EvoEMD: cosmic evolution with an early matter-dominated era

EvoEMD provides a framework to estimate the cosmic relics in the Universe with an early matter-dominated era.

Features

  • Global parameter system
  • Global particle system
  • Global process system
  • Different methods for Hubble parameter calculation
  • Automatically build up the Boltzmann equation according to the user's definition of particle and process
  • Solving the Boltzmann equation using 4th order Runge-Kutta method with adaptive steps tailored to Cosmology application
  • Cache the collision rate calculation results for fast evaluation
