Topology of black hole thermodynamics via Rényi statistics
European Physical Journal C: Particles and FieldsIn this paper, we investigate the topological numbers of the four-dimensional Schwarzschild black hole, d-dimensional Reissner–Nordström (RN) black hole, d-dimensional singly rotating Kerr black hole and five-dimensional Gauss–Bonnet black hole via the ...

When Cubic is Not Isotropic: Phonon–Exciton Decoupling in CuInSnS4 Single Crystals
Advanced Optical Materials, EarlyView.A cubic CuInSnS4 crystal does not fully play by cubic rules. While phonons follow the average iso‐tropic lattice symmetry, the disorder‐localized excitons break away, showing strong, and reproduci‐ble polarization‐dependent emission. This work shows how intrinsic cation disorder can turn a mac‐roscopically cubic material into a source of hidden ...

Self‐Powered Visible‐Blind Graphene/NiO/ZnO UV‐C Photodiodes
Advanced Optical Materials, EarlyView.“A scalable architecture for self‐powered UV‐C photodiodes integrates defect‐engineered p‐NiO/n‐ZnO heterojunctions with highly UV‐C transparent graphene anodes. The type‐II band alignment combined with the built‐in electrical field enables robust zero‐bias charge separation.

A Cardy-like formula for rotating black holes with planar horizon
Journal of High Energy Physics, 2017 We show that the semiclassical entropy of D−dimensional rotating (an)isotropic black holes with planar horizon can be successfully computed according to a Cardy-like formula.

Black hole entropy and models [PDF]
, 1997 No universally accepted statistical explanation of black hole entropy exists up to now, therefore, it is worth another try. Admittedly, black hole entropy does not have to have a statistical origin. If the "black hole entropy" is called "black hole index"

Negative horizon mass for rotating black holes
, 2006 Charged rotating black holes of Einstein–Maxwell–Chern–Simons theory in odd dimensions, D⩾5, may possess a negative horizon mass, while their total mass is positive.

Size and shape of rotating strings and the correspondence to black holes
Journal of High Energy PhysicsIn light of the correspondence between black holes and fundamental strings with non-zero spin, we compute the sizes of rotating strings for small, moderate, and large values of the angular momentum and compare them to the sizes of rotating black holes ...

On black holes in string theory
, 2011 PhDThis thesis investigates black holes in string theory through string amplitudes and through gauge-gravity duality. The research presented in this thesis supports the claim that string theory is capable of a consistent quantum-mechanical description

Advanced Robotics Research, EarlyView.Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.
