These things were not predicted under any theory and surprised
scientists when they appeared unexpectedly in extremely low temperature
semiconductor experiments. They have properties unlike anything seen
“At first we scratched our heads,” said physicist Steven Cundiff of the University of Colorado and National Institute of Standards and
Technology in Boulder, one of the authors of a paper appearing today in Nature. “But then we came up with this idea that what we were seeing was this new thing we’re calling a quantum droplet.”
Now before you start asking questions like, “What?” and “Huh?” we probably need to break things down a little here.
There are materials, such as metals, that are good conductors of
electricity. Inside of a conductor like copper wire are countless copper
atoms arranged in a lattice. The electrons of the copper atoms become
unbound from their nuclei and are free to flow, allowing them to easily
carry a current. The opposite of this is an insulator, like rubber, in
which electrons stay put.
