Hermitian Hamiltonians are a fundamental concept in quantum mechanics, serving as the mathematical foundation for describing the energy and time evolution of quantum systems. They are named after the ...

An operator A with domain and range in a complex Banach space X is called hermitian if and only if iA generates a strongly continuous one-parameter group of isometries on X. It was shown previously ...

This Review Article outlines the exploration of the interplay between parity–time symmetry and non-Hermitian physics in optics, plasmonics and optomechanics.
