The first results are in from a new search for the axion, a hypothetical particle that may constitute dark matter. Researchers in the Haloscope At Yale Sensitive to Axion Cold Dark Matter (HAYSTAC) recently looked for evidence of the axion, but so far they have found none in the small 100 MHz frequency range between 5.7 and 5.8 GHz.

The experiment relied on the Lehnert group’s microwave...

Research associate Shimon Kolkowitz and his colleagues in the Ye group and Rey theory group have developed a powerful new way to experimentally simulate the complex behavior of electrons in solids. In these experiments, the team uses its strontium lattice optical clock not to track time, but to take advantage of the ultracold atoms in the clock mimicking the quantum behavior of electrons in a...

The winner of the 2005 Nobel Prize in Physics reflects on a career spent with a fascination for lasers and science. John L. Hall is a fellow and senior research associate at JILA, a joint institute of the University of Colorado at Boulder and the National Institute of Standards and Technology. He was awarded the 2005 Nobel Prize in Physics.

Hall is known as a pre-eminent laser...

Ultrasensitive Motion Detection

The Konrad Lehnert group is working on an ultrasensitive device that can precisely measure the vibrations of a tiny thin aluminum drum only 100-nm thick. The superconducting drum has a diameter of 15 µm. It forms the upper plate of a 50-nm capacitor, which is connected to a spiral inductor. Together they create a resonant circuit that can receive or transmit...
