Resumo
Here we investigate some general properties of the so-called even circular state
(ECS) produced in a cavity, consisting of a superposition of N coherent states |αk
(k = 1, 2, . . . , N) with the same |αk |. Several special states may emerge from this kind of
superposition: in particular, when 1 (e|αk |2/N)N 4N a Fock state with N quanta is
produced, whereas when (e|αk |2/N)N 1 one gets a vacuum state. We analyse the atomic
scattering the ECSs produce when two-level atoms go through the cavity and also the
non-classical depth of these states.
