= Gaussian fixed point
{wiki=Gaussian_fixed_point}
The Gaussian fixed point is a concept from the field of statistical physics and quantum field theory, particularly in the context of renormalization group (RG) flows. It refers to a fixed point in the space of coupling constants where the theory becomes independent of the details of the underlying microscopic structure at large length scales. Here’s a deeper explanation: \#\#\# Background In many physical systems, particularly those near critical points or phase transitions, the behavior of the system can be described using field theories.
