Since this whirling BEC superfluid is operating at a quantum scale, where tiny distances and low temperatures reign, the physical characteristics of its rotation are not those seen in the classical world.
If at the boundary the superfluids continued to rotate faster on the inside, then the two semicircles would start to twist, elongating the line that separates them, and thus requiring more energy to stay separated.
«In a superfluid... things which are very far away [from the center] move really slowly, whereas things [that] are close to the center move very fast,» explains OIST Professor Thomas Busch, one of the researchers involved in the study.
Esslinger and his colleagues wondered if they could observe the transition from non-superfluid to superfluid, and use this as a model for studying the onset of superconductivity.
Cold clouds of atoms with unequal populations of atomic spins can maintain a surprisingly robust superfluid state, which requires paired spins.
When closed, the ultracold lithium gas built up and lost its superfluid properties — but when the channel was opened again, the lithium rapidly recovered superfluid, resistance - free flow.
Rather like electrons flowing without electrical resistance, at temperatures close to absolute zero, some atoms turn superfluid, flowing with no friction or physical resistance.
Robert Richardson worked on the superfluid properties of helium — now he worries that we are squandering our supplies of the gas
As a superfluid, atoms could flow down this channel, from the source to the drain.
This study relates to the long - standing debate about the nature of the superfluid state in Fermi systems.
In one model, a low - energy impact leaves the proto - Earth and Moon shrouded in a silicate atmosphere; in the other, a much more violent impact vaporizes the impactor and most of the proto - Earth, expanding to form an enormous superfluid disk out of which the Moon eventually crystallizes.
A NEARBY neutron star is chilling out, providing the first evidence that the cores of these collapsed stars can produce a neutron superfluid — an exotic state that can not be created on Earth.
On Earth Superfluids with properties such as climbing up the walls of their containers can be made from chilled atoms.
Calculations suggest that under the intense pressure in the cores of these stars, neutrons may pair up to form a frictionless superfluid.
They have used advanced mathematical methods to study unusual phases, or states, of matter, such as superconductors, superfluids or thin magnetic films.
If gravitational waves — ripples in space time — have a handedness, primordial particles could interact with them to form a dark matter superfluid that spreads through the cosmos
Now for the first time, researchers have made and photographed a superfluid drop that resolutely sits still — even when its perch is tilted.
But theorists predicted that one surface might have a shot at capturing a drop of superfluid: a sheet of cesium.
In the future, the team plans to build devices with hundreds of sites with which they hope to observe exotic phases of light such as superfluids and insulators.
A drop of superfluid helium (left, with its mirror image underneath) won't slide down a cesium surface.
With that magic ingredient, you can begin to make a superfluid sonic black hole.
The large orbit of the loosely bound outer electron of cesium atoms would repel the negative charge of the helium atom — overcoming the van der Waals forces that normally help spread superfluid helium over a surface.
Milton Cole of Pennsylvania State University in University Park thinks that tiny variations in the crystalline structure of the cesium could somehow provide a foothold for the superfluid.
Superfluids are immune to many of the forces that constrain ordinary liquids.
Put a drop of superfluid on most surfaces, and it spreads out into a thin layer, rather than beading like water on glass.
In the 1970s, Brinkman worked on superfluid helium with Anderson and Douglas Osheroff, both Nobelists but for different discoveries, before deciding to go into management.
A thermodynamic model explains that supersolid 4He — a solid that flows as a superfluid — is a crystal in which the number of lattice sites mismatches the number of atoms.
It becomes a new state of matter — a «superfluid
There is little chance of creating a soup of superfluid neutrons on Earth.
The dense core of a nearby collapsed star is undergoing a rapid chill, providing the first direct evidence that such stars can produce a superfluid of neutrons — a state of matter that can not be created in laboratories on Earth.
«New properties of rotating superfluids discovered in helium nanodroplets.»
As such, in a superfluid droplet, the rotation is evenly distributed in vortices, which allows the droplet to withstand stunningly large rotation speeds without forming lobes or disintegrating.
It has long been assumed that neutrons in the cores of neutron stars become superfluid, but without any direct evidence that they do so.
«Now we are able to study this form of matter in a new way that allows us to see how quantum mechanics manifests itself in the motion of an isolated superfluid,» Gessner said.
Superfluids made in laboratories are usually composed of chilled helium atoms.
If conditions are right, these neutrons ought to be able to pair up to form a superfluid — a substance with quantum properties that mean it flows with zero friction.
In addition, the group also noticed anomalously large numbers of vortices in the droplets, indicating they even behave differently than other superfluids.
Some speculate that studying superfluids could help understand the origins of the universe; in the moments following the Big Bang, the universe was uniform in density and similar to a superfluid.
The roots of the supersolid controversy go back to 1969, when Russian physicists predicted a state of solid matter in which gaps, or vacancies, in a crystal structure could move together as a single quantum wave — a collective motion reminiscent of the frictionless flow of a superfluid.
If the liquid has somewhere to fall after it climbs out of the dish, it will drip from the bottom of the container until it siphons out all the superfluid pooled above it.
