Laughlin: incompressible quantum Hall fluid

What changed

Proposed incompressible quantum-fluid wavefunctions and fractionally charged excitations.

Scientific scope

The record is Laughlin’s sole-author 1983 Physical Review Letters paper. It does not absorb the experimental discovery, later hierarchy/composite-fermion theories or all fractional topological phases.
