News: A cloud of ultracold atoms can store a beam of yellow
light for 1.5 seconds,
says
a new paper by researchers led by
Lene Hau of
Harvard University.The new study is "a beautiful
demonstration," says Irina Novikova, a physicist at the College
of William & Mary in Williamsburg, Virginia. Before this
result, she says, light storage was measured in milliseconds.
"Here, it's fractional seconds. It's a really dramatic time."
