Wheeler-DeWitt equation for holographic vacuum dynamics: Minisuperspace reduction and structural results
Year: 2026
Type: preprint
Abstract: The minisuperspace Wheeler–DeWitt equation for a two-field vacuum system — a radial Kähler modulus and an angular axion in a landscape potential — reduces from a three-variable PDE to a one-variable ODE plus an integer quantum number, through exact U(1) factorisation (valid to 10⁻¹²²) and Friedmann-constraint elimination. Nine structural results follow, including a selection rule under which transient expansion features exist only for nonzero quantum number, and identification of the axion with a conifold complex-structure mode of mass ≈ 2.3 H₀, implying a single DESI peak. Keywords: quantum cosmology, Wheeler–DeWitt equation, minisuperspace, dark energy, axion, moduli, string landscape, DESI, gr-qc, hep-th
