When many quantum particles interact, complex systems can be formed. And this complexity allows reaching a temperature of absolute zero—at least in principle. The absolute lowest temperature possible ...

It is no secret that semiconductor junctions change their behavior with temperature, and you can use this fact to make a temperature sensor. The problem is that you have to calibrate each device for ...

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." Subscribe to ...
