Excitation transport through Rydberg dressing

We show how to create long-range interactions between alkali atoms in different hyperfine ground states, with the goal of coherent quantum transport. The scheme uses off-resonant dressing with atomic Rydberg states. We demonstrate coherent migration of electronic excitation through dressed dipole–dipole interaction by full solutions of models with four essential states per atom and give the str...

IPsec-Protected Transport of HDTV over IP

Bandwidth-intensive applications compete directly with the operating system’s network stack for CPU cycles. This is particularly true when the stack performs security protocols such as IPsec; the additional load of complex cryptographic transforms overwhelms modern CPUs when data rates exceed 100 Mbps. This paper describes a network-processing accelerator which overcomes these bottlenecks by of...

Subradiance in a Large Cloud of Cold Atoms.

Since Dicke's seminal paper on coherence in spontaneous radiation by atomic ensembles, superradiance has been extensively studied. Subradiance, on the contrary, has remained elusive, mainly because subradiant states are weakly coupled to the environment and are very sensitive to nonradiative decoherence processes. Here, we report the experimental observation of subradiance in an extended and di...

Symmetry-protected transport in a pseudospin-polarized waveguide

If a system possesses a spin or pseudospin, which is locked to the linear momentum, spin-polarized states can exhibit backscattering-immune transport if the scatterer does not flip the spin. Good examples of such systems include electronic and photonic topological insulators. For electromagnetic waves, such pseudospin states can be achieved in metamaterials with very special artificial symmetri...
