Title: Boltzmann or Bogoliubov? A Case of Gravitational Particle Production
Abstract: Despite being the weakest force in nature, gravity is a fundamental source of particle production in the early universe. All particles, including dark matter, are necessarily produced after the end of inflation. Two approaches have been commonly considered to study this production process: one based on the Boltzmann equation and the other based on the Bogoliubov transformation. The former is widely used in phenomenological studies of dark matter, while the latter was developed to describe particle production in curved spacetime. By considering the pure gravitational production of a scalar particle, we would like to discuss when these two approaches are equivalent and when they are not.
