Spinorial Wheeler-DeWitt wave functions inside black hole horizons
Nahomi Kan, Takuma Aoyama, Kiyoshi Shiraishi
We revisit the solutions of the Wheeler-DeWitt (WDW) equation inside the horizons of spherical black holes and planar topological black holes in arbitrary dimensions. For these sys…
Classical and quantum bicosmology with noncommutativity
Nahomi Kan, Takuma Aoyama, Kiyoshi Shiraishi
Recently, Falomir, Gamboa, Mendez, Gondolo and Maldonado proposed a bicosmology scenario [1-4] for solving some cosmological problems related to inflation, dark matter, and thermal…
Third quantization for scalar and spinor wave functions of the Universe in an extended minisuperspace
Nahomi Kan, Takuma Aoyama, Taiga Hasegawa +1
We consider the third quantization in quantum cosmology of a minisuperspace extended by the Eisenhart-Duval lift. We study the third quantization based on both Klein-Gordon type an…
Eisenhart--Duval lift for minisuperspace quantum cosmology
Nahomi Kan, Takuma Aoyama, Taiga Hasegawa +1
We study covariant equations in quantum cosmology of an extended minisuperspace obtained by the Eisenhart--Duval lift. We find that a Dirac-type equation is naturally introduced in…
