Comment on "Electron transport through correlated molecules computed using the time-independent Wigner function: Two critical tests"
The many electron correlated scattering (MECS) approach to quantum electronic
transport was investigated in the linear response regime [I. Baldea and H.
Koeppel, Phys. Rev. B. 78, 115315 (2008)]. The authors suggest, based on
numerical calculations, that the manner in which the method imposes boundary
conditions is unable to reproduce the well-known phenomena of conductance
quantization. We introduce an analytical model and demonstrate that conductance
quantization is correctly obtained using open system boundary conditions within
the MECS approach.Comment: 18 pages, 4 figures. Physical Review B, to appea

Formation and Equilibrium Properties of Living Polymer Brushes
Polydisperse brushes obtained by reversible radical chain polymerization
reaction onto a solid substrate with surface-attached initiators, are studied
by means of an off-lattice Monte Carlo algorithm of living polymers (LP).
Various properties of such brushes, like the average chain length and the
conformational orientation of the polymers, or the force exerted by the brush
on the opposite container wall, reveal power-law dependence on the relevant
parameters. The observed molecular weight distribution (MWD) of the grafted LP
decays much more slowly than the corresponding LP bulk system due to the
gradient of the monomer density within the dense pseudo-brush which favors
longer chains. Both MWD and the density profiles of grafted polymers and chain
ends are well fitted by effective power laws whereby the different exponents
turn out to be mutually self-consistent for a pseudo-brush in the
strong-stretching regime.Comment: 33 pages, 11 figues, J.Chem. Phys. accepted Oct. 199
