Elementary theory of the twisted atom

In this talk I will discuss the basic theory of the twisted quantum state of a complex quantum system such as an atom. Within the proposed framework I will consider two basic QED processes: emission of the photon by the twisted atom due to the electron transition and absorption of the twisted photon by a bound electron in the moving atom. I will provide some experimental scenarios where the effects associated with the twisted atomic structure can be observed.
