Rational Design of Donor‐Acceptor Oligomers for Enhanced Charge Separation

Advanced Physics Research, EarlyView.
How can molecular symmetry be broken to maximize photoinduced charge separation? Through first‐principles analysis of 22 DTP‐based donor‐acceptor ternary oligomers, this work establishes that combining architectural asymmetry with site‐selective acceptor fluorination creates an ideal electrostatic landscape for frontier orbital segregation.

Metasurfaces and Metadevices for Topological Electromagnetic Waves

Advanced Physics Research, EarlyView.
Optical topologies refer to diverse topological localized structures made by diverse parameters of light fields, such as vortices, skyrmions, and hopfions. This article navigates a direction of metasurface‐based integrated devices for generation, manipulation and detection of novel topologies of light, which would be a rapidly growing interdisciplinary

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.

Manipulating Ferroelectricity Without Electrical Bias: A Perspective

Advanced Physics Research, EarlyView.
Alternatives to electrical bias to control ferroelectric polarization are highly desired for the development of ferroelectric‐based applications. The polarizing role of chemically engineered surfaces, the impact of chemical substitution and mechanical pressure, and light‐induced effects on the final polarization state are highlighted in this short ...

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.
