Twist in Light Enhances Chiral Discrimination

Researchers from IIT Bombay led by Prof. Gopal Dixit, Department of Physics; Tata Institute of Fundamental Research (TIFR) and IIT Hyderabad have developed a novel optical technique to distinguish between mirror-image molecules, known as enantiomers, using specially structured “twisted” laser light. Published in Science Advances, the study demonstrates that laser beams carrying orbital angular momentum interact differently with chiral molecules depending on their handedness.

Unlocking High-Frequency Surface Acoustic Waves in Silicon: A New Frontier for Phononic and Quantum Devices

Surface acoustic waves (SAWs) −tiny elastic vibrations that travel along the surface of a solid−are the unsung heroes of modern wireless technology, powering the radio-frequency filters in every smartphone. As wireless communication advances towards 5G, 6G, and millimeter-wave (mm-wave) technologies, there is growing demand for compact, low-loss, and ultra-high-speed signal-processing devices compatible with existing silicon electronics.
