Life‐Like Ferrous Oxide Microspheres from Kombucha
Advanced Materials Interfaces, EarlyView.Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.

Advanced Optical Materials, EarlyView.Low‐index and low‐loss vdW muscovite represents an emerging robust dielectric platform for the creation of next‐generation all‐vdW nanophotonic architectures. Its utilization as a low‐index building‐block in all‐vdW multilayers enables extreme optical contrast when paired with MoS2, paving the way to the realization of few‐layer ultrathin DBS ...

Kramers-Kronig relations for nonlinear optics
Electronics Letters, 1990 The exact relationships between the real and imaginary parts of the susceptibility of nonlinear optical materials are reported. The implications of this result in the context of semiconductor lasers and to the study of nonlinear semiconductor optical waveguides are indicated.

Dispersion relation for air via Kramers-Kronig analysis [PDF]
The Journal of the Acoustical Society of America, 2008 A general expression for the dispersion of acoustic waves in air is obtained by combining the attenuation coefficient given by the ISO:9613-1 standard and the twice-subtracted Kramers-Kronig relation. Good agreement is found with published data of sound velocity at different frequencies and relative humidities.

Advanced Science, EarlyView.High‐throughput screening led to the identification of 67 Z‐scheme heterojunctions (comprising 2D magnetic transition metal halides and non‐magnetic transition metal chalcogenides). For CrI3/MoTe2 and CrI3/WTe2, electronic structure analysis demonstrated that synergistic crystallographic point group and built‐in electric field effects generate a ...

Quantum dynamics of the damped harmonic oscillator
New Journal of Physics, 2012 The quantum theory of the damped harmonic oscillator has been a subject of continual investigation since the 1930s. The obstacle to quantization created by the dissipation of energy is usually dealt with by including a discrete set of additional harmonic

Advanced Science, EarlyView.Researchers developed and applied a generative artificial intelligence (AI) model to optimize epsilon‐near‐zero thin film stacks for ultra‐broadband perfect absorption of light. The fabricated AI‐designed absorber, with a total thickness of only 160 nm, experimentally demonstrated an absorption bandwidth exceeding 1000 nm while maintaining greater than

Is there a conflict between causality and diamagnetism?
New Journal of PhysicsThere is a long-standing apparent conflict between the existence of diamagnetism and causality as expressed through the Kramers–Kronig relations. In essence, using causality arguments, along with a small number of seemingly well-justified assumptions ...

Relativistic force between fast electrons and planar targets
New Journal of Physics, 2014 The full retarded electromagnetic force experienced by swift electrons moving parallel to planar boundaries is revisited, for both metallic and dielectric targets, with special emphasis on the consequences in electron microscopy experiments. The focus is
