Phase-dependent spectra in a driven two-level atom

One of the most striking features of the interaction of a monochromatically driven two-level atom interacting with a squeezed vacuum is the existence of phasedependent features in resonance fluorescence. The relative heights and widths of the spectrum triplet vary greatly with the phase of the squeezed vacuum [1,2]. In addition, some peaks may show subnatural linewidths. Although these effects ...

States insensitive to the Unruh effect in multi-level detectors

We give a general treatment of the spontaneous excitation rates and the non-relativistic Lamb shift of constantly accelerated multi-level atoms as a model for multi-level detectors. Using a covariant formulation of the dipole coupling between the atom and the electromagnetic field we show that new Raman-like transitions can be induced by the acceleration. Under certain conditions these transiti...

the effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test

in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...

The Schwinger Mechanism, the Unruh Effect and the Production of Accelerated Black Holes

We prove that the Heisenberg-Euler-Schwinger mechanism –pair creation in a constant electric field– and its radiative corrections imply the Unruh effect, i.e. the thermalisation of accelerated systems at temperature a/2π where a is the acceleration. More precisely, the properties of the amplitudes for pair creation under crossing symmetry and CPT are sufficient to deduce the Unruh effect. Furth...

The Unruh effect revisited

We give a complete and rigorous proof of the Unruh effect, in the following form. We show that the state of a two-level system, uniformly accelerated with proper acceleration a, and coupled to a scalar bose field initially in the Minkowski vacuum state will converge, asymptotically in the detector’s proper time, to the Gibbs state at inverse temperature β = 2π a . The result also holds if the f...
