A Possible Mechanism for the Low Shear Viscosity in the QGP Created by RHIC
I. Giannakis, Defu Hou, Jia-rong Li +1
We study the Anderson Localization effect on the shear viscosity in a system with random medium by Kubo formula. We show that this effect can reduce the shear viscosity nonperturba…
Inhomogeneity driven by Higgs instability in gapless superconductor
Ioannis Giannakis, Defu Hou, Mei Huang +1
The fluctuations of the Higgs and pseudo Nambu-Goldstone fields in the 2SC phase with mismatched pairing are described in the nonlinear realization framework of the gauged Nambu--J…
Higgs instability in gapless superfluidity/superconductivity
Ioannis Giannakis, Defu Hou, Mei Huang +1
In this letter we explore the Higgs instability in the gapless superfluid/superconducting phase. This is in addition to the (chromo)magnetic instability that is related to the fluc…
Absence of the London limit for the first-order phase transition to a color superconductor
Jorge L. Noronha, Hai-cang Ren, Ioannis Giannakis +2
We study the effects of gauge-field fluctuations on the free energy of a homogeneous color superconductor in the color-flavor-locked (CFL) phase. Gluonic fluctuations induce a stro…
A Neutral Two Flavor Loff Color Superconductor
Ioannis Giannakis, De-fu Hou, Hai-Cang Ren
In this paper we construct analytically a LOFF color superconducting state that is both color and charge neutral using the weak coupling approximation. We demonstrate that this sta…
Chromomagnetic Instability and the LOFF state in a two flavor Color Superconductor
Ioannis Giannakis, Hai-Cang Ren
We explore the relation between the chromomagnetic instability of a homogeneous two flavor color superconductor and the LOFF state. We perturb the free energy of the 2SC by generat…
