Cognitive Grammar: The State of the Art and Related Issues: An Interview with Ronald M. Langacker

Cognitive linguistics can offer an account not only of linguistic structure but also of a wide variety of social and cultural phenomena. The comprehensive account presented in this paper is crucially based and dependent on cognitive capacities that human understanders and producers of language possess quite independently of their ability to use language. By discussing the cognitive processes and the various linguistic, social and cultural issues they help us describe and explain, the author demonstrates that cognitive linguistics is far more than a theory of language; one can think of it as a theory of "meaning-making" in general in its innumerable linguistic, social and cultural facets

Josephson current in ballistic superconductor-graphene systems

We calculate the phase, the temperature and the junction length dependence of the supercurrent for ballistic graphene Josephson junctions. For low temperatures we find nonsinusoidal dependence of the supercurrent on the superconductor phase difference for both short and long junctions. The skewness, which characterizes the deviaton of the current-phase relation from a simple sinusoidal one, shows a linear dependence on the critical current for small currents. We discuss the similarities and differences with respect to the classical theory of Josephson junctions, where the weak link is formed by a diffusive or ballistic metal. The relation to other recent theoretical results on graphene Josephson junctions is pointed out and the possible experimental relevance of our work is considered as well

Transfer matrix approach for the Kerr and Faraday rotation in layered nanostructures

To study the optical rotation of the polarization of light incident on multilayer systems consisting of atomically thin conductors and dielectric multilayers we present a general method based on transfer matrices. The transfer matrix of the atomically thin conducting layer is obtained using the Maxwell equations. We derive expressions for the Kerr (Faraday) rotation angle and for the ellipticity of the reflected (transmitted) light as a function of the incident angle and polarization of the light. The method is demonstrated by calculating the Kerr (Faraday) angle for bilayer graphene in the quantum anomalous Hall state placed on the top of dielectric multilayers. The optical conductivity of the bilayer graphene is calculated in the framework of a four-band model.Comment: 10 pages, 6 figure
