Making the Great Desert Bloom
Jacques Distler, Andreas Karch
The absence of new physics beyond neutrino masses between the weak scale and the Planck scale is referred to as the great desert. It is often seen as a nightmare scenario for parti…
Quantum Complexity Dynamics for Disjoint Subsystems
Yale Fan, Nicholas Hunter-Jones, Andreas Karch +2
Quantum complexity has emerged as a natural probe of chaos, thermalization, and the black hole interior on timescales long after local observables have equilibrated. However, its t…
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…
Universality of Effective Central Charge in Interface CFTs
Andreas Karch, Yuya Kusuki, Hirosi Ooguri +2
When an interface connects two CFTs, the entanglement entropy between the two CFTs is determined by a quantity called the effective central charge. The effective central charge doe…
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…
