Laser squared: A two-domain photon-phonon laser

Lasers are a significant historical invention with ubiquitous impact in society. The concept also has interdisciplinary applications as phonon lasers and atom lasers. A laser in one physical domain can be pumped by energy ...

Physicists uses light to build complex structures

Ph.D. candidate Petr Steindl creates complex structures of light using single photons. As a teenager, he wanted to study Czech poetry but decided on quantum physics. "Looking back, I am glad I switched fields," he says. On ...

How splitting sound might lead to a new kind of quantum computer

When you turn on a lamp to brighten a room, you are experiencing light energy transmitted as photons, which are small, discrete quantum packets of energy. These photons must obey the sometimes strange laws of quantum mechanics, ...

Photonics experiment resolves quantum paradox

It seems quantum mechanics and thermodynamics cannot be true simultaneously. In a new publication, UT researchers use photons in an optical chip to demonstrate how both theories can be true at the same time. They recently ...
