| contents | This work applies the principles of quantum cosmology to examine models incorporating a quintom field. Specifically, three distinct models are analyzed: a simplified toy model, a model featuring an exponential quintom potential, and one where the quintom field is coupled with a negative cosmological constant. For each case, we study the classical trajectories within the configuration space, present solutions to the Wheeler-DeWitt equation in quantum cosmology, and discuss physical interpretations and consequences. A key focus is the behavior of wave packets in the minisuperspace framework. Notably, the correspondence principle (connection between classical and quantum solutions) is also demonstrated. Furthermore, the appropriate quintom duality is introduced, and we discuss its consequences. A section including interesting and challenging discussions is also presented. |
