State of light

The problem of solvent absorption can be overcome by measuring the change in reflectivity of the electrode either by (a) modulating the state of light polarization between p-polarized and s-polarized radiation, or (b) using p-polarized radiation and taking spectra at two different electrode potentials.

The Raman spectra of arsenious chloride,2 in the liquid and gaseous states, of light and heavy arsine3 and of sodium arsenite and sodium arsenate,4 have been examined and frequencies obtained. The Raman spectra of the chloride and bromide in solution in ether or benzene consist of the spectra of the pure solute and pure solvent only, indicating that chemical combination does not occur in the solution.6 With solutions in methyl and ethyl alcohols, the frequencies of the latter are unchanged, but those of arsenious chloride are lowered somewhat.6...

How do we describe the polarization states of light, which are not polarized parallel to one of the main crystalline axes We have to look at the different components of E parallel to the main axes, evaluate their propagation and at the end of the optical path add them up to the resulting beam. 

These correlations between Stokes and anti-Stokes pulses allow for the conditional preparation of the anti-Stokes pulse with intensity fluctuations that are suppressed compared with classical light. In order to quantify the performance of this technique, we measured the second-order intensity correlation function giis MS ) and mean number of photons fi for the anti-Stokes pulse conditioned on the detection of ns photons in the Stokes channel (see Fig. 4). (For classical states of light, (f1] > 1, whereas an ideal Fock state with n photons has anti-Stokes photons grows linearly with ns, while (AS1) drops below unity, indicating the nonclassical character of the anti-Stokes photon states. In the presence of back-ground counts, gks (AN) does not increase monotonically with ns, but instead exhibits a minimum at ns = 2. The Mandel Q parameter [Mandel 1995] can be calculated using = n f((jns (AS) — 1) from these measurements we... 

We conclude that large ensemble of atoms are well suited systems to store non-classical quantum states of light. They are not more sensitive to decoherence than single particle systems. Furthermore in the presence of a sufficiently large energy gap between appropriate collective states ensembles can lead to a suppression of decoherence much below the level possible in single-particle systems.

Since the amplification is accompanied by exponential increase of noise transferred from the phonon reservoirs, the oscillating dynamics of region 3 is optimal for the generation of nonclassical states of light in the coupler. 

As mentioned above, the localised model used to describe the quantum states of light atoms in a heavy atom matrix is the Simple Harmonic Oscillator [7]. 

Similar treatments of the general subject of the excited states of light nuclei, including both experimental and theoretical aspects, are given in [i] to [4].
