The discussion centers on recommendations for solid state physics textbooks, highlighting the need for both introductory and advanced resources. While Kittel's "Introduction to Solid State Physics" and Ashcroft & Mermin's "Solid State Physics" are commonly referenced, they are criticized for being outdated and not covering modern research topics. Alternative suggestions include Omar's "Elementary Solid State Physics" and Marder's "Condensed Matter Physics" for introductory material, and Philips & Phillips for more advanced study. The conversation also touches on the lack of contemporary solid state texts that effectively bridge quantum mechanics and quantum field theory, with participants expressing frustration over the abundance of quantum field theory resources compared to solid state physics. Economou's "The Physics of Solids—Essentials and Beyond" is praised for its clarity and systematic approach, making it a noteworthy modern option. The discussion emphasizes the importance of finding texts that align with current research and pedagogical needs in solid state physics.
