Information Spreading in Interacting String Field Theory

TL;DR

This paper investigates the behavior of the string field commutator in light cone string field theory, revealing it does not vanish outside the light cone, which could impact our understanding of information localization in quantum gravity.

Contribution

It demonstrates that the string field commutator remains non-zero outside the light cone, challenging assumptions about locality in string theory and quantum gravity.

Findings

The string field commutator is generally non-zero outside the light cone.

This non-vanishing could influence theories of information localization.

Implications for quantum gravity and string theory locality.

Abstract

The commutator of string fields is considered in the context of light cone string field theory. It is shown that the commutator is in general non--vanishing outside the string light cone. This could have profound implications for our understanding of the localization of information in quantum gravity.
