I'm looking for a recommendation for an up to date, introductory String Theory text and an overview of the prerequisites.
Thanks in advance.
Thanks in advance.
Demystifier said:The standard introduction is Zwiebach, A First Course in String Theory.
I also like Szabo, An Introduction to String Theory and D-brane Dynamics. (A slightly shorter version is available at arXiv.)
If you also want an introduction to AdS/CFT, the best start is Natsuume, AdS/CFT Duality User Guide. (A full version can be found at arXiv.)
Concerning prerequisites, a good knowledge of classical electrodynamics and quantum mechanics is necessary, while a basic knowledge of quantum field theory and general relativity is useful but not necessary.
String theory is a theoretical framework that attempts to reconcile the principles of quantum mechanics and general relativity by describing particles as tiny, vibrating strings rather than point-like objects. It is a candidate for a theory of everything, which would unite all known forces and explain the fundamental workings of the universe.
Unlike traditional theories, which describe particles as point-like objects, string theory proposes that particles are actually tiny, one-dimensional strings that vibrate at different frequencies. This allows for the incorporation of gravity into the framework of quantum mechanics.
One of the main challenges of string theory is that it has not yet been experimentally proven, and many physicists argue that it is currently untestable. Additionally, there are multiple versions of string theory and no consensus on which version is the correct one. Some also criticize the theory for being overly complex and lacking mathematical rigor.
While a basic understanding of physics and mathematics is helpful, many introductory string theory texts are written in a way that is accessible to those without an advanced background. However, a strong foundation in these subjects will make it easier to grasp the concepts and mathematical equations presented in the texts.
Currently, there are no practical applications of string theory. However, some scientists believe that it may lead to a deeper understanding of the universe and potentially help us develop new technologies in the future. Additionally, some concepts from string theory, such as extra dimensions, have been applied in the development of theories in cosmology and condensed matter physics.
