Polychromatic polarization microscope: bringing colors to a colorless world

Polychromatic polarization microscope: bringing colors to a colorless world.

Interference of two combined white light beams produces Newton colors if one of the beams is retarded relative to the other by from 400 nm to 2000 nm. In this case the corresponding interfering spectral components are added as two scalars at the beam combination. If the retardance is below 400 nm the two-beam interference produces grey shades only. The interference colors are widely used for an...

Colourless Mesons in a Polychromatic World

The limit of an infinite number of quark colours turns out to be a very useful starting point to understand many features of the strong interaction. The SU(NC) gauge theory simplifies considerably at NC →∞, while keeping the most essential properties of QCD. Choosing the coupling constant gs to be of O ( 1/ √ NC ) , i.e., taking the large–NC limit with αsNC fixed, there exists a systematic expa...

Bringing Semantic Services to Real-World Objects

The last few years have seen the emergence of two parallel trends: the first of such trends is set by technologies such as Near Field Communication, 2D Bar codes and RFID that support the association of digital information with virtually every object. Using these technologies ordinary objects such as coffee mugs or advertisement posters provide digital information that can be easily processed. ...
