I first learned of this area of research as a graduate student in physical chemistry. My doctoral adviser’s group had a project dedicated to studying chemical reactions with attosecond pulses. Before ...

The Nobel Physics Prize was awarded on Tuesday to three scientists for their work on attoseconds, which are almost unimaginably short periods of time. Their work using lasers gives scientists a tool ...

The 2023 Nobel Prize in physics has been awarded to three scientists who created pulses of light so short they can be used to watch the inner workings of atoms. Pierre Agostini, Ferenc Krausz, and ...

Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics. These engineered materials offer precise control over lights behavior, but ...

A spectrograph splits light ... Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of ...

By miniaturizing THz spectroscopy to a chip-scale platform, James McIver’s lab has uncovered a promising new method for controlling quantum materials. Under certain conditions, two-dimensional (2D) ...
