Entering the Strong Coupling Regime in Conventional Organic Solar Cells
Advanced Functional Materials, EarlyView.Organic solar cells convert light into fossil‐free energy, yet they still cannot compete with their silicon counterparts. Strong exciton‐photon coupling can ameliorate some properties of organic solar cells, but it requires additional mirrors that diminish light absorbance. Here, mirror‐free strong exciton‐photon coupling is implemented in conventional

Fluid-membrane descriptions of various black holes
European Physical Journal C: Particles and FieldsThe membrane paradigm of black holes is an effective theory that replaces the event horizon with a fictitious yet tangible fluid. It has provided us with valuable insights, especially in understanding the environment of black holes.

Hawking radiation power equations for black holes
Nuclear Physics B, 2017 We derive the Hawking radiation power equations for black holes in asymptotically flat, asymptotically Anti-de Sitter (AdS) and asymptotically de Sitter (dS) black holes. This is done by using the greybody factor for these black holes.

Nuclear Physics B, 1986 Abstract We give a new derivation for the properties of radiation appearing to an observer bounded in a space-time domain that has a horizon; this includes the Rindler case (constant accelerating frame) and the Schwarzschild solution (black hole). Because of the global nature of the quantum state, which inevitably extends to space beyond the horizon,

Bright Monocompound Metal Halide Scintillator for Fast Neutron Radiography
Advanced Functional Materials, EarlyView.Metal halide scintillator, tetraphenylphosphonium manganese bromide (TPP2MnBr4), provides a significant benefit for fast neutron imaging. A fourfold increase in efficiency over traditional zinc sulfide screens is achieved by efficiently utilizing neutron interactions within its homogeneous structure.

Topological dyonic black holes of massive gravity with generalized quasitopological electromagnetism
European Physical Journal C: Particles and FieldsIn this paper we investigate new dyonic black holes of massive gravity sourced by generalized quasitopological electromagnetism in arbitrary dimensions. We begin by deriving the exact solution to the field equations defining these black holes and look at

Entropy bound of horizons for charged and rotating black holes
Physics Letters B, 2015 We revisit the entropy product, entropy sum and other thermodynamic relations of charged and rotating black holes. Based on these relations, we derive the entropy (area) bound for both event horizon and Cauchy horizon.

Powerful jets from accreting black holes: evidence from the optical and infrared
, 2010 A common consequence of accretion onto black holes is the formation of powerful, relativistic jets that escape the system. In the case of supermassive black holes at the centres of galaxies this has been known for decades, but for stellar-mass black ...
