TL;DR: It is found that there is is an optimal dimension that maximizes the secure information capacity whose value can be predicted analytically from the knowledge of only a few experimental parameters.

TL;DR: In this paper, it was shown that the atomic states can be described by wavefunctions calculated in the absence of an electromagnetic field when using the d · E (but not the p · A) form of the interaction Hamiltonian.

TL;DR: In this article, the authors describe a biosensor system that includes a first optical waveguide optically coupled to a light source, a first ring or disk resonator optically coupling to the first waveguide, and a monitoring system that signals the presence of a biological material based on a detected change in one or more transfer characteristics of the first ring/disk resonator.

TL;DR: This finding demonstrates that full reconstruction of all three components of nanoscale magnetic fields is possible without tilting the specimen and implements a recently developed holographic technique to manipulate the electron wavefunction, which gives free electrons an additional unbounded quantized magnetic moment along their propagation direction.

TL;DR: For a wide range of input powers, the output pulse widths of the dispersion-decreasing fiber are found to be as short as the input pulse widthS, whereas the output pulses of the constant-dispersion fiber are significantly larger.
