SUMMARY

The discussion centers on the relationship between string theory and the nonlocality of particles and waves. Participants clarify that while string theory is relativistically covariant, it does not inherently support nonlocality as a fundamental property of strings. The conversation highlights the distinction between the wave-particle duality of quantum mechanics and the behavior of strings, emphasizing that the quantization of strings leads to wavelike states without implying nonlocality. Ultimately, string theory does not provide a satisfactory explanation for nonlocality, which remains a complex issue in quantum mechanics.

PREREQUISITES
  • Understanding of string theory fundamentals
  • Familiarity with quantum mechanics concepts, particularly wave-particle duality
  • Knowledge of relativistic covariance and its implications
  • Basic grasp of quantum entanglement and its effects
NEXT STEPS
  • Research the implications of relativistic covariance in quantum field theories
  • Explore the mathematical framework of string theory, including its quantization methods
  • Study the concept of nonlocality in quantum mechanics and its experimental validations
  • Investigate alternative theories that address nonlocality beyond string theory
USEFUL FOR

Physicists, theoretical researchers, and students interested in the intersections of string theory, quantum mechanics, and the nature of nonlocality in fundamental physics.

Two strings can be nonlocally entangled in the same way as two particles can be nonlocally entangled. However, as a single string is nonlocal by itself, there is an additional form of nonlocality in string theory - an entanglement between different parts of the string.

The hidden-variable formulations of quantum mechanics make this entanglement nonlocality manifest. The most successfull hidden-variable theory is the Bohmian interpretation. For the case of strings see

But can string theory bring a new explanation of this nonlocality? In
http://arxiv.org/abs/hep-th/0512186
it is suggested that the Bohmian interpretation can be DERIVED from string theory, so in this sense the answer could be - yes!
