Researchers at the Niels Bohr Institute have managed to successfully combine two worlds: quantum physics and nano physics.
The joining of two very distinct universes has already led to the discovery of a new method for laser cooling semiconductor membranes.
As you probably already know, semiconductors are vital components in solar cells, LEDs and many other electronic devices. 
As such, the efficient cooling of components is critical for the design of future quantum computers and ultrasensitive sensors.
So how does the new cooling method work?
Quite paradoxically – by actually heating the material! Indeed, using lasers, researchers cooled membrane fluctuations to minus 269 degrees C.
