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…
The Radion in the Karch-Randall Braneworld
Ioannis Giannakis, James T. Liu, Hai-cang Ren
In a braneworld context, the radion is a massless mode coupling to the trace of the matter stress tensor. Since the radion also governs the separation between branes, it is expecte…
Recovery of the Linearized 4D AdS and dS Schwarzschild Metric in the Karch-Randall Braneworld
Ioannis Giannakis
We present a linearized treatment of the Karch-Randall braneworld where an AdS_4 or dS_4 brane is embedded in AdS_5. We examine the quasi-zero graviton mode in detail and reproduce…
Linearized Gravity in the Karch-Randall Braneworld
Ioannis Giannakis, James T. Liu, Hai-cang Ren
We present a linearized gravity investigation of the bent braneworld, where an AdS_4 brane is embedded in AdS_5. While we focus on static spherically symmetric mass distributions o…
