From the post "Another Take On Discrete",
x=e−A(x−1)n2
where x=1 is an immediate solution. It is a unit circle onto which n cycles of wavelength λ can be packed, where n∈Z+, 0<n<n∞, and n∞→∞.
2π.x=2π=nλ
Although not a "natural" solution for a particle of unit radius (1 m in SI units), it is a valid solution to the equation for ψ. If a particle can be sufficiently isolated (1 m radius), then it can be a high frequencies, ultra-broadband, discrete frequency resonator.
And be made to resonate at,
f=nc2π
for n=1,2,3...
Very interesting.
