«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.
Cold clouds of atoms with unequal populations of atomic spins can maintain a surprisingly robust superfluid state, which requires paired spins.
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.
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 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.
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.
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.
By using the superfluid helium analogy, we have predicted that there should be other Higgs bosons, which are much heavier (about 1 TeV) than previously observed,» says Professor (emeritus) Grigory E. Volovik.
All bulk liquid superfluids are caused by Bose - Einstein condensation, which is the quantum process whereby a large number of particles all enter the same quantum state.
In a class of superfluids, we produced very convincing evidence for the direction of this kind of flow, which would otherwise be very hard to obtain.»
To the researchers» surprise, their calculations showed that turbulent flows of a class of superfluids on a flat surface behave not like those of ordinary fluids in 2 - D, but more like 3 - D fluids, which morph from relatively uniform, large structures to smaller and smaller structures.
These days even undergraduates create so - called Bose - Einstein condensates (BECs) in the lab, many of which can be classified as superfluids.
