Query: Switching valley filtered current directions in multi-terminal graphene
  systems   Valley filtering processes have been explored in different graphene-based
configurations and scenarios to control transport responses. Here we propose
graphene multi-terminal set-ups properly designed to obtain valley filtered
currents in a broad range of energy, besides the possibility of controlling
their directions. We explore graphene systems with extended mechanical
fold-like deformations as an opportunity to enhance valley filtered
transmission. The mixing between the electronic confinement effects due to a
magnetic field and strain results in a selective drive of the current
components in the quantum Hall regime. We adopt the mode-matching method within
the Green's function formalism, allowing the direct analysis of the strain
effect on each valley transmission. We estimate a threshold map of confinement
parameters, characterized by the magnetic, deformation, and set-up lengths, to
optimize valley filter transport processes and the proper switch of the valley
polarized current directions.
