Correlation Effect of Two Donors in a Nano Dot under the Influence of Magneticfield

Magnetic field induced binding energy of two donors in a parabolic GaAs/AlGaAs nano dot is reported. The calculations are carried out using variation ansatz within the single band effective mass approximation. The binding energy is estimated for different inter-impurity distances in the presence of magnetic field. The correlation effect of two donors is introduced through the wave function. It is found that inter-impurity distance, correlation of donors and the magnetic field strength make the electron more binding

Revolutionary family life and the self respect movement in Tamil south India, 1926-49

During the second quarter of the 20th century, the Self Respect movement (cuyamariyatai iyakkam) introduced a programme of non-Brahmin uplift in Tarnil south India that consisted of a radical critique of social, political and economic relations. By following the coverage of family and marriage in the Self Respect popular press (the weekly newspaper Kudi Arasu in particular), and through interviews with Self Respecters who lived through the period 1926-49, this article attempts to sketch out how and why the family was interpolated both as an object of criticism and as a site of struggle. That is to say, Self Respect was not only a set of arguments, but also a set of practical strategies for transforming everyday and ritual life into revolutionary propaganda through choice of dress, names, home decor and domestic ritual, as well as through attending public meetings and reading newspapers. In particular, 'modern, Self Respecting Tamil couples' were projected as a resolution to what the Self Respect movement high-lighted as the social, political and economic problems perpetuated by the traditional joint family. Yet, over the course of the 20th century in the Tamil south, marriage and family proved to be unstable vehicles for the revolutionary transformation of socio-political domains
