How does string theory fit with QFT?

Click For Summary
SUMMARY

String theory conceptualizes particles as vibrating strings, while Quantum Field Theory (QFT) describes them as excitations within a quantum field. Perturbative string theory positions QFT as an approximation of string theory, suggesting compatibility between the two frameworks. Non-perturbative string theory introduces conjectures that propose equivalence between string theory and QFT. This discussion highlights the potential for integrating the frequency of vibrations in string theory with the behavior of quantum particles in QFT.

PREREQUISITES

In string theory, particles is vibrating strings. However, QFT treats particles as excitations in a quantum field. Can both of these theories be correct? If so, how does them fit together?

In perturbative string theory, QFT can be viewed as an approximation of string theory. In non-perturbative string theory, there are conjectures claiming that string theory and QFT can be equivalent.

Well if QFT explains quantum particles as vibrations in a field then using string theory, you can apply each vibration's frequency according to the molecules being strings?
