Título: Driven flow with exclusion and transport in graphene-like structures

Apresentador: Sergio L A de Queiroz (IF/UFRJ)

Resumo: The totally asymmetric simple exclusion process (TASEP), a
well-known model in its strictly one-dimensional (chain) version, is
generalized to cylinder (nanotube) and ribbon (nanoribbon) geometries.
A mean-field theoretical description is given for very narrow
ribbons ("necklaces"), and nanotubes. For specific configurations of
bond transmissivity rates, and for a variety of boundary conditions,
theory predicts equivalent steady state behavior between (sublattices on)
these structures and chains. This is verified by numerical simulations,
to excellent accuracy, by evaluating steady-state currents. We
also numerically treat ribbons of general width. We suggest that
this model may be applicable to the description of electronic transport in
carbon nanotubes and nanoribbons, under specific circumstances.
