Twisting ultra-thin crystals creates controllable quantum light sources
In a paper published in Science Advances, researchers at the University of Technology Sydney (UTS) in collaboration with the University of Minnesota and Kyung Hee University have found a new way to…
Tiny swimmers in liquid light mysteriously move against the current
Superfluids are intriguing states of matter in which particles behave like a giant collective wave, allowing them to flow without any friction. When this fluid flows past a fixed obstacle at a…
Scientists observe all five phases of quantum localization in one system
Physicists in China have observed five phases in localization physics within a single quantum system. Using an advanced photonic platform, the team, led by Yucheng Wang and Jingyun Fan at the…
Einstein’s “biggest blunder” may finally have an explanation
Scientists have uncovered a surprising connection between quantum gravity and an exotic quantum state of matter that could explain why the universe isn’t expanding wildly fast. The study suggests…
Ultrafast nonadiabatic dynamics of tetraphenylsubstituted nitrogen-based heterocycles
arXiv:2604.16897v2 Announce Type: replace
Abstract: Tetraphenylpyrazine (TPP) and 2,3,4,5-tetraphenyl-1H-pyrrole (TePP) are closely related heterocycles bearing four phenyl substituents, whose…
