Should i take intro solid state phy without background of quantum phy?

Click For Summary

Discussion Overview

The discussion revolves around whether a student should take an introductory solid state physics course without prior knowledge of quantum physics. The conversation includes considerations of course content, prerequisites, and personal experiences related to the challenges of the subject matter.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant expresses uncertainty about taking the course without a quantum physics background, citing conflicting advice from advisors regarding the difficulty level.
  • Another participant suggests consulting the professor for guidance on the course's requirements.
  • Some participants recommend reviewing previous years' homework and tests to gauge the course's demands.
  • A participant shares their experience of successfully taking a solid state course without prior quantum knowledge, emphasizing the interdisciplinary nature of solid state physics and the potential value of backgrounds in thermodynamics and statistical mechanics.
  • It is noted that the course syllabus includes topics that may or may not require quantum mechanics, with specific mention that crystal structures and symmetry do not heavily rely on quantum concepts, while lattice vibrations and energy bands may present challenges without quantum understanding.
  • One participant warns against generalizing advice based on different curricula, emphasizing the need for specific knowledge about the courses being taken.
  • Another participant shares their positive experience in a similar course, indicating that they expect to perform well despite lacking a quantum background, and suggests that the textbooks used are manageable.
  • Some participants suggest that while taking quantum first could be beneficial, it may not be necessary, and dropping the course is an option if it becomes too challenging.

Areas of Agreement / Disagreement

Participants express differing opinions on the necessity of a quantum physics background for success in the solid state course. While some believe it is manageable without prior knowledge, others caution that it may depend on the specific curriculum and course structure.

Contextual Notes

There are limitations in the discussion regarding the specific curricula of the courses mentioned, as well as the varying experiences of participants which may not be applicable to all students.

I do not know anything about quantum physics, but due to some timetable clashes i hv to take intro solid state and intro quantum phy in the same semester.

One advisor said its ok and he said intro solid state phy is only abt memorizing crystal, but another advisor said it would be tough without knowledge of quantum?i am confused.

The syllabus is:
Crystal structures and symmetry. The reciprocal lattice and X-ray diffraction in crystals. Lattice vibrations. Free-electron theory of metals. Energy bands; metals, semiconductors, and insulators. Dielectric and magnetic properties.

So should i take it?( i have taken statistical mechanics before)

You should ask the professor who is teaching the course.
 
Also if you can't get in touch with the professor, take a look at previous years homework and tests.
 
I'm currently taking an undergraduate solid state course without having taken the Quantum that precedes it in the series. You may have to work a little harder than those that have some quantum background but you should be fine. Solid State is very interdisciplinary, having a background in thermodynamics, statiscial mechanics and classical mechanics will probably be more valuble than Quantum.
 
QM is the prerequisite for the Intro. to Solid State course at my university. I wanted to take it this semester but couldn't. A couple of buddies of mine are, though. I think the course takes the ODE QM approach.

You might be able to get by, if this is the order in which things are covered. Crystal structures you don't rely on quantum mechanics, nor does reciprocal lattice and x-ray scattering. Lattice vibrations is where things will get tricky, to understand phonons, you'll need to understand the energy levels of a harmonic oscillator. The free-electron theory of metals requires some quantum mechanics, but if you are willing to take the Pauli-Exclusion principle on faith, you'll be fine. Energy bands, though, requires some understanding of the Schroedinger equation.

If you end up trying, pick up an introductory book on quantum mechanics to use as a reference.

This is terrible, terrible advice. Unless you are taking the same courses at the same university from the same professors, you don't know this. I've seen curricula where the OP would be in great shape, and I've seen curricula where the OP would get squashed like a bug. To decide which is which, we would need to know what exactly is covered in the two classes, and we don't.

But the professor does.

These are nearly exactly the topics I've covered this quarter, I've never taken quantum, I'm expecting an A. The other students who've taken quantum spend the same amount of time on homework I do. Undergraduate Intro to Solid should be a pretty standard curriculum. The book for your class is probably Omar or Kittel both of which are very do-able for me especially
within the topics you've listed.

Having said that, If it won't delay your graduation taking quantum first I'm sure would help. But if you want to and they'll let you I'd take it, if you're in over your head you can always drop.
