Wilson loops on M2-branes and M5-branes
Author(s): Edward Quijada and Henrique Boschi-FilhoWe calculate configuration energies of stringlike membranes in M2- and M5-brane spaces. In the near horizon approximation these backgrounds reduce to...

Note on holographic nonrelativistic Goldstone bosons
Author(s): Riccardo Argurio, Andrea Marzolla, Andrea Mezzalira, and Daniel NaegelsWe consider a holographic setup where relativistic invariance is broken by a chemical potential, and a non-Abelian int...

String bits at finite temperature and the Hagedorn phase
Author(s): Charles B. ThornWe study the behavior of a simple string bit model at finite temperature. We use thermal perturbation theory to analyze the high temperature regime. But at low temperatures...

Nonminimal couplings in Randall-Sundrum scenarios
Author(s): G. Alencar, R. R. Landim, C. R. Muniz, and R. N. Costa FilhoIn this paper we propose a new way of obtaining a four-dimensional gauge invariant $U(n)$ gauge field from a bulk action. The res...
