Homogeneous power counting in Non-Relativistic QCD with the velocity renormalization group (vNRQCD) necessitates the existence of both soft and ultrasoft gluons. We show that vNRQCD operators involving soft fields can be put in a manifestly gauge invariant form by exploiting gauge invariant gluon building blocks. These building blocks contain Wilson lines and are analogous to those used in...

In this talk I will discuss how ideas from SCET can be utilized in the
context of Fermi liquids. In particular I will discuss the case of the Hubbard model at half filling where the presence of singular points on the Fermi surface force the EFT to be modal with soft and collinear IR fields.
