Exact Canonical Dressing of Two-Level Atoms by Two-Photon Processes
The aim of this paper is to present new exact results on the subject of dressing of a two-level atom by an electromagnetic field.
Quantum Disorder in Macroscopic Systems of Interacting Atoms and Radiation Fields
The linear interaction between a system of two-level atoms and an electromagnetic field can be described as taking place through a number of elementary acts in which photons are absorbed or emitted, while atoms change their states. It is conceivable that these processes tend to modify the original statistical properties characteristic of the atomic system and of the electromagnetic field at t = 0, when we assume that the interaction is “turned on”. The problem is of conceptual importance, and might become of practical importance in connection with laser processes in unusual ranges of frequency. In fact, it has recently received increasing attention in the case of one-photon interactions [1]…
Squeezing in a two-photon Dicke hamiltonian
Abstract The single-mode, two-level atom Dicke hamiltonian with two-photon atom-field coupling is treated exactly and it is shown to yield a certain degree of squeezing in the field variables. This result is briefly discussed in connection with the previously shown absence of squeezing in the two-photon laser model.
L’educazione personalizzata come correlato epistemologico della didattica inclusiva
Il contributo muove dallo studio delle possibili connessioni epistemiche tra l’Educazione personalizzata e la Didattica inclusiva e, al contempo, intende pagare un tributo al Prof. G. Zanniello (1997) cui va il merito di aver fatto conoscere in Italia il sistema dell’educazione personalizzata di Victor García Hoz prima che l’espressione “personalizzazione educativa” fosse inserita per la prima volta in una legge scolastica italiana (n. 53/2003).
