The term Fermi point has two applications but refers to the same phenomena (special relativity):
- Fermi point (Quantum Field Theory)
- Fermi point (Nanotechnology)
For both applications count that the symmetry between particles and anti-particles in weak interactions is violated:
At this point the particle energy E = cp is zero.
In nanotechnology this concept can be applied to electron behavior. An electron when as single particle is a Fermion obeying the Pauli exclusion principle.

Famous quotes containing the word point:
“The striking point about our model family is not simply the compete-compete, consume-consume style of life it urges us to follow.... The striking point, in the face of all the propaganda, is how few Americans actually live this way.”
—Louise Kapp Howe (b. 1934)
