Effective Field Theory of Neutron Star Superfluidity
James Hormuzdiar, Stephen Hsu
We apply effective field theory and renormalization group techniques to the problem of Cooper pair formation in neutron stars. Simple analytical expressions for the conden…
Non-Perturbative Couplings and Color Superconductivity
Nick Evans, Stephen Hsu, Myckola Schwetz
Quark matter at sufficiently high density exhibits color superconductivity, due to attractive gluonic interactions. At lower densities of order , it has been proposed th…
An Effective Field Theory Approach to Color Superconductivity at High Quark Density
Nick Evans, Stephen D. H. Hsu, Myckola Schwetz
We investigate the Fermi Liquid theory of high density QCD. Using the renormalization group (RG), we determine the behavior of effective fermion interactions near the Fermi surface…
Pion Breather States in QCD
James N. Hormuzdiar, Stephen D. H. Hsu
We describe a class of pionic breather solutions (PBS) which appear in the chiral lagrangian description of low-energy QCD. These configurations are long-lived, with lifetimes grea…
On the QCD Phase Transition at Finite Baryon Density
Stephen D. H. Hsu, Myckola Schwetz
We investigate the QCD chiral phase transition at finite chemical potential , using the renormalization group (RG) to characterize the infrared behavior of sigma models constrai…
Isospin Fluctuations from Multiple Domains of Disoriented Chiral Condensate
James Hormuzdiar, Stephen D. H. Hsu
We describe some detailed numerical simulations of Disoriented Chiral Condensates (DCCs), using the chiral lagrangian as a controlled long-wavelength description. We focus on the p…
