Excluded-Volume Effects in Tethered-Particle Experiments: Bead Size Matters
Darren E. Segall, Phillip C. Nelson, Rob Phillips
The tethered-particle method is a single-molecule technique that has been used to explore the dynamics of a variety of macromolecules of biological interest. We give a theoretical…
Expanding the Temporal Analysis in Single-Molecule Switching Experiments Through the Auto-Correlation Function: Mathematical Framework
Darren E. Segall
A method is presented that, when used in conjunction with single molecule experimental techniques, allows for the extraction of rates and mechanical properties of a biomolecule und…
Ab initio and finite-temperature molecular dynamics studies of lattice resistance in tantalum
D. E. Segall, Alejandro Strachan, Sohrab Ismail-Beigi +2
This manuscript explores the apparent discrepancy between experimental data and theoretical calculations of the lattice resistance of bcc tantalum. We present the first results for…
New ab initio approach for high pressure systems with application to a new high-pressure phase for boron: perturbative momentum-space potentials
D. E. Segall, T. A. Arias
Through the use of perturbation theory, in this work we develop a method which allows for a substantial reduction in the size of the plane-wave basis used in density-functional cal…
Accurate Calculations of the Peierls Stress in Small Periodic Cells
D. E. Segall, T. A. Arias, Alejandro Strachan +1
The Peierls stress for a [111]-screw dislocation in bcc Tantalum is calculated using an embedded atom potential. More importantly, a method is presented which allows accurate calcu…
Elasticity of nanometer-sized objects
D. E. Segall, Sohrab Ismail-Beigi, T. A. Arias
We initiate the development of a theory of the elasticity of nanoscale objects based upon new physical concepts which remain properly defined on the nanoscale. This theory provides…
