The phases of deuterium at extreme densities
Paulo F. Bedaque, Michael I. Buchoff, Aleksey Cherman
We consider deuterium compressed to higher than atomic, but lower than nuclear densities. At such densities deuterium is a superconducting quantum liquid. Generically, two supercon…
Sommerfeld enhancement from Goldstone pseudo-scalar exchange
Paulo F. Bedaque, Michael I. Buchoff, Rashmish K. Mishra
We point out that the exchange of a Goldstone pseudo-scalar can provide an enhancement in the dark matter annihilation rate capable of explaining the excess flux seen in high energ…
Meson Masses in High Density QCD
Silas R. Beane, Paulo F. Bedaque, Martin J. Savage
The low-energy effective theories for the two- and three-flavor color-superconductors arising in the high density limit of QCD are discussed. Using an effective field theory to des…
Color Superconductivity in Asymmetric Matter
Paulo F. Bedaque
The influence of different chemical potential for different flavors on color superconductivity is analyzed. It is found that there is a first order transition as the asymmetry grow…
Cutting rules at finite temperature
P. F. Bedaque, A. Das, S. Naik
We discuss the cutting rules in the real time approach to finite temperature field theory and show the existence of cancellations among classes of cut graphs which allows a physica…
Chiral perturbation theory analysis of baryon temperature mass shifts
Paulo F. Bedaque
We compute the finite temperature pole mass shifts of the octet and decuplet baryons using heavy baryon chiral perturbation theory and the 1/N_c expansion, where N_c is the number…
