Effective Field Theories, Landau-Migdal Fermi-Liquid Theory and Effective Chiral Lagrangians for Nuclear Matter∗
We reinterpret Landau-Migdal Fermi-liquid theory of nuclear matter as an effective chiral field theory with a Fermi surface. The effective field theory is formulated in terms of a chiral Lagrangian with its mass and coupling parameters scaling a la Brown-Rho and with the LandauMigdal parameters identified as the fixed points of the field theory. We show how this mapping works out for response f...
متن کاملNon-Fermi Liquid Effective Field Theory of Dense QCD Matter
where vμ = (1, ~v). The field ψv describes particles and holes with momenta p = μ(0, ~v)+k, where k ≪ μ. We will write k = k0 + k‖ + k⊥ with ~k‖ = ~v(~k · ~v) and ~k⊥ = ~k − ~k‖. L4f denotes four-fermion operators in the BCS and zero sound channel. At energies below the screening scale gμ hard dense loops have to be resummed. The generating functional for hard dense loops in gluon n-point funct...
متن کاملFrom Chiral Lagrangians to Landau Fermi Liquid Theory of Nuclear Matter
A simple relation between the effective parameters of chiral Lagrangians in medium as predicted by BR scaling and Landau Fermi liquid parameters is derived. This provides a link between an effective theory of QCD at mean-field level and many-body theory of nuclear matter. It connects in particular the scaling vector-meson mass probed by dileptons produced in heavy-ion collisions (e.g., CERES of...
متن کاملDense Nuclear Matter: Landau Fermi-Liquid Theory and Chiral Lagrangian with Scaling
The relation between the effective chiral Lagrangian whose parameters scale according to Brown and Rho scaling(“BR scaling”) and Landau Fermi-liquid theory for hadronic matter is discussed in order to make a basis to describe the fluctuations under the extreme condition relevant to neutron stars. It is suggested that BR scaling gives the background around which the fluctuations are weak. A simp...
متن کاملEffective field theory for nuclear matter
We apply the relativistic chiral Lagrangian to the nuclear equation of state. An effective chiral power expansion scheme, which is constructed to work around nuclear saturation density, is presented. The leading and subleading terms are evaluated and are shown to provide an equation of state with excellent saturation properties. Our saturation mechanism is found to probe details of the nuclear ...
