Another example of nearly synonymous doublets is aperture and overture (the commonality behind the meanings is "opening"). Doublets may also develop contrasting meanings, such as the terms host and guest, which come from the same PIE word * gʰóstis and already existed as a doublet in Latin, and then Old French, [2] before being borrowed into ...
The best known example is a spin multiplet, which describes symmetries of a group representation of an SU(2) subgroup of the Lorentz algebra, which is used to define spin quantization. A spin singlet is a trivial representation, a spin doublet is a fundamental representation and a spin triplet is in the vector representation or adjoint ...
A theoretical study found about one earthquake in 15 (~7%) to be a doublet (using a narrow criterion of "doublet"), [15] but also found that in the Solomon Islands six of 57 M ≥ 6.0 earthquakes were doublets, and 4 of 15 M ≥ 7.0 earthquakes, showing that approximately 10% and 25% of those quakes were doublets. [16] Doublet earthquakes pose ...
In quantum mechanics, a doublet is a composite quantum state of a system with an effective spin of 1/2, such that there are two allowed values of the spin component, −1/2 and +1/2. Quantum systems with two possible states are sometimes called two-level systems .
The ability of positronium to form both singlet and triplet states is described mathematically by saying that the product of two doublet representations (meaning the electron and positron, which are both spin-1/2 doublets) can be decomposed into the sum of an adjoint representation (the triplet or spin 1 state) and a trivial representation (the ...

In spectroscopy and quantum chemistry, the multiplicity of an energy level is defined as 2S+1, where S is the total spin angular momentum. [1] [2] [3] States with ...
