Magnetic catalysis with massive dynamical flavours
Johanna Erdmenger, Veselin G. Filev, Dimitrios Zoakos
Within gauge/gravity duality, we construct a backreacted supergravity background dual to SU(Nc) N=4 SYM coupled to Nf massive fundamental flavours in the presence of an external ma…
Real and Virtual Bound States in Lüscher Corrections for CP3 Magnons
Michael C. Abbott, Inês Aniceto, Diego Bombardelli
We study classical and quantum finite-size corrections to giant magnons in AdS_4 x CP^3 using generalised Lüscher formulae. Lüscher F-terms are organised in powers of the exponenti…
Spinning Conformal Blocks
Miguel S. Costa, Joao Penedones, David Poland +1
For conformal field theories in arbitrary dimensions, we introduce a method to derive the conformal blocks corresponding to the exchange of a traceless symmetric tensor appearing i…
TBA, NLO Luscher correction, and double wrapping in twisted AdS/CFT
Changrim Ahn, Zoltan Bajnok, Diego Bombardelli +1
The ground-state energy of integrably-twisted theories is analyzed in finite volume. We derive the leading and next-to-leading order (NLO) Lüscher-type corrections for large volume…
Generalized sine-Gordon solitons
C. dos Santos, D. Rubiera-Garcia
In this paper we construct analytical self-dual soliton solutions in (1+1) dimensions for two families of models which can be seen as generalizations of the sine-Gordon system but…
The cosmological evolution of p-brane networks
L. Sousa, P. P. Avelino
In this paper we derive, directly from the Nambu-Goto action, the relevant components of the acceleration of cosmological featureless -branes, extending previous analysis based…
