Donna Strickland: Life in the (ultra)fast lane

Matt Yeh is a first-year Ph.D. student in the Applied Physics program at Harvard University. He is interested in studying how light-matter interaction can be used for quantum information science. Jovana Andrejevic is a fifth-year Applied Physics Ph.D.…

Donna Strickland: Life in the (ultra)fast lane

by Matthew Yeh Donna Strickland during Nobel press conference, 2018 Ever wondered how laser eye surgery can be so precise, or how scientists can study processes that unravel over a billionth of a billionth of a second? Donna Strickland has got you…

Sticky Light: Physicists discover new Photon Interactions

Light is made of little particles called photons that usually don’t interact. Imagine how strange it would be if the light from your window ricocheted off the light from computer screen! Our brains couldn’t make sense of these images and we’d be…

A Freeway for Light: Topology Protects Lasers from Defects

If you want to admire the beauty behind the 2016 Nobel Prize in Physics – topological phases of matter, take a course in topology, followed by graduate-level solid state physics. But if you ask for a concrete application of this topic, you now have an…
