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…
Lightsheets, Branes and the Covariant Entropy Bound
Deog Ki Hong, Stephen D. H. Hsu
We investigate the geometry of lightsheets comprised of null geodesics near a brane. Null geodesics which begin parallel to a brane a distance d away are typically gravitationally…
Brane World Confronts Holography
Deog Ki Hong, Stephen D. H. Hsu
Holography principle imposes a stringent constraint on the scale of quantum gravity in brane-world scenarios, where all matter is confined on the brane. The thermodynamic ent…
Positivity and Fermionic Dense Matter
Deog Ki Hong, Stephen D. H. Hsu
Euclidean dense matter generically suffers from the fermion sign problem. However, we argue that the sign problem is absent if one considers only low-energy degrees of freedom. Spe…
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…
