A bstractWe show that the recently proposed multi-natural inflation can be realized within the framework of 4D $ \mathcal{N} $ = 1 supergravity. The inflaton potential mainly consists of two sinusoidal potentials that are comparable in size, but have different periodicity with a possible non-zero relative phase. For a sub-Planckian decay constant, the multi-natural inflation model is reduced to axion hilltop inflation. We show that, taking into account the effect of the relative phase, the…
