Download or read book Field Theory written by Ashok Das and published by World Scientific. This book was released on 1993 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, field theory is taught through canonical quantization with a heavy emphasis on high energy physics. However, the techniques of field theory are applicable as well and are extensively used in various other areas of physics such as consdensed matter, nuclear physics and statistical mechanics. The path integral approach brings out this feature most clearly. In this book, the path integral approach is developed in detail completely within the context of quantum mechanics. Subsequently, it is applied to various areas of physics.
