Mobilities: Small Systems

October 12, 2021
Author(s)
J Husband, S R. Leone
Motion of one species with respect to another is governed by their mutual interaction potential. Since ions are readily manipulated in electricfields, experimentalists since the end of the nineteenth century have been able to direct and watch the flow of

Modal Reconstruction of Aspheric Surfaces From Experimental Second Derivatives

October 12, 2021
Author(s)
Nadia Machkour-Deshayes, Byoung C. Kim, Robert S. Polvani, Ulf Griesmann
A method for the measurement of precise aspheric optical surfaces based on measurements of the second derivatives of the surface is evaluated. A compact phase-measuring interferometer is used to determine the second derivatives of a surface on a survey

Model for Dispersion Rheology

October 12, 2021
Author(s)
J Bicerano, Jack F. Douglas, D A. Brune
A general model of the viscosity of complex-shaped particle dispersions is developed based on an exact virial expansion about the low concentration limit and a mathematical analogy between the hydrodynamics of concentrated particle suspensions and the

Molecular Computers for Solving Computational Decision Problems

October 12, 2021
Author(s)
Z Amitay, R Kosloff, S R. Leone
State-selective coherent control tailored molecular wave packets is implemented for solving computational decision problems. The current study involves graphs composed of vertices and edges, and the computational task is to determine the connectivity of a

Molecular Modeling of the Thermal Decomposition of Polymers

October 12, 2021
Author(s)
S I. Stoliarov, H Zhang, P R. Westmoreland, R Lyon, Marc R. Nyden
Applications presented in this work demonstrate the potential for using quantum mechanics and molecular simulations to determine the mechanisms and rates of the thermal decomposition of polymers. The expectation is that these capabilities can be used to

Molecular Production in Two Component Atomic Fermi Gases

October 12, 2021
Author(s)
J Chwedenczuk, K Goral, T K hler, Paul S. Julienne
We provide a practical approach to the molecular production via linear downward sweeps of Feshbach resonances in degenerate Fermi gases containing incoherent mixtures of two atomic spin states. We show that the efficiency of the association of atoms is

Molecular-scale Structural and Functional Characterization of Sparsely Tethered Bilayer Membranes

October 12, 2021
Author(s)
Duncan McGillivray, Gintaras Valincius, David J. Vanderah, W Febo-Ayala, John T. Woodward IV, F Hienrich, John J. Kasianowicz, M Losche
Surface-tethered biomimetic bilayer membranes (tethered lipid bilayer membranes, tBLMs) have been formed on gold surfaces from phospholipids and a synthetic 1-thiahexa(ethy lene oxide) lipid, WC14. They have been characterized using electrochemical

Morphology Dependence of Ultrafast Emission From Metal-Dendrimer Nanocomposites

October 12, 2021
Author(s)
O Varnavski, T Goodson, F Groehn, Barry J. Bauer, Eric J. Amis
We report the results of ultra-fast fluorescence investigations from gold-dendrimer nanocomposites of different morphologies. Femtosecond depolarized emission has been detected and characterized for Polyamidoamine (PAMAM) G5-based gold colloids, which

Multi-Pole Representation of the Dielectric Matrix

October 12, 2021
Author(s)
J A. Soininen, J J. Rehr, Eric L. Shirley
A good approximation for the electron self-energy or the electron quasiparticle properties is needed for an accurate calculation of x-ray absorption spectra. The GW approximation (GWA) has been found to be relatively reliable in predicting the
