In everyday life, all matter exists as either a gas, liquid, or solid. In quantum mechanics, however, it is possible for two distinct states to exist simultaneously. An ultracold quantum system, for ...

Superfluid helium exhibits a range of remarkable physical phenomena that challenge conventional fluid dynamics and heat transfer theories. At temperatures near absolute zero, helium transitions into a ...

Bose-Einstein condensates (BECs) are fascinating states of matter that emerge when atoms or molecules are cooled to extremely low temperatures just slightly above absolute zero (0 K). In 2023, ...

Supersolids are a form of quantum matter that exhibits properties of a superfluid (zero viscosity), but with a spatially ordered structure. Although usually created from ultracold atoms, scientists ...

Superfluid helium represents a fascinating state of matter, manifesting unique quantum mechanical behaviours at ultralow temperatures, including frictionless flow and the absence of viscosity. In ...

Quantum vortices—tiny whirlpools in the quantum fluid— cause the precession and revolution of the superfluid crystal structure to synchronize their motion. A supersolid is a paradoxical state of ...

Supersolids, a state of matter that combines the rigidity of a solid with the frictionless flow of a superfluid, exhibit surprising synchronization when rotated. Innsbruck researchers found that ...

In popular science, dark matter is a hotly discussed topic. With various theories regarding its existence and interaction with regular matter, many scientists agree that these are some questions that ...

The nature of dark matter remains one of the greatest mysteries in cosmology. Within the standard framework of non-collisional cold dark matter (CDM), various models are considered: WIMPs (Weakly ...
