From Non Hermitian to Hermitian Matrix

In summary, a non-Hermitian matrix is a square matrix that is not equal to its conjugate transpose, and can be converted to a Hermitian matrix through the process of Hermitization. This is significant in quantum mechanics and other areas of physics, as Hermitian matrices have real eigenvalues, making mathematical analysis and interpretation easier. However, the resulting Hermitian matrix may have complex entries. Hermitization has applications in the study of physical observables in quantum mechanics and Hamiltonian systems in other areas of physics.

It depends om what you mean by "convert".

well probably you can write any matrix as a sum of a hermitian and an anti hermitian matrix and then you can throw away the anti hermitian part. just a throw away comment of something that is usually true.
 

1. What is a non-Hermitian matrix?

A non-Hermitian matrix is a square matrix that is not equal to its conjugate transpose. In other words, the entries of a non-Hermitian matrix are not symmetric about the main diagonal.

2. How is a non-Hermitian matrix converted to a Hermitian matrix?

A non-Hermitian matrix can be converted to a Hermitian matrix by adding its conjugate transpose to itself and then dividing by 2. This process is known as Hermitization.

3. What is the significance of converting a non-Hermitian matrix to a Hermitian matrix?

Converting a non-Hermitian matrix to a Hermitian matrix is important in quantum mechanics and other areas of physics, as Hermitian matrices have real eigenvalues. This allows for easier mathematical analysis and interpretation of the results.

4. Can any non-Hermitian matrix be converted to a Hermitian matrix?

Yes, any non-Hermitian matrix can be converted to a Hermitian matrix through the process of Hermitization. However, the resulting Hermitian matrix may have complex entries.

5. What applications does the concept of Hermitization have in science?

Hermitization is a fundamental concept in quantum mechanics, as it allows for the study of Hermitian operators which represent physical observables. It also has applications in other areas of physics, such as in the study of Hamiltonian systems.
