Free Space Ranging Utilizing Chaotic Light

Light Modes of Free Space

Light-matter interaction in free space

We review recent experimental advances in the field of efficient coupling of single atoms and light in free space. Furthermore, a comparison of efficient free space coupling and strong coupling in cavity quantum electrodynamics (QED) is given. Free space coupling does not allow for observing oscillatory exchange between the light field and the atom which is the characteristic feature of strong ...

Chaotic free-space laser communication over a turbulent channel.

The dynamics of errors caused by atmospheric turbulence in a self-synchronizing chaos-based communication system that stably transmits information over an approximately 5 km free-space laser link is studied experimentally. Binary information is transmitted using a chaotic sequence of short-term pulses as a carrier. The information signal slightly shifts the chaotic time position of each pulse d...

Cause Chlamydiosis refers to an infection with organisms of the genus Chlamydia sp., which are bacteria that live within animal cells. Chlamydia psittaci is the species generally associated with this disease in birds. The severity of the disease differs by the strain of C. psittaci and the susceptibility of different species of birds. As a result, chlamydiosis may range from an inapparent infec...

Fences catch free-ranging lipids

surface is crisscrossed with picket fences made of immobile transmembrane proteins. Until now, single-particle tracking (SPT) has been too slow to provide a high-resolution view of lipid diffusion. In an impressive technical achievement, the authors developed a SPT technique with 25s resolution, and then used it to follow the diffusion of a nonraft lipid in a cell membrane. The lipid molecule w...
