Gravitational self-localization in quantum measurement
Tamas Geszti
abstract: Within Newton-Schr\"odinger quantum mechanics which allows gravitational
self-interaction, it is shown that a no-split no-collapse measurement scenario
is possible. A macroscopic pointer moves at low acceleration, controlled by the
Ehrenfest-averaged force acting on it. That makes classicality self-sustaining,
resolves Everett's paradox, and outlines a way to spontaneous emergence of
quantum randomness. Numerical estimates indicate that enhanced short-range
gravitational forces are needed for the scenario to work. The scheme fails to
explain quantum nonlocality, including two-detector anticorrelations, which
points towards the need of a nonlocal modification of the Newton-Schr\"odinger
coupling scheme.
