New experimental results on the behavior of ultracold, two-dimensional gases reported by physicists may help clarify the mysterious phenomenon called "superfluidity" -- frictionless flow. If ...

Supersolids are a new form of quantum matter that has only recently been demonstrated. The state of matter can be produced artificially in ultracold, dipolar quantum gases. A team has now demonstrated ...

In 2004 researchers reported the first clear evidence for superfluidity in solid helium-4. However, Matthew Chalmers describes recent experimental and theoretical work that has brought the very ...

Ultracold lab: To demonstrate superfluidity in molecular hydrogen, researchers at the University of British Columbia, RIKEN and Kanazawa University confined the molecules within a nanodroplet of ...

Duke University researchers may have reached a milestone in physics by cooling and confining a gas of lithium-6 atoms into a kind of oscillating “jelly” exhibiting group behavior uncharacteristic of ...

Superfluidity as a research area investigates quantum condensed phases of matter that exhibit frictionless flow, quantized circulation, and macroscopic quantum coherence, primarily in systems such as ...

Flow without friction is a strange phenomenon usually seen in quantum fluids that are cooled to temperatures near absolute zero, but features of superfluidity have now been seen with polaritons at ...

(Nanowerk News) Matter that behaves like both a solid and a superfluid at the same time seems impossible. Yet, more than 50 years ago, physicists predicted that quantum mechanics allows such a state, ...
