Quantum vortex formation in the lab

Quantized vortices can be generated in classical experiments of liquid helium and ultracold dilute gases to conduct fundamental and comparative studies of different superfluids. In a new report published in Science Advances, ...

New quantum criticality discovered in superconductivity

Using solid state nuclear magnetic resonance (ssNMR) techniques, scientists at the U.S. Department of Energy's Ames Laboratory discovered a new quantum criticality in a superconducting material, leading to a greater understanding ...

Researchers explain emergence of bacterial vortex

When a bunch of B. subtilis bacteria are confined within a droplet of water, a very strange thing happens. The chaotic motion of all those individual swimmers spontaneously organizes into a swirling vortex, with bacteria ...

Harnessing magnetic vortices for making nanoscale antennas

(Phys.org) —Scientists at the U.S. Department of Energy's Brookhaven National Laboratory are seeking ways to synchronize the magnetic spins in nanoscale devices to build tiny yet more powerful signal-generating or receiving ...

Researchers see Kelvin wave on quantum 'tornado' for first time

A spinning tornado of very cold liquid helium obeys the laws of quantum mechanics. Sometimes, two quantum tornadoes flex into curved lines, cross over and form an X, swap ends, and then retract—a process called reconnection. ...

Solving a physics mystery: Those 'solitons' are really vortex rings

(Phys.org) —The same physics that gives tornadoes their ferocious stability lies at the heart of new University of Washington research, and could lead to a better understanding of nuclear dynamics in studying fission, superconductors ...
