Bose-Einstein condensate
"Quantum tornadoes" mark crossover from classical to quantum physics
The universe is governed by two sets of seemingly incompatible laws of physics – classical and quantum physics. MIT physicists have now observed the moment atoms switch from one to the other, as they form intriguing "quantum tornadoes."
Quantum gas free fall experiment creates coldest temperature ever recorded
German physicists have recorded the coldest temperature ever – 38 trillionths of a degree above absolute zero. The experiment involved dropping quantum gas and switching a magnetic field on and off to bring its atoms to an almost complete standstill.
Strange supersolid state of matter created in new dimension
There are many exotic states of matter besides the basics of solid, liquid, gas and plasma. One of these, known as a supersolid, was confirmed a few years ago, and now University of Innsbruck scientists have created it in a new two-dimensional form.
Molecules wrangled into single quantum state in breakthrough experiment
Quantum technology is bursting with potential, but controlling atoms and molecules keeps proving tricky. In a breakthrough new study, physicists have successfully wrangled thousands of molecules into a single unified quantum state for the first time.
"Fifth state of matter" used to make new type of superconductor
Superconductors – materials in which electricity flows without any resistance whatsoever – could be extremely useful. For the first time ever, engineers have created a superconductor out of a state of matter called a Bose-Einstein condensate (BEC).
Schrödinger's Art: Spooky physics paints microscopic artworks on "quantum canvas"
Researchers have produced what may very well be the first pieces of art made using non-classical matter. The team has reproduced classic artworks like the Mona Lisa and Starry Night on a "quantum canvas" as small as a human hair, by projecting light onto Bose-Einstein condensates (BECs).
Quantum ball lightning forged in the lab for the first time
Ball lightning has been consistently reported for centuries, and yet we still know very little about it. Now, scientists have created quantum ball lightning by knotting together the magnetic spins of atoms, which could help unlock the secrets of the phenomenon, or make more stable fusion reactors.
"Giant atoms" swallow other atoms to form new state of matter
As tiny as they are, there's a relatively large amount of empty space inside an atom. Now, scientists from Austria and the US have filled in some of those gaps, creating a new state of matter in the form of "giant atoms" filled with other atoms.
Long-theorized new form of matter, excitonium, finally discovered
Physicists have discovered a new form of matter called excitonium. First theorized almost 50 years ago, the Illinois researchers have found a "smoking gun" that they claim is the first definitive proof that excitonium exists.
Scientists create negative-mass fluid that flows against the force
If you pushed a ball with negative mass, it would move towards you. It might be hard to picture, but according to Newtonian physics it should be possible. Now a team at Washington State University has demonstrated the phenomenon in practice, creating a fluid that has the properties of negative mass.
Theoretical "supersolid" state of matter created in two separate studies
An unusual state of matter, first theorized almost 50 years ago, has been created in experiments for the first time. Say hello to the supersolid, a state where atoms simultaneously exhibit a crystalline structure but still flow like a frictionless fluid.
Liquid light switch bridges the gap between light and electricity
Scientists have used a form of liquid light to create a semiconductor switch that is so small that it not only blurs the distinction between light and electricity, but could also enable the development of much faster and smaller electronic components well into the future.
