‘Quantum Atmospheres’ May Reveal Secrets of Matter
...a ceramic-like insulator. Topological insulators have drawn attention for their unusual physics as well as for their potential use in quantum computers and so-called spintronic devices, which utilize electrons’ spins...
Real-Life Schrödinger’s Cats Probe the Boundary of the Quantum World
...same, these exotic objects are worth heeding, because they show with unprecedented clarity that quantum mechanics is not just the physics of the extremely small. “Schrödinger’s kittens,” loosely speaking, are...
Why Gravity Is Not Like the Other Forces
...these possibilities remain conjectural and incompletely understood. A working quantum theory of gravity is perhaps the loftiest goal in physics today. What is it that makes gravity unique? What’s different...
Growing Anomalies at the Large Hadron Collider Raise Hopes
...physics — the reigning set of equations describing the subatomic world. Taken alone, each oddity looks like a statistical fluctuation, and they may all evaporate with additional data, as has...
Novel Architecture Makes Neural Networks More Understandable
...Wetzel, a researcher at the Perimeter Institute for Theoretical Physics. “When we scale them up to larger data sets, nothing can compete.” And yet, all this time, neural networks have...
Physicists Use Quantum Mechanics to Pull Energy out of Nothing
...battery — but all he has access to is empty space. Fortunately, his friend Alice has a fully equipped physics lab in a far-off location. Alice measures the field in...
Neutrinos Suggest Solution to Mystery of Universe’s Existence
...Model of particle physics, every particle has a mirror-image particle that carries the opposite electrical charge — an antimatter particle. When matter and antimatter particles collide, they annihilate in a...
How Is Flocking Like Computing?
...exhibited. When we first measured these properties, it seemed like the individuals were defying the laws of physics. The information was percolating so quickly. And in the, sort of, early...
High-Temperature Superconductivity Understood at Last
...in a particular direction, like a quantum-size magnet. The late Philip Anderson, an American Nobel laureate and all-around legend in condensed matter physics, put forth a theory just months after...
