"The cool world of electrons trapped in a magnetic vortex"

When electrons in two dimensions are cooled to near absolute zero and exposed to a strong magnetic field, the repulsive Coulomb interaction traps them into quantized magnetic vortices to create topological particles called composite fermions. These are responsible for the unexpected phenomenology of this state, including the celebrated fractional quantum Hall effect.
