Quantum Theory of Many-Particle Systems by Alexander L. Fetter and John Dirk Walecka is widely considered the gold-standard textbook for introducing graduate students to the complexities of many-body physics. Since its original publication in 1971, it has served as a critical bridge between standard introductory quantum mechanics and the advanced research literature in condensed matter and nuclear physics.
