Description
The fixed points of the renormalization group flow are crucial for classifying phases of matter and understanding their universal low-energy physics. In metals, however, fixed points are defined only projectively due to the indefinite growth of Fermi momentum under scale transformations. In this talk, I will discuss the physical implications of the projective nature of metallic fixed points and the recent progress made in charting the space of universality classes for non-Fermi liquids.
