Quantum theory is increasingly a part of many practical developments, from materials science and nanotechnology to quantum computation. Deeper insights and exposure to novel computational approaches in it will be of use to a wide audience. Specifically within theories of elementary particles, a grasp of this method is a stepping stone to more advanced topics such as String Theory.
INTENDED AUDIENCE: Students of final year of B.Sc.(Physics/Mathematics), final year of B.Tech, M.Sc and PhD students.PREREQUISITES: Relativistic Quantum Mechanics and free scalar field quantisation
