正文提要
An electron is supposed to be indivisible. It carries one fundamental unit of electric charge, and every electron is exactly the same. But under extreme conditions, large numbers of electrons act together and give rise to new quantum objects called quasiparticles. These act as if they carry only a fraction of an electron's charge, making them one of the strangest phenomena in modern physics.
