Atoms

The Center for UltraCold Atoms, located at MIT, is one of four university physics programs that will share $76 million in funding from the National Science Foundation as part of the organization’s Physics Frontiers Centers program, which aims to “foster major breakthroughs at the intellectual frontiers of physics,” writes Michael T. Nietzel for Forbes. “[T]he Center for UltraCold Atoms is a joint effort with Harvard University that will explore how to achieve greater control and programmability of complex quantum systems,” he explains.

Scientists from MIT have observed a quantum effect that blocks ultracold atoms from scattering light, reports Emily Conover for Science News. To observe the effect, the researchers “beamed light through a cloud of lithium atoms, measuring the amount of light it scattered,” writes Conover. “Then, the team decreased the temperature to make the atoms fill up the lowest energy states, suppressing the scattering of light.”

Prof. Martin Zwierlein speaks with Madeline Sofia and Emily Kwong of NPR’s Short Wave about his work with ultracold quantum gases and observing superfluid states of matter. “Luckily we have techniques to actually take rather beautiful pictures of this quantum soup of these whirlpools of individual atoms,” says Zwierlein, “to try and make it out of this invisible realm and make it very real, touchable.”

Scientific American reporter Daniel Garisto spotlights how a team of MIT researchers has uncovered hints of anomalous activity in heavy isotopes. “We’re not claiming to have discovered anything like a new particle,” says Prof. Vladan Vuletić. “Most likely, we are measuring new nuclear physics, but there is the possibility of something else going on.”
