1. Quantum mechanical properties of Bessel EM modes and their effect on atomic systems Rocio Jáuregui Renaud Instituto de Física, Universidad Nacional Autónoma de México

2. OBJECTIVES Bessel EM modes are studied within the general framework of quantum optics. The basic dynamical operators are identified and their algebraic properties are studied. As a mean to measure these dynamical proper- ties, the transition probability for the emission of a Bessel photon by an atomic system is calculated within first order perturbation theory. This permits to analyze the feasibility of observing new rotational effects of twisted light on atoms.

3. Bessel modes are propagation invariant waves of cylindrical symmetry

4. They can be generated with holograms, optical light modulators and other optical dispositives like axicons.
