Trapping vortices in thin superfluid films
Physicists at the University of Queensland have shed light upon how tiny whirlpools (vortices) get stuck to obstacles in superfluids.

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 ...
Researchers at Rochester Institute of Technology are part of a new study that could help unlock the potential of superfluids—essentially frictionless special substances capable of unstopped motion once initiated. A team ...

A team of researchers from the Institute for Quantum Optics and Quantum Information and the University of Innsbruck, has developed a technique for characterizing the phases a superfluid undergoes as it changes to a supersolid ...
A team of researchers working at the Institut für Laserphysik, Universität Hamburg, has found evidence of superfluidity in an extremely cold 2D gas of fermions. In their paper published in the journal Science, the group ...

Superfluidity in liquids and gases can manifest as a reduced moment of inertia (the rotational analog of mass) under slow rotations. Non-classical rotational effects can also be considered in the elusive supersolid phases ...
