Ultrafast Control of Coherent Acoustic Lattice Dynamics in the Transition Metal Dichalcogenide Alloy WSSe

Advanced Physics Research, EarlyView.
Coherent acoustic phonons are generated and optically controlled in bulk WSSe alloy samples using ultrafast spectroscopy. The alloy exhibits a strong coherent acoustic response, which is not an intermediate state between WS? and WSe?. Instead, a much more complex mechanism is proposed.

Toroidal‐Dipole‐Driven Polarization‐Selective Quasi‐BICs Enabling Wide‐Angle Near‐Field Image Display in Dielectric Metasurfaces

Advanced Physics Research, EarlyView.
This study presents toroidal‐dipole (TD)‐driven polarisation‐selective quasi‐bound states in the continuum (quasi‐BICs) in all‐dielectric metasurfaces, enabling transverse magnetic (TM)‐selective excitation with ultrahigh quality factors and wide‐angle‐stable polarisation‐dependent near‐field imaging.

The Progress of Orbitronics: The Enhancement of Orbital Torque Efficiency

Advanced Physics Research, EarlyView.
Orbit‐torque (OT) devices attract significant attention for their low‐power consumption and high stability in applications. This review systematically outlines strategies for enhancing OT efficiency. We categorize approaches into boosting orbital currents/torques and improving the orbital‐to‐spin conversion coefficient.

Interconversion of Optical to Terahertz Pulses in Nonlinear Beta Barium Borate Crystal

Advanced Physics Research, EarlyView.
ABSTRACT Low‐temperature β‐phase barium borate (β‐BBO) is an important nonlinear crystal, widely utilized for optical second‐harmonic (SH) generation. Recent re‐measurements of refractive indices in the terahertz (THz) range reveal that β‐BBO is a positive uniaxial crystal.
