AdS Higgs mechanism from double trace deformed CFT
Andreas Karch, Mianqi Wang, Merna Youssef
Explicit breaking of a global symmetry in a conformal field theory is holographically dual to giving mass to a gauge field living in AdS via the Higgs mechanism. We show that if th…
Constraining braneworlds with entanglement entropy
Hao Geng, Andreas Karch, Carlos Perez-Pardavila +4
We propose swampland criteria for braneworlds viewed as effective field theories of defects coupled to semiclassical gravity. We do this by exploiting their holographic interpretat…
Subregion Entropy for the Doubly Holographic Global Black String
Andreas Karch, Carlos Perez-Pardavila, Marcos Riojas +1
We study the growth of entanglement entropy in a doubly holographic model of gravity for a spherical AdS black hole. Compared to previous work, which was limited to the case of pla…
