Quantum mechanics describes the microscopic properties of nature in a regime where classical mechanics no longer applies. It explains phenomena such as the wave-particle duality, quantization of energy, and the uncertainty principle and is generally used in single-body systems. Use the quantum-field-theory tag for the theory of many-body quantum-mechanical systems.

How can increasing the speed and/or mass of a particle reduce, not increase, it's frequency?
"electrons' frequency" does sound ambiguous. It should be the plasma frequency.
For example explained in here:
Testing one of those promising mechanisms became possible by operating in the relativ …

Does $U^T U$ have real eigenvectors if $U$ is unitary?
To fix the Mathematica code in Emilio's answer I believe it should be CircularUnitaryMatrixDistribution instead of GaussianUnitaryMatrixDistribution.
GaussianUnitaryMatrixDistribution[σ,n], also r …
