Yale scientists have discovered that laser light can be used to cool traveling sound waves in a silicon chip. Their findings appear in the Nov. 27 online edition of the journal Physical Review X.

In the last several decades, the ability to cool clouds of atoms using laser light has revolutionized atomic physics, leading to the discovery of new states of matter and better atomic clocks. Laser cooling relies on the fact that photons, or light particles, carry momentum and can exert a force on other objects.

These techniques have recently been adapted to slow down, or cool, mechanical oscillators comprised of billions of atoms. This type of cooling has become an enabling technique for exploring the quantum properties of mechanical objects and reducing forms of noise that would otherwise corrupt precision measurement.

Four Yale faculty members have been named fellows of the American Association for the Advancement of Science (AAAS), an honor bestowed upon AAAS members by their peers.

The 416 members have been awarded this honor by the AAAS in recognition of their scientifically or socially distinguished efforts to advance science or its applications.

The awardees are: Charles H. Ahn, the William K. Lanman Jr. Professor of Applied Physics and chair of the Department of Applied Physics; Richard G. Bribiescas, professor of anthropology and ecology and evolutionary biology and deputy provost for faculty development and diversity; Christopher G. Burd, professor and deputy chair of cell biology; and Dragomir Radev, the A. Bartlett Giamatti Professor of Computer Science.

Most scientists will never have the opportunity to travel to the South Pole for their research, but then again, most scientists aren’t Faustin Carter (PhD ’15). Carter works as a postdoctoral researcher at Argonne National Laboratory in the High Energy Physics division. He is part of a group that specializes in building detectors for esoteric applications. The group’s primary focus over the last several years has been building and testing detectors for a massive upgrade to a telescope located at the geographic South Pole in Antarctica.

Dan Prober received the IEEE Council on Superconductivity award for 2018.
The award given in recognition of  his continuing and significant contributions in the field of superconductive electronics, in particular: 
  • for pioneering work on SIS quasiparticle mixers, including the first demonstration of detector sensitivity approaching the quantum limit;
  • for inventing the diffusion-cooled hot electron bolometer, a high sensitivity and large-bandwidth superconducting heterodyne mixer;
  • for advancements in nanofabrication that have been used to develop ultra-sensitive devices based on superconducting nanostructures; and
  • for fundamental studies of noise in mesoscopic superconducting systems, which have improved our understanding of the sensitivity limits of superconducting devices.
