The day the universe froze: New dark energy model includes cosmological phase transition
Imagine a time when the entire universe froze. According to a new model for dark energy, that is essentially what happened about 11.5 billion years ago, when the universe was a quarter of the size it is today.

Beam balance designs could elucidate the origins of dark energy
One of the greatest problems in modern physics is to reconcile the enormous difference between the energy carried by random fluctuations in the vacuum of space, and the dark energy driving the universe's expansion.

Research reveals quantum entanglement among quarks
Collisions of high energy particles produce "jets" of quarks, anti-quarks, or gluons. Due to the phenomenon called confinement, scientists cannot directly detect quarks. Instead, the quarks from these collisions fragment ...

Single nanoscale hybrid system for studying the vacuum fluctuation field
When you think of empty space, you almost certainly imagine a vacuum in which nothing interesting can ever happen. However, if we zoom in to tiny length scales where quantum effects start to become important, it turns out ...

Physicists make most precise measurement yet of magnetic moment of an electron
A combined team of physicists from Harvard University and Northwestern University has found the most precise value yet for the magnetic moment of an electron. In their paper published in the journal Physical Review Letters, ...
Research group advances quantum sensing with a new model in optical fibers
Research into quantum engineering may provide a number of significant advancements in sensor technology, but optical loss and signal noise have—until recently—held these applications back. In "Realistic model of entanglement-enhanced ...
