Atomtronics: A new phase

Just as NASA engineers test new rocket designs in computer studies before committing themselves to full prototypes, so physicists will often model matter under various circumstances to see whether something new appears. This ...

A new quantum approach to solve electronic structures of complex materials

If you know the atoms that compose a particular molecule or solid material, the interactions between those atoms can be determined computationally, by solving quantum mechanical equations—at least, if the molecule is small ...

Scientists predict state of matter that can conduct both electricity and energy perfectly

Three scientists from the University of Chicago have run the numbers, and they believe there may be a way to make a material that could conduct both electricity and energy with 100% efficiency—never losing any to heat or ...

Entering the strange world of ultra-cold chemistry

Researchers at the Georgia Institute of Technology have received a $900,000 grant from the U.S. Air Force Office of Scientific Research (AFOSR) to study the unusual chemical and physical properties of atoms and molecules ...

Researchers propose improvements to recommendation engines based on particle physics

(Phys.org)—A trio of researchers has uploaded a paper they've written to the preprint server arXiv describing a way to improve recommendation engines, using principles from particle physics. The idea, they say, is to use ...

Rare decay of the Higgs boson may point to physics beyond the Standard Model

Particle physicists have detected a novel decay of the Higgs boson for the first time, revealing a slight discrepancy in the predictions of the Standard Model and perhaps pointing to new physics beyond it. The findings are ...

The first model for capturing and condensing light under realistic conditions

Quantum particles can be divided into two types: fermions and bosons. When cooled down to near-absolute zero temperatures, bosons can condense together into a collective state of matter called a Bose-Einstein condensate where ...

A model that can predict the exact quasi-particle properties of heavy Fermi polarons

Physicists studying quantum many-body physics very rarely reach exact solutions or conclusions, particularly in more than one dimension. This is also true for the Fermi polaron problem, describing instances in which the many-body ...

First-ever evidence of exotic particles in cobalt monosilicide

Anew study provides the first evidence of exotic particles, known as fourfold topological quasiparticles, in the metallic alloy cobalt monosilicide. Published in the Proceedings of the National Academy of Sciences, this comprehensive ...

One theory beyond the standard model could allow wormholes that you could actually fly through

Wormholes are a popular feature in science fiction, the means through which spacecraft can achieve faster-than-light (FTL) travel and instantaneously move from one point in spacetime to another. And while the General Theory ...
