Decoding infrared imprints of quantum origins of black holes

Physics Letters B, 2019
We analyze the emission spectrum of a (fundamentally quantum) black hole in the Kerr–Newman family by assuming a discretization of black hole geometry and the holographic entropy–area relation. We demonstrate that, given the above structure of black hole

Micropatterned Biphasic Printed Electrodes for High‐Fidelity on‐Skin Bioelectronics

Advanced Functional Materials, EarlyView.
Micropatterned biphasic printed electrodes achieve unprecedented skin conformity and low impedance by combining liquid‐metal droplets with microstructured 3D lattices. This scalable approach enables high‐fidelity detection of ECG, EMG, and EEG signals, including alpha rhythms from the forehead, with long‐term comfort and stability.

Flux‐Regulated Crystallization of Perovskites Using Machine Learning‐Predicted Solvent Evaporation Rates for X‐Ray Detectors

Advanced Functional Materials, EarlyView.
By integrating machine learning into flux‐regulated crystallization (FRC), accurate prediction of solvent evaporation rates in real time, improving crystallization control and reducing crystal growth variability by over threefold, is achieved. This enhances the reproducibility and quality of perovskite single crystals, leading to reproducible ...

Late-time saturation of black hole complexity

Journal of High Energy Physics
The holographic complexity of a static spherically symmetric black hole, defined as the volume of an extremal surface, grows linearly with time at late times in general relativity.

Early scrambling and capped BTZ geometries

Journal of High Energy Physics, 2019
Geodesic probes in certain horizonless microstate geometries experience extreme tidal forces long before reaching the region where these geometries differ significantl from the extremal BTZ black hole.

Certain Extremal Problems on a Classical Family of Univalent Functions

Mathematics
Consider the collection A of analytic functions f defined within the open unit disk D, subject to the conditions f(0)=0 and f′(0)=1. For the parameter λ∈[0,1), define the subclass R(λ) as follows:R(λ):=f∈A:Ref′(z)>λ,z∈D.

Ladder‐Type Benzene‐Perylene Dyes with Efficient Laser Properties in the Near‐IR by Detracting/Activating Low/High Frequency Vibronic Modes

Advanced Functional Materials, EarlyView.
The NNR‐n series of oligomeric nanographenes delivers exceptional emission performance. This work shows that this performance is originated by their ladder‐type structure, which effectively deactivates low‐frequency vibronic modes. This deactivation neglects the main pathway for non‐emissive deactivation, even in the near‐infrared region. The potential
