Two-dimensional Liquid Helium System
The Quantum Dynamics Unit traps a 2-D layer of electrons in liquid helium, held inside a sealed chamber and cooled to nearly absolute zero. Inside the chamber, a metal plate and spherical mirror on the top reflect microwave light (the red beam), and thus form a microwave cavity (resonator). The trapped microwaves interact with the electrons floating on the liquid helium.
