MIT researchers have developed a new atomic clock that can keep time more precisely thanks to the use of entangled atoms, reports Leila Stein for Popular Mechanics. “If all atomic clocks worked the way this one does then their timing, over the entire age of the universe, would be less than 100 milliseconds off,” Stein writes.
Physics World selected a study by researchers from MIT’s LIGO Lab that shows quantum fluctuations can jiggle objects as large as the mirrors of the LIGO observatory as one of the top 10 breakthroughs of the year. “The research could lead to the improved detection of gravitational waves by LIGO, Virgo and future observatories,” notes Hamish Johnston for Physics World.
Symmetry Magazine reporter Sarah Charley writes that a new study co-authored by MIT postdoc Xiaojun Yao examines how quantum computing could advance our understanding of quantum processes. Yao explored how “the properties of a heavy particle could be impacted after it traversed through a quark-gluon plasma,” and after several months of testing was able to “demonstrate that these kinds of calculations are already feasible on today’s quantum computers.”
Writing for Popular Mechanics, Leila Stein highlights how MIT researchers have created a perfect fluid and captured its sound. “To record the sound, the team of physicists sent a glissando of sound waves through a controlled gas of elementary particles called fermions,” Stein writes.
Prof. Martin Zwierlein speaks with Edgar Herwick III of GBH Radio about his work capturing the sound of a “perfect” fluid. "It was a beautiful sound," says Zwierlein. "It was a quantum sound. In a way it was the most long-lasting sound that you can imagine given the laws of quantum mechanics.”
New Scientist reporter Abigail Beall spotlights how MIT researchers have listened to sound waves traveling through a "perfect" fluid, which could shed light on the resonant frequencies within a neutron star. “The quality of the resonances tells me about the fluid’s viscosity, or sound diffusivity,” says Prof. Martin Zwierlein. “If a fluid has low viscosity, it can build up a very strong sound wave and be very loud, if hit at just the right frequency. If it’s a very viscous fluid, then it doesn’t have any good resonances.”
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.”
MIT seniors Danielle Grey-Stewart and Ghadah Alshalan have been selected for the 2021 Rhodes Scholarship program, reports Gal Tziperman Lotan for The Boston Globe.
Research scientist Clara Sousa-Silva speaks with Wired reporter Abigail Beall about phosphine, a molecule that she has spent the past decade investigating. “Phosphine is a horrific molecule, it’s foul in every way,” she says. “It’s almost immoral, if a molecule can be.”
Writing for Science, Charlie Greenwood spotlights how MIT researchers are building upon their pioneering work twisting sheets of graphene together to create superconductors by using twisted graphene to develop working devices. “Many researchers are excited by the promise of exploring electronic devices without worrying about the constraints of chemistry,” writes Greenwood.
A team of astronomers, including MIT researchers, have identified fast radio burst emanating from a magnetar in our galaxy, reports Doyle Rice for USA Today. “The radio pulses are the closest ones detected to date, and their proximity has allowed the team to pinpoint their source.”
Prof. Kiyoshi Masui speaks with Verge reporter Loren Grush about how astronomers have detected fast radio bursts coming from a magnetar within our own galaxy. “This is the missing link,” Masui says. “Now we’ve seen a fast radio burst coming from a magnetar, so it proves that at least some fraction of fast radio bursts we see in the universe come from magnetars.”
Graduate student David Berardo has demonstrated how science enthusiasts can measure the speed of light at home using a bar of chocolate and the microwave, reports Caroline Delbert for Popular Mechanics. After microwaving the chocolate for about 20 seconds, “what you’ll see is a specific pattern of melting that shows the wavelength of the microwaves that power your oven.”
A study co-authored by senior lecturer Richard Price explores the physics behind a spiraling football pass, reports Kenneth Chang for The New York Times. “I went on to apply some pretty simple mathematics and do what physicists do," says Price. “Which is to try and throw away all of the irrelevant details and get the heart of something.”
Wall Street Journal Jason Gay spotlights a new study co-authored by Senior Lecturer Richard Price that explores the physics behind the spiraling flight of a thrown football. “Physicists get interested in stuff that bores other people,” Price explains. “When you combine torque with the gyroscopic effect of the angular momentum, the two work together, so that in an average sense, the spin axis is very close to tangent to the path.”
