Quantum State Geometry (QSG) - A Disformal Effective Action Framework for Cosmological Dynamics

Abstract

We introduce Quantum State Geometry (QSG) as an effective field theory linking projective Hilbert-space state evolution to spacetime metric dynamics. By coupling matter fields to a disformal effective metric governed by a scalar quantum-variancefield ϕ ≡ ∆E/MP , QSG modifies the Einstein-Hilbert action without conflating state space with spacetime topology.
