    Introductory Level

    • "Six Easy Pieces" by Richard Feynman: If you're new to physics altogether, this is a fantastic starting point. Feynman, a legendary physicist and communicator, introduces fundamental concepts in a clear and engaging way. It's not strictly a quantum mechanics book, but it lays a solid foundation for understanding the basic principles. The book covers atoms in motion, basic physics, the relation of physics to other sciences, energy, gravitation, and quantum behavior.

    • "Quantum Mechanics: The Theoretical Minimum" by Leonard Susskind and Art Friedman: Susskind is known for his clear and intuitive explanations of complex topics. This book is part of his "Theoretical Minimum" series, designed to teach you the essential concepts of quantum mechanics without overwhelming you with unnecessary details. It is aimed at undergraduates, or graduates who want to have an overview of the basic quantum mechanics. It provides the reader with all the information required to proceed to more advanced subjects.

    • "Principles of Quantum Mechanics" by R. Shankar: Considered as a standard textbook for an introductory quantum mechanics course. This book provides a comprehensive introduction to the principles of quantum mechanics. Shankar’s approach is mathematically rigorous but still accessible to students with a solid background in calculus and linear algebra. It starts with the experimental basis of quantum mechanics, covering topics such as wave-particle duality, the uncertainty principle, and the Schrödinger equation. This section builds a strong foundation for understanding the core concepts of quantum mechanics.

    Intermediate Level

    • "Quantum Mechanics" by David J. Griffiths: This is arguably the most popular textbook for undergraduate quantum mechanics courses. Griffiths' writing style is clear, concise, and engaging, making it a favorite among students. The book covers all the essential topics, from the Schrödinger equation and the hydrogen atom to perturbation theory and scattering. It is widely praised for its accessibility and its balanced approach to theory and applications. The book provides numerous examples and problems that allow students to practice applying the concepts they have learned. These problems range in difficulty from straightforward exercises to more challenging questions that require deeper understanding.

    • "Modern Quantum Mechanics" by J.J. Sakurai: A more advanced and mathematically rigorous treatment of quantum mechanics. Sakurai's book is known for its elegant presentation and its emphasis on symmetry principles. It's a great choice for students who want a deeper understanding of the mathematical formalism of quantum mechanics. Although it assumes the reader is already exposed to an introductory course of quantum mechanics, the topics are self-contained for the most part. Several topics of modern quantum mechanics that are usually not found in other textbooks are discussed in detail, such as Berry phase, quantum theory of measurements, and Bell's inequality.

    • "Quantum Mechanics, Volume 1" by Claude Cohen-Tannoudji, Bernard Diu, and Franck Laloë: This comprehensive textbook offers a detailed and in-depth exploration of quantum mechanics, covering a wide range of topics with clarity and precision. The book is structured into three main parts, beginning with a thorough introduction to the fundamental concepts and mathematical tools of quantum mechanics. This part covers wave-particle duality, the uncertainty principle, the Schrödinger equation, and the mathematical formalism necessary for describing quantum systems. It provides a solid foundation for understanding the more advanced topics discussed later in the book.

    Advanced Level

    • "Principles of Quantum Mechanics" by Paul Dirac: A classic text written by one of the pioneers of quantum mechanics. Dirac's book is known for its elegant and insightful treatment of the subject. It's a challenging read, but it offers a unique perspective on the foundations of quantum mechanics. It introduces the bra-ket notation, which is widely used in quantum mechanics. It presents a unified and elegant mathematical framework that simplifies complex calculations and provides deeper insights into quantum phenomena.

    • "Quantum Field Theory and the Standard Model" by Matthew D. Schwartz: For those interested in quantum field theory, this book provides a modern and comprehensive introduction to the subject. It covers the Standard Model of particle physics and the fundamental principles of quantum field theory. It is praised for its clear explanations and its focus on physical intuition, making it accessible to advanced students and researchers. It goes beyond traditional approaches by emphasizing effective field theory and renormalization group techniques, which are crucial for understanding modern particle physics. It presents these topics in a clear and pedagogical manner, making them accessible to students who are new to the field.

    • "Relativistic Quantum Mechanics" by Bjorken and Drell: A classic graduate text on relativistic quantum mechanics. This book is the second part of the series after Relativistic Quantum Fields. It delves into the application of quantum mechanics in systems where the speed of light is significant. This comprehensive book covers the one-particle problem and the many-particle problem, discussing various theoretical tools for calculations, such as Feynman's rules and others.
