From Phys.org, Jan. 25, 2023: Researchers at Fermilab, Northwestern University and Stanford University recently demonstrated an entirely new method for searching for meV dark matter. The group is testing a hypothesis that when the rest energy of a dark photon matches the energy splitting of the two lowest cyclotron levels, the first state of the electron cyclotron will be excited.

Physics students often ask how it is that a massless photon can have momentum. In this video, Don Lincoln shows that the question arises from a misuse of equations and also shows that, when you think about it, it’s not surprising at all.
There’s no one best way to build a telescope.
The quantum eraser experiment is one of the weirdest phenomena that has ever been observed. It seems that quantum mechanics mixes past and future together. In this video, Fermilab’s Don Lincoln takes you through this quantum conundrum.
The ATLAS experiment at CERN sees possible evidence of quark-gluon plasma production during collisions between photons and heavy nuclei inside the Large Hadron Collider.
Quantum mechanics is one of the most confusing fields of contemporary physics. Fermilab’s Don Lincoln introduces the big ideas and prepares the viewer for a follow-on video that is even more mind-blowing.
Quanta of light called photons are the smallest possible packets of electromagnetic energy. Learn the history behind how scientists came to understand photons — and what these particles have shown us (and might show us) they can do.
From U Chicago News, April 13, 2021: Scientists at the U.S. Department of Energy’s Fermi National Accelerator Laboratory and the University of Chicago have demonstrated a new technique based on quantum technology that will advance the search for dark matter, which accounts for 85% of all matter in the universe.
Quantum bits acting as particle detectors offer a fast and highly reliable means of solving one of the great mysteries in physics: the nature of dark matter. This new method promises a more efficient way to detect dark matter candidates by improving the experimental signal-to-noise ratio.
From Berkeley Lab, Feb. 17, 2021: Fermilab is part of a team of national labs that designed, built and fully tested a prototype magnet for today’s and tomorrow’s light sources. These light sources let scientists see things once thought impossible. They can use these visions to create more durable materials, build more efficient batteries and computers, and learn more about the natural world.
