In recent years intense laser fields have become more available over a frequency range extending from the infrared to the ultraviolet in the form of short pulses. In the low frequency regime where the photon energy is much lower than the ionisation potential, the advent of high …

In this thesis, we investigate the collective electron dynamics in single and coupled superlattice systems under the influence of a DC electric field. Firstly, we illustrate that Bloch oscillations suppress electron transport and the resulting charge domains form self-sustained …
This thesis deals with the ground-based fully polarimetric system of its design and construction arrangement. The asserted system is conducted for short range operation and adequately determines the complete polarimetric images of various natural targets. The system will be oper…
The role of frequency in language acquisition has been a controversial issue for a long time. In usage-based theories, frequency of input is claimed to be a very influential factor in the process of language acquisition. However, there has been relatively little research on freq…
