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...
The Sun Is Stranger Than Astrophysicists Imagined
The sun radiates far more high-frequency light than expected, raising questions about unknown features of the sun’s magnetic field and the possibility of even more exotic physics. A decade’s worth...
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...
The Near-Magical Mystery of Quasiparticles
...Das Sarma is undeterred. “I guarantee you the Majorana will be seen, because its theory is pristine. This is an engineering problem; this is not a physics problem,” he said....
How Gravity Is a Double Copy of Other Forces
...it’s rooted in a different way of understanding gravity.” Gravity Versus the Rest On one side of the fundamental physics divide stand the electromagnetic force, the weak force and the...
A New Map of All the Particles and Forces
...interactions. Together, the equations formed a succinct theory now known as the Standard Model of particle physics. The Standard Model is missing a few puzzle pieces (conspicuously absent are the...
How Bell’s Theorem Proved ‘Spooky Action at a Distance’ Is Real
...about the laws of physics. So when Albert Einstein and two colleagues showed in 1935 that quantum mechanics permits “spooky action at a distance,” as Einstein put it, this feature...
The ‘Weirdest’ Matter, Made of Partial Particles, Defies Description
...some of the grittiest problems in fundamental physics. Fractons are quasiparticles — particle-like entities that emerge out of complicated interactions between many elementary particles inside a material. But fractons are...
Will Better Superconductors Transform the World?
...would win Kamerlingh Onnes the 1913 Nobel Prize in Physics. [Theme ends] But more importantly, it marked the start of an unresolved quest for material that maintains perfect conductivity at...
