graphene's whizzy electrons grind to a halt

Categories: Comparisons

An example of metaphor used in science journalism:

"Theory also predicted that under the influence of these larger moiré superlattices, at certain 'magic angles', graphene's headline-grabbing whizzy electrons would effectively grind to a halt. With zero kinetic energy their behaviour is then governed almost exclusively by Coulomb interactions with other electrons, rendering strongly correlated electron effects like superconductivity."
