Preserving Proton Resolution Under Cryogenic Dynamic Nuclear Polarization for Biomolecular Solid‐State NMR

Angewandte Chemie, EarlyView.
High‐resolution proton detection is preserved under cryogenic dynamic nuclear polarization (DNP) by combining fast MAS, extensive deuteration and selective methyl protonation. This strategy enables proton‐detected structural studies of biomolecular solids with enhanced sensitivity under DNP conditions.

Narrow linewidth, Q-switched erbium doped fibre laser

, 1996
We report a narrow linewidth, diode pumped, high power Q-switched Erbium doped fibre laser for the application of Landau-Placzek temperature sensing. An output coupler consisting of an in-fibre Bragg grating enables narrow linewidth operation.

Pressure‐Tuned Superconducting Dome and Persistent Charge‐Density‐Wave Order in NdSeTe2

Advanced Science, EarlyView.
NdSeTe2 exhibits an unusual pressure‐tuned phase diagram in which charge‐density‐wave order does not disappear at optimal superconductivity. Instead, Raman spectroscopy reveals a transformation from long‐range to short‐range correlations that remain invisible to resistivity and persist across the entire superconducting dome.

Advances and Applications of Narrow-Linewidth Vertical-Cavity Surface-Emitting Lasers

Photonics
Vertical-cavity surface-emitting lasers (VCSELs) have emerged as essential light sources for atomic-precision measurement, quantum-secure communication, high-speed optical transmission, and laser coherent scanning detection, owing to their low power ...

Narrow-Linewidth Microwave Generation Using a Self-Injected DBR Laser Diode

, 2009
A novel technique for generating narrow-linewidth microwave or millimeter-wave signals is proposed. In this scheme, a delayed self-injected distributed Bragg reflector laser diode, which is tuned by a low-frequency square-wave voltage, is used to ...

Exceptional Antimodes in Multi‐Drive Cavity Magnonics

Advanced Electronic Materials, EarlyView.
Driven‐dissipative cavity‐magnonics provides a flexible platform for engineering non‐Hermitian physics such as exceptional points. Here, using a four‐port, three‐mode system with controllable microwave interference, antimodes and coherent perfect extinction (CPE) are realized, enabling active tuning to antimode exceptional points.

Measurement technique for narrow-linewidth ferrimagnets

Electronics Letters, 1966
This proposed technique for narrow-linewidth measurement allows one to take into account the radiation-damping contribution to the observed linewidth. Therefore it is possible, considering this important interaction between the sample and circuit, to increase the measurement sensitivity and accuracy.

Machine Learning‐Assisted Design and Performance Prediction of a Compact Dual‐Band Polarization‐Insensitive THz Metamaterial Absorber for Skin‐Cancer‐Related Refractive‐Index Sensing

Advanced Electronic Materials, EarlyView.
A compact QASRR‐based THz metamaterial absorber enables polarization‐insensitive dual‐band absorption and skin‐cancer‐related refractive‐index sensing through measurable resonance shifts. Field, surface‐current, and circuit analyses clarify the dual‐resonance mechanism, while StackNet‐assisted prediction accurately estimates the simulated absorption ...

Engineering a Correlated Narrow‐Gap Semiconductor: Effects of Ga Substitution in EuZn2P2

Advanced Electronic Materials, EarlyView.
ABSTRACT The effect of Ga substitution on the electronic, magnetic, and low‐energy responses of the Zintl phase EuZn2P2${\rm EuZn}_2 {\rm P}_2$ is investigated by electrical transport, electron spin resonance (ESR), and terahertz time‐domain spectroscopy (THz‐TDS). Incorporating Ga into EuZn2P2${\rm EuZn}_2 {\rm P}_2$ (EuZn1.8Ga0.2P2${\rm EuZn}_{1.8} {\
