A new hands-off probe uses light to explore the subtleties of electron behavior in a topological insulator
Just as pressing a guitar string produces a higher pitch, sending laser light through a material can shift it to higher energies and higher frequencies. Now scientists have discovered how to use this phenomenon to explore quantum materials in a new and much more detailed way.

An advance in molecular moviemaking reveals the subtle, complex ways a simple molecule can shimmy and fly apart
Hitting molecules with two photons of light at once set off unexpected processes that were captured in detail with SLAC’s X-ray laser. Scientists say this new approach should work for bigger and more complicated molecules, too, allowing new insights into molecular behavior.
