Effect of gauge-field fluctuations on the phase transition between normal and color-superconducting quark matter
Jorge L. Noronha, Hai-cang Ren, Ioannis Giannakis +2
Type-I color superconductors display a first-order phase transition due to thermal gauge-field fluctuations. We numerically evaluated the critical temperature of the first-order ph…
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…
The Meissner Effect in a Two Flavor LOFF Color Superconductor
Ioannis Giannakis, Hai-Cang Ren
We calculate the magnetic polarization tensor of the photon and of the gluons in a two flavor color superconductor with a LOFF pairing that consists of a single plane wave. We show…
Symmetry Breaking in String Theory
Ioannis Giannakis
In this paper we discuss symmetry breaking in string theory. Spacetime symmetries are implemented as inner automorphisms of the underlying superconformal algebra. Conserved current…
SuperHiggs Mechanism in String Theory
Jonathan Bagger, Ioannis Giannakis
We exhibit the superHiggs effect in heterotic string theory by turning on a background NS-NS field and deforming the BRST operator consistent with superconformal invariance. The NS…
