Phys.org / AI could be trapped in a 'Carbon Valley' unless action is taken soon
AI is growing fast, and keeping up means building more data centers, manufacturing advanced chips and powering the tech behind it. All of that comes with a carbon cost. AI advocates claim that in the long run, AI will save ...
Phys.org / Quantum Hall effect gains a new twist in graphene moiré systems
Physicists have long been drawn to the nonlinear Hall effect: a subtle variant of the classical Hall effect, in which an electric voltage appears perpendicular to a current flowing through a material. Unlike its classical ...
