Light Matter Interaction: Observable phenomena that can not be predicted by the standard formalism of QM
Speaker:Nimrod Moiseyev (Technion - Israel Institute of Technology )
Abstract:The non-hermitian formalism of quantum mechanics enables one to solve problems which are extremely hard to solve and often even impossible to solve within the framework of the standard formalism of quantum mechanics. In this talk I will focus on a situation where in non-hermitian quantum mechanics two eigenvalues and their corresponding eigenfunctions are degenerated eigenvalues and states, respectively. We will discuss the effect of this "accidental" situation (which cannot happen in the standard formalism of quantum mechanics) on different type of observable phenomena. We will show how there are observable phenomena that can be predicted by the non-hermitian formalism of quantum mechanics in light matter interactions. Either in propagation of light in waveguides or when atoms or molecules or nanostructures interact with laser fields.
