How Electrons, Repelling Each Other, Tie Knots in an Atomic Chain ⚡ экспресс

In a tight atomic chain, electron jostling gives birth to unbreakable knots that change the collective charge.

In a chain of carbon atoms, electron repulsion doesn't just push particles apart—it braids invisible knots that change the charge itself. This cunning soliton dance explains where perfect conducting edges in crystals come from—and how to tame them.
🎯 In everyday life, the electron charge is an indivisible constant. But inside matter, where electrons are crowded, their effective charge can change, like a coin passed from hand to hand losing or gaining a 'commission'. And in the described knots, this commission goes so far that the charge splits in half.
