Path Integrals in Quantum Theories: A Pedagogic First Step
by Robert D. Klauber
Publisher: QuantumFieldTheory.info 2011
I strongly believe it far easier, and more meaningful, for students to learn QFT first by the canonical quantization method, and once that has been digested, move on to the path integral (many paths) approach. Hopefully, this material will help such students, as well as those who are forced to begin their study of QFT via path integrals.

These lectures are intended as an introduction to the technique of path integrals and their applications in physics. The audience is mainly first-year graduate students, and it is assumed that the reader has a good foundation in quantum mechanics.

These lectures aim at giving graduate students an introduction to and a working knowledge of path integral methods in a wide variety of fields in physics. The text deals with non-relativistic quantum mechanics, many-body physics and field theory.

We describe Feynman's path integral approach to quantum mechanics and quantum field theory from a functional integral point of view, where focus lies in Euclidean field theory. Gaussian measure and the construction of the Wiener measure are covered.
