Wavefunction Collapse in String Theory

TL;DR

This paper explores a novel connection between wavefunction collapse models and string theory, proposing that cosmic acceleration driven by instant folded strings can produce a naturally colored noise, reducing experimental constraints compared to traditional models.

Contribution

It introduces a string theory-based mechanism for wavefunction collapse with colored noise, linking cosmic acceleration to quantum measurement processes.

Findings

String theory can produce a wavefunction collapse mechanism with colored noise.

The scenario is less constrained by experiments than the Diosi Penrose model.

Cosmic acceleration may be related to quantum measurement phenomena.

Abstract

One of the most intriguing proposals for wavefunction collapse is the Diosi Penrose model, in which collapse is driven by stochastic fluctuations of the Newtonian potential. We argue that a closely related effective structure can emerge in string theory if, as recently suggested, the present cosmic acceleration is sourced by instant folded strings and their decay products. A key difference, however, is that in this stringy setting the noise is naturally colored in time rather than white. As a result, the scenario is significantly less constrained by existing experiments than the standard Diosi Penrose model.
