What should i study for Quantum Mechanics

AI Thread Summary
To begin learning quantum mechanics, foundational knowledge in mathematics and physics is essential. Key mathematical topics include calculus, differential equations, linear algebra, and operator theory. In physics, a solid understanding of classical mechanics, electromagnetism, and special relativity is crucial, typically covered in the first two years of an undergraduate program. Recommended resources include introductory texts like Zetilli's Quantum Mechanics, which should be worked through thoroughly, including examples and problems.For those aiming to delve deeper into quantum mechanics, familiarity with Hamiltonian and Lagrangian mechanics, advanced differential equations, complex analysis, and abstract algebra is necessary. This advanced material can often be studied alongside introductory quantum mechanics. Overall, a structured approach through undergraduate-level courses in both math and physics is the best pathway to mastering quantum mechanics.

I want to start learning quantum mechanics but i have no idea where to start . I want to know which other fileds and physics branches i have to study before quantum mechanics and if i want to go more deeply for this (like taking a graduate course ) what should i study before this in physics math and chemestery

Maths, calculus, differential equations, linear algebra and eventually operator theory. Physics, study all the basic physics first like Newtonian mechanics, Electromagnetism, special relativity and basic modern physics. Basically what you learn in a physics course at uni, until you get to quantum in 3rd year usually.

Then pick up a friendly book like Zetilli's Quantum mechanics and work through it thoroughly, do the worked examples and some problems.

Quantum mechanics is nowhere near a graduate-level course - you'll meet it no later than the second year of an undergraduate physics program and will still be many years of study away from the stuff that gets covered in A-level threads here.

To get through the first course in quantum mechanics, you will need
- Math: Multi-variable and vector calculus, elementary complex analysis, elementary and multi-variable differential equations, elementary linear algebra. This material is covered in more or less the second year of a college-level math program (a serious treatment of elementary differential and integral calculus is the first year).
- Physics: Classical mechanics at the level of Kleppner and Kolenkow or equivalent, E&M at the level of Purcell or equivalent, and then a semester on wave phenomena.

If you're going to go beyond introductory QM you will need the Hamilton/Lagrange formulation of classical mechanics, much more differential equations and complex analysis, and a serious course on abstract algebra. This can be studied in parallel with your intro QM class.

The answer hasn't really changed since Thursday, the last time you asked it.
If you can see well the last time i asked about cosmology and gravity , and i asked in which branch we can put them not what to study for them
 
People can still read what you read in that thread - even the part where you think you don't need E&M to study QM. The advice there was spot on.
 

Thread 'Hepth programs in Europe'

After a year of thought, I decided to adjust my ratio for applying the US/EU(+UK) schools. I mostly focused on the US schools before, but things are getting complex and I found out that Europe is also a good place to study. I found some institutes that have professors with similar interests. But gaining the information is much harder than US schools (like you have to contact professors in advance etc). For your information, I have B.S. in engineering (low GPA: 3.2/4.0) in Asia - one SCI...

Thread 'Should I pursue a masters degree after 4.5 years working in IT?'

I graduated with a BSc in Physics in 2020. Since there were limited opportunities in my country (mostly teaching), I decided to improve my programming skills and began working in IT, first as a software engineer and later as a quality assurance engineer, where I’ve now spent about 3 years. While this career path has provided financial stability, I’ve realized that my excitement and passion aren’t really there, unlike what I felt when studying or doing research in physics. Working in IT...

Thread 'Tips for a CS and physics major'

Hello, I’m an undergraduate student pursuing degrees in both computer science and physics. I was wondering if anyone here has graduated with these degrees and applied to a physics graduate program. I’m curious about how graduate programs evaluated your applications. In addition, if I’m interested in doing research in quantum fields related to materials or computational physics, what kinds of undergraduate research experiences would be most valuable?
