degeneracy

1 8.7
A situation when different states have the same value, for example the same energy level

  • However, even assuming coding degeneracy, the number is still likely to be super-low.
  • degeneracy pressure
  • electron degeneracy

M doesn't change the energy, it gives degeneracy, right.

Examples

  • But here you start to see degeneracies, multiple degeneracies.

  • In particular, there's something called electron degeneracy pressure.

  • The signature of reaching quantum degeneracy is dramatic.

    Academic text (1999)
  • So is it the case that mirror symmetry guaranteed degeneracy in any situation?

  • In most cases, the resulting remnant is a neutron star supported by the degeneracy pressure of its constituents.

  • The basis for this "theorem" is the degeneracy of the genetic code: a given polypeptide sequence can be encoded by different DNA sequences.

    Academic text (1996)
  • The nonabelian nature of the Moore-Read state stems from the remarkable collective degeneracy of its quasiparticles.

    Academic text (2005)
  • The Harvard collaboration derived J(e) from the behavior of PS at the degeneracy between S and T+.

    Academic text (2006)
  • An applied magnetic field of 10 tesla lifts the degeneracy between the spin-up and spin-down ground-state levels by an amount larger than the thermal energy at the experiment's temperature of 300 mK.

    Academic text (2004)
  • In mathematics, degeneracy occurs when two solutions yield the same minimal value in an optimization problem.

Morphology

degeneracy = degenerate (semi-transparent) = degenerate + acy

Formally a nominalization of 'degenerate', but the scientific/mathematical sense is specialized and not directly deducible by general learners from the adjective.

Etymology

Degeneracy comes from the parts de- 'down' and genus 'kind', which you also find in generation and gene. In science and math, that idea helps: different states are not different kinds but the same, so they share one value or level.
