RG analysis and Magnetic instability in gapless superconductors
Deog Ki Hong
We study the magnetic instability of gapless superconductors. The instability arises due to the infrared divergence associated with the gapless modes of the superconductor. When th…
The Roper and Radiative Decay of Pentaquarks
Deog Ki Hong
Identifying the Roper N(1440) and N(1710) as the pentaquark octet and anti-decuplet, respectively, we analyze their main decay modes in the diquark picture. The ratio of the partia…
Positivity of QCD at asymptotic density
Deog Ki Hong
In this talk, I try to show that the sign problem of dense QCD is due to modes whose frequency is higher than the chemical potential. An effective theory of quasi-quarks near the F…
Crystalline Color Superconductivity in Dense Matter
Deog Ki Hong
In this talk I discuss a recently proposed color superconducting phase of asymmetric quark matter where the up and down quark have different chemical potential, being in chemical e…
Critical couplings in Crystalline Color superconductivity
Deog Ki Hong, Y. J. Sohn
Solving the Schwinger-Dyson equations, we analyze the pairing of quarks in asymmetric quark matter where quarks have different chemical potentials. We show that in the asymmetric q…
Aspects of Color Superconductivity
Deog Ki Hong
I discuss some aspects of recent developments in color superconductivity in high density quark matter. I calculate the Cooper pair gap and the critical points at high density, wher…
