Web"Degeneracy" here just means that there are more than one quantum states with the same sharply-defined energy. For example, there can be a state where an electron is … In quantum mechanics, an energy level is degenerate if it corresponds to two or more different measurable states of a quantum system. Conversely, two or more different states of a quantum mechanical system are said to be degenerate if they give the same value of energy upon measurement. The number of … See more The possible states of a quantum mechanical system may be treated mathematically as abstract vectors in a separable, complex Hilbert space, while the observables may be represented by linear See more If two operators $${\displaystyle {\hat {A}}}$$ and $${\displaystyle {\hat {B}}}$$ commute, i.e. $${\displaystyle [{\hat {A}},{\hat {B}}]=0}$$, … See more Degeneracies in a quantum system can be systematic or accidental in nature. Systematic or essential degeneracy This is also called a … See more The degeneracy in a quantum mechanical system may be removed if the underlying symmetry is broken by an external perturbation. This causes splitting in the degenerate energy levels. This is essentially a splitting of the original irreducible … See more This section intends to illustrate the existence of degenerate energy levels in quantum systems studied in different dimensions.
