localhost (One-dimensional model of CFT)

In theoretical physics, the "localhost" (often called the "one-dimensional model" of a conformal field theory or CFT) refers to a simplified framework where a complex, highly symmetrical quantum system is studied on a single line or circle. Imagine modeling a universe of particles constrained to move along a single loop or straight line, capturing many of its essential properties. This approach helps physicists understand fundamental behaviors like scale invariance and interactions in a manageable setting, providing insights that can be extended to higher-dimensional, more complicated theories in quantum physics and string theory.
