The model of a Fermi surface coupled to gapless bosonic fluctuation (critical Fermi surface) plays a central role in modern condensed matter physics. The model appears in the descriptions of various quantum phases of matter, such as quantum spin liquid, half-filled Landau level, fermionic quantum criticality and strange metal. In this lecture series, I will discuss recent progress in this subject based on the Yukawa-SYK formulation of the critical Fermi surface problem.
