Hello, I'm already done with undergraduate Electrical Engineering and was quite disappointed not to have studied Quantum Mechanics. I have some free time now and would like to know whether its possible to get a good grasp of the subject the same way physicists do. I'm not talking about popular science QM, I'm talking about the QM that'll broaden my knowledge in Semiconductor Physics, nanoelectronics etc. What I'm unsure of is the level of Maths needed. As I mentioned, I'm just an EE. So, the type of Maths that I'm familiar with is: Linear Algebra, Calculus up to introduction into calculus of variations, ODE, some PDE and some Complex Analysis. I would also like recommendations of self study books that are reasonable for my background. Once, I decided to learn real analysis and someone recommended the book by Rudin. I had to put down the book before going anywhere. So, I'm not asking for any advanced text to learn about the nuances of QM. Thank You.
