In the context of quantum physics, they help to explain phenomena such as superconductivity or quantum phase transitions at absolute zero. At a temperature of 0 Kelvin, instead of thermal fluctuations ...

Empty space is never actually truly empty. Even a quantum field in its lowest-energy state, the vacuum, has unavoidable fluctuations that arise from the Heisenberg uncertainty principle: Certain pairs ...

A little while ago,"What would happen to the world if vibrations stopped? Investigating absolute zero and zero-point motion"I ...

Physicists have tested the hypothesis that gravitational fluctuations in space-time can destroy quantum superposition and ...

So-called “exotic phases of matter” are currently a major focus of scientific research. There are two reasons for this. From the perspective of basic science, they represent a largely unexplored ...

In a new Physical Review Letters study, researchers propose an experimental approach that could finally determine whether gravity is fundamentally classical or quantum in nature. The nature of gravity ...

A deep-underground experiment in Italy has challenged a decades-old theory that gravity may destroy quantum superpositions. After 62 days of measurements at Gran Sasso, researchers found no trace of ...

Add Yahoo as a preferred source to see more of our stories on Google. Vortices in a Bose-Einstein condensate, a state of matter in which atoms collectively behave as a single quantum system. (NIST) ...

Jiang’s team and Wilczek also developed a theoretical model to explain how the effect could arise. Using a Ginzburg–Landau ...

Empty space in general is filled with silence. However, at the quantum level, emptiness is filled with unwanted noise. Now, a team of international researchers has found a way to use this noisy ...

In a supercooled lab setting, a tiny crystal has quietly flipped a half-century-old assumption on its head. Scientists at Rice University have reported the first direct observation of a long-predicted ...
