We undertake a pure-state analysis of a noise-dominated quantum event, namely spontaneous photon emission by an excited atom. While pure, the final state is nonseparably entangled. We calculate the participation ratio that provides a measure of the nonseparability, in the context of Schmidt-type analysis. The Schmidt modes serve as pairwise ''pointer''… (More)
We employ an arrangement of polarization analyzer loops to derive several simple Bell inequalities and then discuss the violation of one of them in light of quantum and classical interpretations of the data recorded.
We identify classical light fields as physical examples of nonquantum entanglement. A natural measure of degree of polarization emerges from this identification, and we discuss its systematic application to any optical field, whether beamlike or not.
We predict new end-of-pulse behavior in high-field atomic double ionization. Calculations of atomic electron trajectories in short intense laser pulses confirm our analysis of elliptical polarization. We exhibit a four-band structure in ion momentum distributions under various ellipticities, and predict that sequential and nonsequential double ionization… (More)
The degree of elliptical polarization of intense short laser pulses is shown to be related to the timing of strong-field nonsequential double ionization. Higher ellipticity is predicted to force the initiation of double ionization into a narrower time window, and this "pins" the ionizing field strength in an unexpected way, leading to the first… (More)
We present coincidence momentum measurements that contradict the independent electron assumption for elliptically polarized laser pulses. This shows that recollision is not the only reason for electron correlation in strong field double ionization.

We analyze the propagation of fast-light pulses through a finite-length resonant gain medium both analytically and numerically. We find that intrinsic instabilities can be avoided in attaining a substantial peak advance with an ultrashort rather than a long or adiabatic probe.
