The gravitational waves created by black holes or neutron stars in the depths of space have been found to reach Earth. Their effects, however, are so small that they can only be observed using kilometer-long measurement facilities. ...

Over the past few decades, some physicists worldwide have been trying to use the second layer of 4He films adsorbed on a graphite substrate to study the interplay between superfluid and supersolid phases of matter. Some teams ...
Physicists have been studying superfluid 3He under nanoscale confinement for several years now, as this unique liquid presents a rich variety of phases with complex order parameters that can be stabilized. While past studies ...
(Phys.org) —In order to study many complex phenomena, physicists seek to isolate them in potential wells or boxes with easily described forms and boundary conditions. These features in turn dictate various behaviors of ...
Picture a nanoscale dance floor full of independently moving particles. When things really start to heat up—or, in this case, cool down—particles partner off, but on opposite sides of the space, "dancing" in synch as ...

If a drop of creamer falls from a spoon into a swirling cup of coffee, the whirlpool drags the drop into rotation. But what would happen if the coffee had no friction—no way to pull the drop into a synchronized spin?

A hybrid matter—an antimatter helium atom containing an antiproton, the proton's antimatter equivalent in place of an electron, has an unexpected response to laser light when immersed in superfluid helium, reports the ASACUSA ...

Every fluid—from Earth's atmosphere to blood pumping through the human body—has viscosity, a quantifiable characteristic describing how the fluid will deform when it encounters some other matter. If the viscosity is higher, ...
