Curved spacetime in a quantum simulator
The theory of relativity works well when you want to explain cosmic-scale phenomena - such as the gravitational waves created when black holes collide. Quantum theory works well when describing particle-scale phenomena - such as the behavior of individual electrons in an atom.
The Physics of Gummy Candy
In Physics of Fluids, researchers conduct a series of experiments that explore how changing key parts of the gummy-making process affects the final product, as well as how the candies behave in different storage temperatures. The group adjusted a variety of inputs while making the gummies, from the glucose syrup-to-sucrose ratio to starch and gelatin concentrations, to understand how these changes affected features like candy texture, moisture content, and pH. They used these results to identify the most shelf-stable combination for gummy candies.
Journal of Mathematical Physics Announces 2022 Young Researcher Award
The Journal of Mathematical Physics has selected Tom Hutchcroft for the 2022 JMP Young Researcher Award. Hutchcroft's winning publication, "Sharp hierarchical upper bounds on the critical two-point function for long-range percolation on ℤd," demonstrated that hierarchical percolation models provide good quality estimates when compared to Euclidean models. A panel of expert judges selected Hutchcroft for the $3,000 prize, which recognizes JMP authors within eight years of receiving their doctorate. His paper will be highlighted on the journal's website.
Seeing electron orbital signatures
No one will ever be able to see a purely mathematical construct such as a perfect sphere. But now, scientists using supercomputer simulations and atomic resolution microscopes have imaged the signatures of electron orbitals, which are defined by mathematical equations of quantum mechanics and predict where an atom's electron is most likely to be.

Tidal shocks can light up the remains of a star being pulled apart by a black hole
A new study sheds light on the bright outbursts of radiation that are created when a star is destroyed by a supermassive black hole. The outbursts do not necessarily form in the close vicinity of the black hole, but are created by tidal shocks that occur when gas from the destroyed star hits itself while circling the black hole.
Ultralow temperature terahertz microscope capabilities enable better quantum technology
A team of scientists from the Department of Energy's Ames National Laboratory have developed a way to collect terahertz imaging data on materials under extreme magnetic and cryogenic conditions.

Solar-Powered Balloons Detect Mysterious Sounds in the Stratosphere #ASA184
To reach the stratosphere, Daniel Bowman of Sandia National Laboratories and his collaborators build relatively simple, solar-powered balloons that span 6 to 7 meters across. After releasing the balloons, they track their routes using GPS and use them to collect data and detect low-frequency sound with microbarometers. Rarely disturbed by planes or turbulence, the microphones on the balloons pick up a variety of sounds unheard anywhere else. Bowman will present his findings using these hot air balloons to eavesdrop on stratospheric sounds at the upcoming 184th ASA Meeting.

Fire Hydrant Hydrophones Find Water Leaks #ASA184
Acoustic monitoring is the go-to solution for locating a leak in a large urban pipe network, as the sounds from leaks are unique and travel far in water, but even this method struggles in complex systems. To tackle the problem, Pranav Agrawal and Sriram Narasimhan from UCLA developed algorithms that operate on acoustic signals collected via hydrophones mounted on fire hydrants. In doing so, the team can avoid costly excavation and reposition the devices as needed. Combined with novel probabilistic and machine-learning techniques to analyze the signals and pinpoint leaks, this technology could support water conservation efforts.
