A bstract We study how the black hole complementarity principle can emerge from quantum gravitational dynamics within a local semiclassical approximation. Further developing and then simplifying microstate model based on fragmentation instability of near-extremal hole, we find that key to replication (but not cloning) infalling information is decoupling various degrees freedom. The matter decouples interior retaining residual time-dependent state in hair which encodes initial...
Black holes past their Page times should act as efficient scramblers and information mirrors. The of the infalling bits are rapidly encoded by old black hole in Hawking quanta, but it take time that is exponential entropy to decode interior. Motivated features fragmentation instability near-extremal holes, we construct a simple phenomenological model lattice interacting nearly $AdS_2$ throats with gravitational hair charges propagating over lattice. We study microstate solutions response...
Semi-holography, originally proposed as a model for conducting lattice electrons coupled to holographic critical sector, leads an effective theory of non-Fermi liquids with only few relevant interactions on the Fermi surface in large $N$ limit. A refined version such theories has two couplings which give and Fermi-liquid-like contributions self-energy, respectively. We show that low co-dimension sub-manifold exists space semi-holographic strange metallic behavior is manifested, can be...

A refined semi-holographic non-Fermi liquid model, in which carrier electrons hybridize with operators of a holographic critical sector, has been proposed recently for strange metallic behavior. The consistently effective theory approach, two couplings whose ratio is related to the doping. We explain origin linear-in-T resistivity and behavior as consequence emergence universal form spectral function independent model parameters when take optimal values determined only by exponent. This fits...
