Free Quantum Mechanics Book – Quantum Mechanics: A Physical Approach (CUP)

I just came across a newly released Quantum Mechanics textbook by Ana María Cetto and Luis de la Peña: Quantum Mechanics: A Physical Approach.

For those familiar with de la Peña’s earlier work (Introduction to Quantum Mechanics), this feels like a natural continuation and content expansion. The book maintains a strong physical perspective - as its name indicates - while developing the formalism in a rigorous but accessible way.

One particularly valuable aspect is that it comes with a 400-page solutions manual covering exercises from each chapter, which makes it especially useful for self-study or teaching.

Even better, both the textbook and the full solutions manual are available for free download directly from Cambridge University Press.

You can find it by searching the title on the Cambridge University Press website. Or at this link https://www.cambridge.org/core/books/quantum-mechanics/EDC2EFA0B46C4D3CC69DA183F24620E5

I thought this might be useful for students and anyone interested in a physically motivated approach to QM, as me.

Thank you, do you also have the link to the solutions manual? I can't seem to find it.

The link is in the last page of the preface: https://www.cambridge.org/cetto-delapena

I found the solutions pdf under the resources tab on that page.

I think the fact that they made it open access is amazing! I never went through his other books but my friends swear they are amazing, probably this one isn't any different

This may just overthrow Sakuria

Sakurai is great, we'll see if he can be overthrown
