Here, the electrons were no longer individuals. They were a mosh pit, a tangled web where one particle's movement sent a violent ripple through every other soul in the room.

The heavy, blue-spined textbook had lived on the bottom shelf of the university library for a decade, its title— A Course in Quantum Many-Body Theory: From Conventional Systems to Strongly Correlated Matter —acting as a natural deterrent to anyone looking for a light read. Hours later, a librarian tapped Arthur on the shoulder
"It’s not chaos," Arthur whispered, watching a Cooper pair glide past him in a perfect, superconducting slipstream. "It’s choreography." To his left, a "conventional system" of electrons
