Quantum Quantum Textbook For Density Matrix, Pure & Mixed States, +more

AI Thread Summary
The discussion centers on the challenges faced in a Quantum Mechanics course that is delivering a substantial amount of material quickly, with unclear PowerPoint notes and limited access to the professor. The main focus is on finding a suitable textbook to self-study key concepts introduced in class, including angular momentum algebra, ladder operators, number states, coherent states, squeezed states, pure and mixed states, entanglement, and quantum teleportation. The participant has a foundational understanding from Griffiths' textbook and is seeking recommendations for books that cover quantum optics and quantum information, with a specific mention of Ballentine's "Quantum Mechanics: A Modern Development" as a potential resource.

A Quantum Mechanics course I am taking is dumping a lot of material on us in a very short time. It's difficult to talk to the professor, and the only assigned class notes are PowerPoint slides which are not clear. So I am looking for a textbook that I can use to teach myself the material.

In our last lecture we were introduced to the following concepts, I would like a text that covers these as well:
  • Relation between angular momentum algebra and the algebra of independent oscillators
  • Something about how the ladder operators for the harmonic oscillator relates to creation and annihilation operators for bosons (not sure what the latter means)
  • Number states
  • Coherent states
  • Squeeze states
  • Squeezed coherent states
  • Pure and mixed states
  • Entanglement
  • Reduced density operator + density operator
  • Quantum teleportation

For the quantum mechanics work we had previously done, we were mostly working from Griffiths, so that is the level of understanding I am coming from.

Thread 'Blennow to follow up Altland?'

TLDR: is Blennow "Mathematical Methods for Physics and Engineering" a good follow-up to Altland "Mathematics for physicists"? Hello everybody, returning to physics after 30-something years, I felt the need to brush up my maths first. It took me 6 months and I'm currently more than half way through the Altland "Mathematics for physicists" book, covering the math for undergraduate studies at the right level of sophystication, most of which I howewer already knew (being an aerospace engineer)...

Thread 'Books with a more theoretical approach to turbulence and DNS'

I've gone through the Standard turbulence textbooks such as Pope's Turbulent Flows and Wilcox' Turbulent modelling for CFD which mostly Covers RANS and the closure models. I want to jump more into DNS but most of the work i've been able to come across is too "practical" and not much explanation of the theory behind it. I wonder if there is a book that takes a theoretical approach to Turbulence starting from the full Navier Stokes Equations and developing from there, instead of jumping from...
