In this work we implement the self-consistent Thomas-Fermi model that also incorporates a local conductivity model to an electron-electron bilayer system, in order to describe novel magneto-transport properties such as the Drag Phenomenon. The model can successfully account for the poor screening of the potential within the incompressible strips and its impact on the inter-layer Coulomb interaction. An externally applied current in the active layer results in the tilting of the Landau levels and built-up of a Hall potential across the layer, which, in turn, induces a tilted potential profile in the passive layer as well. We investigate the effect of the current intensity, temperature, magnetic field, and unequal density of layers on the self-consistent density and potential profiles of the bilayer system.

Labor-force participation of married women in Turkey: a study of the added-worker effect and the discouraged-worker effect Karaoglan, D.; Okten, C. (Routledge, 2015)We analyze married women's labor-supply responses to their husbands' job loss (added-worker effect) and worsening of unemployment conditions (discouraged-worker effect). We construct six two-year pseudopanels based on the ...
