First Map Made of a Solid’s Secret Quantum Geometry | Quanta Magazine

Physicists recently mapped the hidden shape that underlies the quantum behaviors of a crystal, using a new method that’s expected to become ubiquitous.

Famously, at the quantum scale, particles can be in multiple possible locations at once. A particle’s state spreads out like a wave, peaking where the particle is likely to be found. When you measure its position, this spread-out state, known as a wave function, transforms into a single definite location. The full shape of the wave function long evaded detection, since trying to measure it will…
