Cosmic microwave background (CMB) polarization observations will require superb control of systematic errors in order to achieve their full scientific potential, particularly in the case of attempts to detect the B modes that may provide a window on inflation. Interferometry may be a promising way to achieve these goals. This paper presents a formalism for characterizing the effects of a variet...

We present a study of single pulses from nine bright northern pulsars to investigate the behaviour of circular polarisation, V . The observations were conducted with the Effelsberg 100-m radio telescope at 1.41 GHz and 4.85 GHz and the Westerbork radio telescope at 352 MHz. For the first time, we present the average profile of the absolute circular polarisation |V | in the single pulses. We dem...

Using a classical ensemble method, nonsequential double ionization is predicted to exist with elliptical and circular polarization. Recollision is found to be the underlying mechanism, and it is only possible via elliptical trajectories.

The inter-band optical absorption in graphene characterized by its fine-structure constant has a universal value of 2.3% independent of the material parameters. However, for several graphenebased photonic applications, enhanced optical absorption in graphene is highly desired. In this work, we quantify the tunability of optical absorption in graphene via the Fermi level in graphene, angle of in...

Recently atomic magnetometers are one of the best tools in biomagnetic measurement such as magnetic field of brain and heart. In this paper, the technology of optically pumped atomic magnetometer based on circularly polarized light absorption pumping is described. We have been investigated a new method for measuring polarization effect in an alkali vapor based on polarized light transmission. I...

The potential of fluorescence-detected circular dichroism (FDCD) to extend the scope of the exciton chirality method is rooted in the increased sensitivity and selectivity of fluorescence as compared with absorbance measurements. In this paper, several practical aspects of FDCD are addressed with model compounds possessing a (1R,2R)-trans-1,2-cyclohexanediol skeleton and two chromophores attach...
