Team develops method for trapping elusive electrons

Graphene's unique 2-D structure means that electrons travel through it differently than in most other materials. One consequence of this unique transport is that applying a voltage doesn't stop the electrons like it does ...

A new symmetry-broken parent state discovered in twisted bilayer graphene

In 2018 it was discovered that two layers of graphene twisted one with respect to the other by a "magic" angle show a variety of interesting quantum phases, including superconductivity, magnetism and insulating behaviors. ...

Physicists publish worldwide consensus of muon magnetic moment calculation

For decades, scientists studying the muon have been puzzled by a strange pattern in the way muons rotate in magnetic fields, one that left physicists wondering if it can be explained by the Standard Model—the best tool ...

How growth of the scientific enterprise influenced a century of quantum physics

Austrian quantum theorist Erwin Schrödinger first used the term "entanglement," in 1935, to describe the mind-bending phenomenon in which the actions of two distant particles are bound up with each other. Entanglement was ...

New discovery helps close the gap towards optically-controlled quantum computation

Scientists at Ames Laboratory, Brookhaven National Laboratory, and the University of Alabama Birmingham have discovered a light-induced switching mechanism in a Dirac semimetal. The mechanism establishes a new way to control ...
