In this study, researchers developed an ultrafast infrared near-field optical microscopy technique that combines nanoscale spatial resolution and an approximately 150-femtosecond temporal resolution with a spectral resolution of about 10 cm⁻¹.
A new measurement method reveals that light can twist nanoscale objects in unexpected ways. Light is not just something we see. It can also exert physical forces that push and twist matter. In the 1870s, James Clerk Maxwell proposed that light carries momentum and can apply pressure to objects. Nearly 100 years later, in the [...]
