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...
A Dark Dimension Could Link Two of the Universe’s Great Unknowns
...of particle physics. In the new model, both the energy density of dark energy and the mass of dark matter change in concert. Another recent study imagines something similar. According...
How Physicists Track and Trap the Elusive Neutrino
...during a radioactive process called beta decay. Something was missing, and there was no known physics to explain it. Then in 1930, the Austrian physicist Wolfgang Pauli proposed a radical...
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...
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...
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...
Evidence Found for a New Fundamental Particle
...neutrino physicist at the Massachusetts Institute of Technology and a member of the MiniBooNE collaboration. The existence of a sterile neutrino would revolutionize physics from the smallest to the largest...
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...
Analog vs. Digital: The Race Is On To Simulate Our Quantum Universe
...can solve the equations of physics only at those points, circumventing the impossible task of simulating a field’s true infinite resolution. But even with this approximation, classical computer simulations hit...
