Origin of superfluid

Example Sentences

The B-L flux tube provides a structure for the PQ superfluid vortex's Chern-Simons coupling to attach to.

From Science Daily

The breaking of the B-L symmetry produced strings that behave like magnetic flux tubes, while the PQ symmetry created superfluid vortices that carry no magnetic flux.

From Science Daily

In turn, this coupling allows the PQ superfluid vortex to pump electric charge into the B-L flux tube and oppose the tension that would normally cause the loop to shrink and snap.

From Science Daily

Dr Svancara continues: "Superfluid helium contains tiny objects called quantum vortices, which tend to spread apart from each other. In our set-up, we've managed to confine tens of thousands of these quanta in a compact object resembling a small tornado, achieving a vortex flow with record-breaking strength in the realm of quantum fluids."

From Science Daily

They have created a giant swirling vortex within superfluid helium that is chilled to the lowest possible temperatures.
