unitary transformation group
The properties of strong coupling magnetoploron in the semiconductor quantum dot are investigated by the linear combination operator and unitary transformation methods.
We conduct a theoretical study on the properties of a bound polaron in a quantum well under an electric field using linear combination operator and unitary transformation methods, which are valid in the whole range of electron-LO phonon coupling.
In other words, The Hermiticity of a matrix is invariant under unitary transformations.
