Quantum transport properties of pure and functioned infinite lead-connection region-lead systembased on the zigzag graphene nanoribbon (2-zGNR) have been investigated. In this work the effectof the doping functionalization on the quantum transport of the 2-zGNR has been computationallystudied. Also, the effect of the imposed gate voltages (-3.0, 0.0 and +3.0 V) and bias voltages 0.0 to2.0 V hav...

The electronic properties of junctions defined electrostatically on twisted bilayer graphene can be addressed theoretically using lattice models. Recent works have introduced minimal local orbital models to describe at the magic angle (MATBLG) with different degrees approximation and accounting for fragile topology. In present work we use a Green's function formalism obtain spectral transport M...

We consider a version of the inverse problem for simple radiative transport equation (RTE) with local data, where boundary sources and measurements are restricted to single subset $ E domain \Omega $. show that this can be solved globally if restriction X-ray transform lines through is invertible on In particular, strictly convex, we data whenever an open boundary. The proof relies isolation an...

We consider the local convergence properties of the class of augmented Lagrangian methods for solving nonlinear programming problems whose global convergence properties are analyzed by Conn et al. (1993a). In these methods, linear constraints are treated separately from more general constraints. These latter constraints are combined with the objective function in an augmented Lagrangian while t...
