Plasma broadening of autoionizing resonances

, 2023
A general formulation is developed to demonstrate that atomic autoionizing (AI) resonances are broadened and shifted significantly due to plasma effects across bound-free continua. The theoretical and computational method presented accounts for broadening mechanisms: electron collisional, ion microfields (Stark), thermal Doppler, core excitations, and ...

Enhanced Ultrasound Transmission Through Aberration Layers Using Space‐Coiling Acoustic Metamaterials

Advanced Engineering Materials, EarlyView.
Enhancing ultrasound transmission through an aberration layer exhibiting mismatched impedance with the surrounding medium possesses great implications in imaging and treatment. In this study, we show that a space‐coiling acoustic metamaterial with judiciously tailored structural profile can help improve impedance matching.

Ferromagnetic resonance linewidth and two-magnon scattering in Fe1-xGdx thin films

AIP Advances, 2017
Magnetization dynamics of Fe1-xGdx thin films (0 ≤ x ≤ 22%) has been investigated by ferromagnetic resonance (FMR). Out-of-plane magnetic field orientation dependence of resonance field and linewidth has been measured.

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

Advanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

Inferring astrophysical neutrino sources from the Glashow resonance

Journal of High Energy Physics, 2023
We infer the ultrahigh energy neutrino source by using the Glashow resonance candidate event recently identified by the IceCube Observatory. For the calculation of the cross section for the Glashow resonance, we incorporate both the atomic Doppler ...

Irradiation‐Induced Spin Bath Evolution and as‐Grown Hydrogen Defects in CVD Diamond Revealed by NV‐Based DEER Spectroscopy

Advanced Functional Materials, EarlyView.
Here, we provide the reader with the current state of the art in the fabrication of high‐T2‐coherence diamond, optimized through the use of double electron–electron resonance (DEER) spectroscopy. We reveal the main as well as yet unidentified spin defects, the reduction of which is essential for reducing the spin bath and fabricating materials for ...

Ferromagnetic resonance spectra of Py deposited on (Bi1-xSbx)2Te3

AIP Advances, 2017
We measure ferromagnetic resonance spectra of sputtered Py (20 nm) on (Bi1-xSbx)2Te3 (∼50 nm, x = 0-1) grown by molecular beam epitaxy. The linewidths of the spectra for Py on (Bi1-xSbx)2Te3 are much broader than that of Py directly deposited on a flat ...

The radial fine structure caused by kinetic passing electrons in the ion-temperature-gradient mode [PDF]

AIP Advances
The radial fine structure (RFS) near the mode rational surface (MRS) in the ion-temperature-gradient mode due to passing electrons is investigated. The gyrokinetic equation of passing electrons near the MRS is derived, revealing that parallel resonance ...

Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene

Advanced Functional Materials, EarlyView.
Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...

Unusual Evolutions of Dissipative-Soliton-Resonance Pulses in an All-Normal Dispersion Fiber Laser

IEEE Photonics Journal, 2019
We experimentally report the novel evolutions of dissipative-soliton-resonance (DSR) pulses with respect to the pump power in an all-normal-dispersion fiber laser based on a nonlinear optical loop mirror.
