Our understanding of the state of the universe between the end of inflation and big bang nucleosynthesis (BBN) is incomplete. The dynamics at the end of inflation are rich and a potential source of observational signatures. Reheating, the energy transfer between the inflaton and Standard Model fields (possibly through intermediaries) and their subsequent thermalization, can provide clues to how inflation fits in with known high-energy physics. We provide an overview of our current understanding of the nonperturbative, nonlinear dynamics at the end of inflation, some salient features of realistic particle physics models of reheating, and how the universe reaches a thermal state before BBN. In addition, we review the analytical and numerical tools available in the literature to study preheating and reheating and discuss potential observational signatures from this fascinating era.

• Challenges and opportunities of gravitational-wave searches at MHz to GHz frequencies (2020, background): “Preheating is an out-of-equilibrium production of particles due to non-perturbative effects [105– 114], which takes place after inflation in many models of particle physics (see [115–117] for reviews).”
• Dark photon dark matter produced by axion oscillations (2018, unknown): “[31, 32]) and has been discussed as a mechanism to produce vector fields in the context of generating primordial magnetic fields [33–35].”
• CMB-S4 Science Case, Reference Design, and Project Plan (2019, unknown): “Violent phase transitions and other nonlinear dynamics in the primordial Universe could produce such a background, peaked at frequencies much larger than those accessible to B-mode polarization measurements of the CMB or, in many cases, direct detection experiments such as LIGO and LISA [206, 207, 2”
