Electron chirp: Cyclotron radiation from single electrons measured directly for first time
A year before Albert Einstein came up with the special theory of relativity, or E=mc2, physicists predicted the existence of something else: cyclotron radiation. Scientists predicted this radiation to be given off by electrons ...
Simplified model predicts patterns that form from honey-like fluids
Drizzling honey on toast can produce mesmerizing, meandering patterns, as the syrupy fluid ripples and coils in a sticky, golden thread. Dribbling paint on canvas can produce similarly serpentine loops and waves.
New tabletop detector 'sees' single electrons
MIT physicists have developed a new tabletop particle detector that is able to identify single electrons in a radioactive gas.
Researchers find a way to convert waste heat to electricity at nano-scale
Long-sought magnetic mechanism observed in exotic hybrid materials
Scientists have measured the subatomic intricacies of an exotic phenomenon first predicted more than 60 years ago. This so-called van Vleck magnetism is the key to harnessing the quantum quirks of topological insulators—hybrid ...
Flip-flopping black holes spin to the end of the dance
When black holes tango, one massive partner spins head over heels (or in this case heels over head) until the merger is complete, said researchers at Rochester Institute of Technology in a paper published in Physical Review ...
New understanding of electromagnetism could enable 'antennas on a chip'
A team of researchers from the University of Cambridge have unravelled one of the mysteries of electromagnetism, which could enable the design of antennas small enough to be integrated into an electronic chip. These ultra-small ...
Researchers use 'soft' nanoparticles to model behavior at interfaces
Where water and oil meet, a two-dimensional world exists. This interface presents a potentially useful set of properties for chemists and engineers, but getting anything more complex than a soap molecule to stay there and ...
Black holes don't erase information, scientists say
The "information loss paradox" in black holes—a problem that has plagued physics for nearly 40 years—may not exist.
