly, their phenomenology is very different from that of single-candidate, providing a new avenue for dark matter experiments. In this talk, we go beyond single-candidate dark matter by focusing on two-component dark matter candidates. Though they provide testable hypotheses at various experiments, little attempt has been made beyond single-candidate dark matter. A myriad of models have been proposed, the majority of which introduce a single dark matter candidate for simplicity. While we have accumulated sufficient cosmological evidence supporting its existence, the character of the dark matter particle is still unknown. Dark matter is one of the most interesting fundamental puzzles of our universe.
