Scientists have directly watched angular momentum move through a crystal for the very first time — and discovered a bizarre twist along the way. Using ultra-powerful terahertz laser pulses, ...

A centimeter-sized crystal has revealed clear signs of quantum entanglement, showing that large, everyday objects can display surprisingly deep quantum behavior. The discovery could help solve the ...

MIT physicists have synthesized a new family of bulk crystals whose electrons behave as though they move in an effectively four-dimensional “superspace,” rather than being fully described by the three ...
