Quantum Many-Body Systems

Quantum many-body systems involve large groups of particles, like electrons or atoms, interacting according to quantum mechanics. These interactions lead to complex phenomena such as superconductivity and magnetism that cannot be understood by studying individual particles alone. Instead, scientists analyze the collective behavior of these particles, which requires advanced mathematical tools. Understanding these systems is essential for developing new materials, quantum computers, and exploring fundamental physics. Despite their complexity, studying quantum many-body systems reveals how macroscopic properties emerge from microscopic quantum interactions.
