Spatial dimensionality of a system determines the types of phenomena it can exhibit. A new analysis shows how the dimensionality of a single spin-1/2 particle can be effectively increased by applying a drive with two incommensurate frequencies, thereby dynamically inducing an exotic topological phase of matter.

2. Selectivity. The selective properties of a frequency converter are assessed by its amplitude-frequency characteristic. However, it should be noted that in frequency converters, in contrast to selective amplifiers, this characteristic is determined not only by the type of the amplitude-frequency characteristic of the load, but also by the features of the conversion process.

The (^{87}) Rb atoms used in our experiments emit write-out photons at a wavelength of 795 nm, which have a transmission loss in the fibre of about 3.5 dB/km. We use quantum frequency conversion techniques (QFC) to coherently convert the photon wavelength to 1342 nm (O-band, loss (sim 0.3) dB/km) to reduce the loss. This chapter briefly explains the …
