I am looking for a textbook that introduces and discusses the path integral formulation of non-relativistic quantum mechanics? Would you have some suggestions for me? Thanks.
The path integral formulation is a mathematical framework for describing the behavior of quantum systems. It involves summing over all possible paths that a particle can take in order to calculate the probability of different outcomes.
The path integral formulation is based on a probabilistic approach, rather than the wave function approach used in the Schrödinger equation. It also allows for the incorporation of time-dependent potentials and can be extended to include relativistic effects.
The path integral formulation provides a powerful tool for calculating the behavior of quantum systems, especially in complex situations where other methods may be difficult to apply. It also helps to bridge the gap between classical and quantum mechanics.
One of the main challenges is the requirement to sum over an infinite number of possible paths, which can be computationally intensive. Additionally, the interpretation of the path integral can be difficult, as it involves considering all possible paths, including those that may seem physically impossible.
The path integral formulation has been used in a wide range of applications, including quantum field theory, condensed matter physics, and quantum information theory. It has also been applied to problems in finance, biology, and other fields where probabilistic calculations are needed to describe complex systems.
