Many-body physics
Many-body physics studies systems with a large number of interacting particles, such as atoms in a solid or molecules in a gas. Unlike single-particle physics, where each particle's behavior can be understood independently, many-body physics explores how particles influence each other, leading to complex behaviors like superconductivity or magnetism. This field is crucial for understanding fundamental phenomena in condensed matter physics, materials science, and even quantum computing, where the collective behavior of particles plays a significant role in determining the properties of entire systems.

Many-body physics is a branch of physics that studies systems with a large number of interacting particles, like atoms in a solid or electrons in a metal. It explores how these interactions lead to complex behaviors and phenomena, such as magnetism, superconductivity, and phase transitions. The challenge arises because each particle influences and is influenced by many others, making the system's behavior difficult to predict. Researchers use mathematical models and computational techniques to analyze these interactions, contributing to our understanding of materials and informing advancements in technology, like semiconductors and quantum computing.
