Effective Field Theory Power Counting at Finite Density
Effective field theory is applied to finite-density systems with two-particle interactions exhibiting an unnaturally large scattering length, such as neutron matter. A new organizational scheme, identified for a large number of spacetime dimensions, allows for convergent analytic calculations in many-body systems and is similar to the hole-line expansion of traditional nuclear physics. PACS num...
متن کاملQcd at Finite Density
At sufficiently high temperature and density, quantum chromodynamics (QCD) predicts phase transition from the hadronic phase to the quark-gluon plasma phase. Lattice QCD is the most useful tool to investigate this critical phenomenon, which status is briefly reviewed. The usual problem in the Lagrangian formulation at finite density is either an incorrect continuum limit or its complex action a...
متن کاملQCD thermodynamics at finite density
Recent progress in extending finite temperature lattice QCD simulations from the T axis into the finite density plane is reviewed. The covered topics are a calculation of the transition line by multidimensional reweighting, screening mass calculations in dimensionally reduced QCD and simulations at imaginary μ.
متن کاملLattice QCD at finite density
I discuss different approaches to finite density lattice QCD. In particular, I focus on the structure of the phase diagram and discuss attempts to determine the location of the critical end-point. Recent results on the transiton line as function of the chemical potential (Tc(μq)) are reviewed. Along the transition line, hadronic fluctuations have been calculated, which can be used to characteri...
متن کاملHadronic property at finite density
Lattice QCD simulations at finite chemical potential μ are extremely difficult due to the sign problem. Recently it has been realized that at small chemical potential one can study density effects on physical quantities by various approaches.1) One of the approaches is the derivative method which has been used for the study of response of meson masses with respect to μ by QCD-TARO collaboration...
