Intraoral Coil Arrays for Single‐Tooth Dental MRI
ABSTRACT Purpose MRI offers superior contrast to x‐ray and CBCT that can play an important role in diagnosing dental pathologies. Current extraoral RF coils for MRI in dentistry provide only limited SNR, thus limiting spatial resolution. We propose an intraoral coil (IOC) array that can provide high SNR to achieve a 250 μm isotropic resolution and ...

Probing Ultrafast Coherent Bandgap Modulation in Monolayer WSe2 by Nonlinear Optics
This work sheds light on how resonant nonlinear optics blursthe line between perturbative and non‐perturbative nonlinear optics. Measured deviationsfrom the quadratic second‐harmonic scaling near the excitonic resonance arisefrom optical Stark and Bloch‐Siegert shifts. The experimental results arefurther underpinned by analytical and numerical analysis

A local‐to‐nonlocal SHG process is demonstrated on an electrically tunable metasurface, combining an LSPR at the FF with a TM‐GMR at the SH to achieve independent dual tunability. Through modal‐overlap engineering of the proposed scheme, a high‐χ(2) MQW meta‐atom delivers strong nonlinearity while achieving 2‐DoF SH control with minimal trade‐offs ...

A uniform torsion field—representing a controlled density of parallel screw dislocations—confines a single electron into a geometry‐defined quantum dot. In a perpendicular magnetic field, an Aharonov–Bohm flux breaks the m↔−m$m \leftrightarrow -m$ symmetry and yields a flux‐ and torsion‐tunable angular pseudospin (m=±1)$(m = \pm 1)$ with asymmetric ...

Decoherence of a charge qubit is usually credited to charge noise in the environment. Here we show that charge noise may not be the limiting factor for the qubit coherence.

Self‐Creation of Accelerated Temporal Mirrors
The field of temporal analog effects is rapidly emerging and seen as a driver of a paradigm shift in photonics. It promises striking new phenomena but remains experimentally challenging. This work introduces a mechanism that automatically creates a temporal mirror with simple optical means, unlocking practical access to extreme nonlinear dynamics and ...

Experimental and Computational Raman and SERS Study of Acid Blue 113
The vibrational features of AB‐113 were investigated through experimental and theoretical analyses. SERS spectra showed enhanced responses under resonant excitation, especially at 532 and 632.8 nm, enabling identification limits as low as 1.0 × 10−8 mol L−1.

Quantum Theory of Surface Lattice Resonances
ABSTRACT The collective interactions of nanoparticles arranged in periodic structures give rise to high‐Q $Q$ in‐plane diffractive modes known as surface lattice resonances. Although these resonances and their broader implications have been extensively studied within the framework of classical electrodynamics and linear response theory, a quantum ...
