An Unruh-DeWitt detector interacting with a position-superposed BTZ black hole produces outcome probabilities containing a nonclassical contribution that distinguishes quantum superposition from classical mixtures, arising from singularities in the probed spectrum.

Fuzzball models with stretched horizons modify or eliminate entanglement islands depending on boundary conditions and cap geometry, producing information paradox analogues in some cases.
In the Karch-Randall braneworld the zero-graviton-mass limit of the one-loop partition function is a massless graviton plus a decoupled massive vector, not the pure Randall-Sundrum II model.
At large central charge, BCFT von Neumann entropy with deformed boundaries is reproduced by island entropy in an emergent JT gravity setup with transparent boundary conditions set by the deformation.
Quantum soliton solutions in AdS3 are constructed via branes in 4D AdS C-metric, with negative-mass cases describing thermal CFT backreaction on global AdS3 and positive-mass cases replacing horizons with smooth origins.
Holographic complexity of CFTs in global dS_d is computed via volume and action prescriptions in AdS foliation and brane setups, then compared to results from static and Poincare patches.
Gauss-Bonnet corrections to the complete volume proposal introduce a competition effect in static black holes while preserving momentum-governed growth rates and logarithmic scrambling times in dynamical Vaidya geometries.
In a doubly holographic black hole model, the dimension of the microstate Hilbert space equals the sum of the quantum-corrected thermodynamic entropies of the left and right black holes, which equals the generalised entropy quantifying entanglement between the asymptotic boundaries.
