Effective Field Theory for Dilute Fermi Systems
The virtues of an effective field theory (EFT) approach to many-body problems are illustrated by deriving the expansion for the energy of an homogeneous, interacting Fermi gas at low density and zero temperature. A renormalization scheme based on dimensional regularization with minimal subtraction leads to a more transparent power-counting procedure and diagrammatic expansion than conventional ...

متن کاملDilute neutron matter on the lattice at next-to-leading order in chiral effective field theory
We discuss lattice simulations of the ground state of dilute neutron matter at nextto-leading order in chiral effective field theory. In a previous paper the coefficients of the next-to-leading-order lattice action were determined by matching nucleon-nucleon scattering data for momenta up to the pion mass. Here the same lattice action is used to simulate the ground state of up to 12 neutrons in...
متن کاملEffective Field Theory and the Fermi Surface
This is an introduction to the method of effective field theory. As an application, I derive the effective field theory of low energy excita-tions in a conductor, the Landau theory of Fermi liquids, and explain why the high-T c superconductors must be described by a different effective field theory. Lectures presented at TASI 1992.
متن کاملGround state energy of dilute neutron matter at next-to-leading order in lattice chiral effective field theory
We present lattice calculations for the ground state energy of dilute neutron matter at next-to-leading order in chiral effective field theory. This study follows a series of recent papers on low-energy nuclear physics using chiral effective field theory on the lattice. In this work we introduce an improved spinand isospin-projected leading-order action which allows for a perturbative treatment...
