Axion monodromy inflation, trapping mechanisms and the swampland [PDF]
European Physical Journal C: Particles and Fields, 2021 We study the effects of particle production on the evolution of the inflaton field in an axion monodromy model with the goal of discovering in which situations the resulting dynamics will be consistent with the swampland constraints. In the presence of a

Implications of time-dependent inflaton decay on reheating and dark matter production
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2022 We discuss the production of radiation and dark matter assuming a time-dependent inflaton decay rate during the reheating period. It is shown that the time dependence of the inflaton decay rate can substantially modify the reheating dynamics.

Universe, 2023 Toward the systematic search for axion-like particles in the eV mass range, we proposed the concept of a stimulated resonant photon collider by focusing three short pulse lasers into a vacuum.

Universe, 2021 We explore a possibility to detect dark components in the Universe via stimulated photon–photon collisions by focusing two-frequency coherent electromagnetic fields in a vacuum.

Universe, 2022 We propose a three-beam stimulated resonant photon collider with focused laser fields in order to directly produce an axion-like particle (ALP) with the two beams and to stimulate its decay by the remaining one.

Inflaton as a pseudo-Nambu-Goldstone boson
Physics Letters B, 2023 In the realistic model of cosmic inflation the inflaton potential should be flat and stable under quantum corrections. It is natural to imagine that there is some symmetry behind and an idea of the inflaton as a Nambu-Goldstone boson of spontaneous ...

Measuring inflaton couplings via primordial gravitational waves
Journal of High Energy Physics, 2023 We investigate the reach of future gravitational wave (GW) detectors in probing inflaton couplings with visible sector particles that can either be bosonic or fermionic in nature.

Pseudo-Nambu-Goldstone inflation with twin waterfalls
Physics Letters B, 2022 We propose a pseudo-Nambu-Goldstone inflation where twin waterfall fields coupled to the inflaton are responsible for the graceful exit from inflation by a waterfall transition.

Inflection-point inflation and dark matter redux
Journal of High Energy Physics, 2022 We investigate for viable models of inflation that can successfully produce dark matter (DM) from inflaton decay process, satisfying all the constraints from Cosmic Microwave Background (CMB) and from some other observations.
