Non-Fermi liquid fixed point in a Wilsonian theory of quantum critical metals

Understand

We study the problem of disorder-free metals near a continuous quantum critical point.

• We depart from the standard paradigm of Hertz and Millis, and treat both fermions and bosons i.e.
• order parameter fields) on equal footing.
• We construct a Wilsonian effective field theory that integrates out only high energy boson and fermion modes.
