Abstract
We investigate the implications of the interactions between ultralight dark matter (ULDM) and the Standard model particles for the effective self-interaction coupling constants of ULDM. Our analysis shows that one-loop quantum corrections can result in a substantial increase in the effective coupling constant, which is tightly constrained by cosmological observations. Our findings highlight the importance of considering quantum corrections in the detection of ULDM.
