Quantum behavior of the "Little Sibling" of the Big Rip induced by a three-form field

Understand

A canonical quantization \`a la Wheeler-DeWitt is performed for a model of three-form fields in a homogeneous and isotropic universe.

• We start by carrying out the Hamiltonian formalism of this cosmological model.
• We then apply this formalism to a Little Sibling of the Big Rip (LSBR), an abrupt event milder than a Big Rip and that is known to be generic to several minimally coupled three-form fields for a variety of potentials.
• We obtain a set of analytical solutions of the Wheeler-DeWitt equation using different analytical approximations and explore the physical consequences of them.
