Scientists have made an important step toward developing computers advanced enough to simulate complex natural phenomena at the quantum level. While these types of simulations are too cumbersome or outright impossible for ...
The data centers and high-performance computers that run artificial intelligence programs, such as large language models, aren't limited by the sheer computational power of their individual nodes. It's another problem—the ...
An optical isolator developed at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) could drastically improve optical systems for many practical applications.
Using novel materials that have been widely studied as potential new solar photovoltaics, researchers at MIT have shown that nanoparticles of these materials can emit a stream of single, identical photons.
Can dark matter interact with photons and influence atomic structure? A case for optical atomic clocks: Two different types of such clocks were compared at the Physikalisch-Technische Bundesanstalt (PTB) within the scope ...
A new publication by the PHENIX Collaboration at the Relativistic Heavy Ion Collider (RHIC) provides definitive evidence that gluon "spins" are aligned in the same direction as the spin of the proton they're in. The result, ...
Paderborn researchers from the Department of Physics and the Institute for Photonic Quantum Systems (PhoQS) have succeeded in manufacturing quantum dots—nanoscopic structures where the material's quantum properties come ...
Nanophotonics and topology have generated significant interest due to the unique properties they offer. One area of focus is the investigation of topological edge states (TESs). These states have captured widespread attention ...
AI, machine learning, and ChatGPT may be relatively new buzzwords in the public domain, but developing a computer that functions like the human brain and nervous system—both hardware and software combined—has been a decades-long ...
In 2021, lanthanide-doped nanoparticles made waves—or rather, an avalanche—when Changwan Lee, then a Ph.D. student in Jim Schuck's lab at Columbia Engineering, set off an extreme light-producing chain reaction from ultrasmall ...
