Aligned natural inflation with modulations
Kiwoon Choi, Hyungjin Kim
The weak gravity conjecture applied for the aligned natural inflation indicates that generically there can be a modulation of the inflaton potential, with a period determined by su…

Primordial perturbations from dilaton-induced gauge fields
Kiwoon Choi, Ki-Young Choi, Hyungjin Kim +1
We study the primordial scalar and tensor perturbations in inflation scenario involving a spectator dilaton field. In our setup, the rolling spectator dilaton causes a tachyonic in…
