It is possible to make a material absorb more radiation than it has to re-emit, violating the laws of physics in a way that ...

There are fundamentally two ways to generate electricity. The first is based on electromagnetic induction, which remains the backbone of global electricity production today. The second method uses ...

As few as five electrons in a semiconductor can exhibit collective behaviour, forming a “Coulomb liquid”, according to ...

Cold atoms are atoms that have been cooled to very low temperatures, below 1 mK, reducing their motion to a very low energy regime where quantum effects emerge. This makes them sensitive to some of ...

Using a clever laser technique, scientists have squished pairs of atoms closer together than ever before, revealing some truly mind-boggling quantum effects. Skip to main content Open menu Close menu ...

The 1st year of Dark Energy Spectroscopic Instrument (DESI) data seems to show that dark energy is weakening over time, possibly the biggest cosmological discovery for 25 years.

Ultra-cold atomic currents. This approach of shining twisted light through ultra-cold atoms opens a new and simple way of controlling and sculpting matter into unconventional and complex shapes.

One well-understood way to get atoms to cool off is to slow them down—by shooting them with a laser.This makes more sense than you’d think. Motion, kinetic energy, is also heat.
