Equivalent Hamiltonian approach to quantum cosmology of integrable models
Nahomi Kan, Masashi Kuniyasu, Kiyoshi Shiraishi +1
We propose an approach to quantum cosmology of integrable models. To analyze the models with two dynamical variables, we introduce equivalent Hamiltonians in reduced phase spaces,…

Accelerating cosmologies in an integrable model with noncommutative minisuperspace variables
Nahomi Kan, Masashi Kuniyasu, Kiyoshi Shiraishi +1
We study classical and quantum noncommutative cosmology with a Liouville-type scalar degree of freedom. The noncommutativity is imposed on the minisuperspace variables through a de…
