Why This Universe? A New Calculation Suggests Our Cosmos Is Typical.
...for Theoretical Physics in Waterloo, Canada, for the same reason that air spreads evenly throughout a room: Weirder options are conceivable, but exceedingly improbable. The universe “may seem extremely fine-tuned,...
A New Theory for Systems That Defy Newton’s Third Law
...systems are elegantly described with statistical mechanics, the branch of physics that explains how collections of objects behave. This allows researchers to fully model the conditions that give rise to...
Eternal Change for No Energy: A Time Crystal Finally Made Real

A Mathematician’s Unanticipated Journey Through the Physical World
...quantum physics. It’s a potpourri of insights that cohere around the positive Grassmannian, and around the unique mind that generated them. “Lauren is one of these people who thinks so...
Physicists Pin Down Nuclear Reaction From Moments After the Big Bang
...physics, nuclear physics, cosmology and astronomy,” he said. The reaction involves deuterium, a form of hydrogen consisting of one proton and one neutron that fused within the cosmos’s first three...
Inside the Knotty World of ‘Anyon’ Particles
A new class of quantum particle is about to emerge from the tangled considerations of quantum statistics. [No Caption] I. Prior to the emergence of quantum mechanics, fundamental physics was...
How the Hidden Higgs Could Reveal Our Universe’s Dark Sector
...particle physics. But it’s possible that the LHC has been producing such pivotal new particles all along, and that we’re just not seeing them. “The core of the story,” said...
‘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...
