Rydberg states of atoms might provide many solutions.  These highly excited states have very large outer orbitals, the size of which scales as n²  quantum number resulting in some extreme properties.

While thermodynamic systems are generally treated by averaging over many body systems, we scale such a system down to the ultimate limit of a single quantum particle. We analyze an experimental scheme for a nano-heat engine using a single ion as working gas. An Otto cycle may be implemented by confining the ion in a linear Paul trap with tapered geometry and coupling it to engineered reservoirs. Are the classical thermodynamic laws, based on the dynamics of large ensembles, still valid for a single particle? Do they have to be modified when employing quantum reservoirs?

Chiral molecules of opposite handedness interact with circularly polarized light in different ways. The resulting effects, such as optical rotation and circular dichroism are established measurables for quantifying molecular chirality.
