Advanced experimental setup expands the hunt for hidden dark matter particles

Scientific evidence for dark matter comes from observing how it influences the motion of stars and galaxies. Scientists believe that dark matter may consist of particles. To search for these particles and their billiard ball-like ...

Research reveals a surprising topological reversal in quantum systems

In principle, one shouldn't compare apples to oranges. However, in topology, which is a branch of mathematics, one must do just that. Apples and oranges, it turns out, are said to be topologically the same since they both ...

Âé¶¹ÒùÔºicists capture first sounds of heat 'sloshing' in a superfluid, revealing how heat can move like a wave

In most materials, heat prefers to scatter. If left alone, a hotspot will gradually fade as it warms its surroundings. But in rare states of matter, heat can behave as a wave, moving back and forth somewhat like a sound wave ...
