Dark Fiber: Using Sensors Beneath Our Feet to Tell Us About Earthquakes, Water, and Other Geophysical Phenomena

December 5th, 2017

Scientists at Lawrence Berkeley National Laboratory have shown for the first time that dark fiber – the vast network of unused fiber-optic cables installed throughout the country and the world – can be used as sensors for detecting earthquakes, the presence of groundwater, changes in permafrost conditions, and a variety of other subsurface activity.

Watching a Quantum Material Lose Its Stripes

November 29th, 2017

In quantum materials, periodic stripe patterns can be formed by electrons coupled with lattice distortions. To capture the extremely fast dynamics of how such atomic-scale stripes melt and form, Berkeley Lab scientists used femtosecond-scale laser pulses at terahertz frequencies. Along the way, they found some unexpected behavior.

A Flight Path to Physics Success

November 22nd, 2017

In a previous career with the U.S. Air Force, Sandra Miarecki flew high above the Earth’s surface. She retired from the Air Force in 2007 to pursue a new calling in physics that would set her sights on particles traveling into the depths of the Earth.
