In this paper, we discuss the statistical properties of London-modified coherent states that were introduced in order to build up a resolution of the identity for London coherent states. The resolution to the identity is realized by the application of an operator to the London cohrent states. Next we find the Mandel-Q parameter that shows that there exist sub-Poissonian behaviour for a large interval of amplitudes, look at their behaviour in phase space through the Husimi-Q function and study their interaction with a two-level atom. We show that their oscillating photon distributions are responsible for the ringing revival behaviour shown by the atomic inversion. [ABSTRACT FROM AUTHOR]
