Over the past decades, researchers have made significant progress in cooling objects closer to absolute zero, the temperature at which all molecular motion reaches its minimum. This has allowed them ...

It may sound less likely than hell freezing over, but physicists have created an atomic gas with a sub-absolute-zero temperature for the first time 1. Their technique opens the door to generating ...

Tapio Simula receives funding from Australian Research Council (ARC). He is affiliated with American Physical Society (APS). He works for Monash University. The concept of temperature is intimately ...

Absolute zero is often thought to be the coldest temperature possible. But now researchers show they can achieve even lower temperatures for a strange realm of "negative temperatures." Oddly, another ...

Nothing is colder than absolute zero, so it seems nonsensical to talk about negative temperature – but now there is a substance that must have just that. The revelation could shake up our ideas about ...

Coaxing a gas to a negative temperature on the kelvin scale has produced, paradoxically, the hottest temperature ever measured. The study, published in the Jan. 4 Science, will help physicists learn ...

Over the past 60 years, several theories and experiments have claimed the existence of negative absolute temperatures in certain quantum systems. This fueled speculations about hyper-efficient heat ...
