Spectroscopy of quantum-corrected Schwarzschild black hole

open access: yesNuclear Physics B, 2019
The quantization of black hole parameters is a long-standing topic in physics. Adiabatic invariance, periodicity of outgoing waves, quantum tunneling, and quasi-normal modes are the typical tools via which the area and the entropy of a black hole are ...

Multimode Oxide‐Based Optoelectronic Memtransistor for In‐Sensor Vision Processing

open access: yesAdvanced Functional Materials, EarlyView.
A multimode optoelectronic memtransistor (OEMT) is demonstrated for vision explainable artificial intelligence (VXAI) hardware. By integrating optical sensing, electrical masking, and non‐volatile memory, the device enables key operations required for generating saliency information.

Hawking radiation in dispersive media [PDF]

open access: yes, 2011
Hawking radiation, despite its presence in theoretical physics for over thirty years, remains elusive and undetected. It also suffers, in its original context of gravitational black holes, from conceptual difficulties.

Mechanistic Control of C─H Bond Activation and C─C Coupling in Light‐Driven Methane Conversion to C2+ Products over Multifunctional Photocatalysts

open access: yesAdvanced Functional Materials, EarlyView.
Methane photocatalytic activation under mild conditions remains a formidable challenge in the synthesis of solar fuels. In this review, we emphasize the growing importance of multifunctional materials and hybrid systems within a unified mechanistic framework that integrates selective C─H bond activation, formation and control of intermediates, C─C ...

Bayesian Black Hole Photogrammetry

open access: yesThe Astrophysical Journal
We propose an analytic dual-cone accretion model for horizon-scale images of the cores of low-luminosity active galactic nuclei, including those observed by the Event Horizon Telescope (EHT).

Chemically Fueled Systems Chemistry Across Length Scales

open access: yesAdvanced Functional Materials, EarlyView.
Chemically fueled reaction cycles regulate processes through single and multiple catalytic sites on the molecular and assembly scale. This gives rise to unique kinetically controlled properties/functions like spatio‐temporal catalysis, oscillations, optical properties, and perform work.

A Holographic View on Physics out of Equilibrium

open access: yesAdvances in High Energy Physics, 2010
We review the recent developments in applying holographic methods to understand nonequilibrium physics in strongly coupled field theories. The emphasis will be on elucidating the relation between evolution of quantum field theories perturbed away from ...

Polarization‐Dependent Synaptic‐Like Electro‐Optical Response in Ferroelectric Nematic Liquid Crystals

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectric nematic liquid crystals (FNLCs) offer fast, tunable polarization and low‐voltage operation but suffer from poor polarization retention at zero field. Semiconductor‐modified FNLCs enhance polarization retention and exhibit short‐ and long‐term electro‐optical responses, while also supporting spike‐type signal integrations.
