Scientists at the Institute for Photonic Quantum Systems (PhoQS) and the Paderborn Center for Parallel Computing (PC2) at Paderborn University have developed a powerful open-source software tool that allows them to simulate light behavior in quantum systems.

The unique feature of this tool, named “Phoenix,” is that researchers can use it to very quickly investigate complex effects to a level of detail that was previously unknown, and all without needing knowledge of high-performance computing. The results have now been published in Computer Physics Communications.

Phoenix solves equations that describe how light interacts with material at the quantum level, which is essential for under...

For the first time ever, scientists have watched electrons perform a bizarre quantum feat: tunneling through atomic barriers by not just slipping through, but doubling back and slamming into the nucleus mid-tunnel. This surprising finding, led by POSTECH and Max Planck physicists, redefines our understanding of quantum tunneling—a process that powers everything from the sun to your smartphone.

Recently, Professor Dong Eon Kim from POSTECH’s Department of Physics and Max Planck Korea-POSTECH Initiative and his research team have succeeded in unraveling for the first time the mystery of the ‘electron tunneling’ process, a core concept in quantum mechanics, and confirm...

Neutrinos are cosmic tricksters, paradoxically hardly there but lethal to stars significantly more massive than the sun...

Researchers at the University of California, Irvine have discovered a new state of quantum matter. The state exists within a material that the team reports could lead to a new era of self-charging computers and ones capable of withstanding the challenges of deep space travel.

“It’s a new phase of matter, similar to how water can exist as liquid, ice or vapor,” said Luis A. Jauregui, professor of physics & astronomy at UC Irvine and corresponding author of the new paper in Physical Review Letters.

“It’s only been theoretically predicted—no one has ever measured it until now.”

This new phase is li...
