In summary, the conversation discusses recommendations for understanding limits and quantisation in non-relativistic quantum mechanics. The Landau and Lifgarbagez book is suggested as a good resource for explaining these concepts, specifically the chapter on Quasi-Classicality and the use of Bohr and Sommerfeld quantisation.

L&L do a good job of explaining Bohr and Sommerfeld quantisation which is what I think you're looking for when you say 'through the phase space stuff a little'.

Classical mechanics is a branch of physics that describes the motion and behavior of macroscopic objects, while quantum mechanics is a branch of physics that describes the behavior of microscopic particles. Classical mechanics follows deterministic laws, while quantum mechanics follows probabilistic laws.

Understanding the macro limit of quantum mechanics helps bridge the gap between the microscopic and macroscopic worlds. It also allows for a better understanding of how classical mechanics emerges from the underlying quantum laws.

An advanced undergrad/grad book for classical mechanics as macro limit of QM may cover topics such as Hamiltonian mechanics, Lagrangian mechanics, classical field theory, and the correspondence principle between classical and quantum mechanics.

Yes, prior knowledge of quantum mechanics is necessary to understand the macro limit of QM. A solid understanding of basic quantum principles and mathematical techniques is necessary to grasp the concepts covered in an advanced book on the macro limit of QM.

Understanding the macro limit of QM can have applications in other fields of science, such as condensed matter physics, astrophysics, and chemical physics. It can also provide insights into the behavior of complex systems and aid in the development of new technologies.
