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. A Course in Quantum Many-Body Theory: From Conv...
As he flipped to Chapter 4, "The Green’s Function Method," the library around him began to blur. It wasn't a dizzy spell. The wooden table began to lose its "woodness," dissolving into a shimmering lattice of carbon atoms. His coffee cup became a probability cloud of ceramic shards.
