Quantum Mechanics-I
A course given at University of Hyderabad
Summer Semester May14 - July10 (2018)

 

This course aims to introduce wave mechanics with minimal mathematics preparation. No vector spaces are required as prerequisite.

The postulates are adopted  for a wave mechanical treatment ofa single particle moving in a potential. Formal vector spaces and abstract approach can be taken up at a later stage of learning.

This course is suitable for those who want to come to Schrodinger equation and applications as quickly as possible.

This course will consist of following parts.

  Part-A Rise of Quantum Theory  

  Inadequacy of classical theories. Landmarks in rise of quantum theory.
  Review of classical and quantum particle and wave concepts. Uncertainty
  principle. The changes and new concepts brought in by quantum theory.
  Wave mechanics of a single point particle.
