A Holographic Open Quantum System
Ignacio Quiroz Vargas, Merna Youssef
We construct a holographic open quantum system by coupling two CFTs through a double trace deformation and tracing out the bath degrees of freedom within the Schwinger-Keldysh form…
Dissipation in Open Holography
Andreas Karch, Merna Youssef
We exploit the holographic realization of a conformal theory coupled to an external bath realized via a double trace deformation and its gravity dual in terms of transparent bounda…
The late time ramp from chord diagrams in the double-scaled SYK model
Amir Raz, Merna Youssef
We compute the ramp of the spectral form factor analytically from chord diagrams in double scaled SYK. We map the double-trace correlator to a sum of single trace two-point functio…
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…
