Geometry and kinetics determine the microstructure in arrested coalescence of Pickering emulsion droplets
Zhaoyu Xie, Christopher J. Burke, Badel Mbanga +2
An important strategy to stabilize emulsions is to arrest coalescence of the constituent droplets with an opposing rheological force. Colloidal particles adsorbed on the surface of…
Intradomain phase transitions in flexible block copolymers with self-aligning segments
Christopher J. Burke, Gregory M. Grason
We study a model of flexible block copolymers (BCPs) in which there is an enlthalpic preference for local alignment, among like-block segments. We describe a generalization of the…
Percolation transition in the packing of bidispersed particles on curved surfaces
Andrew M. Mascioli, Christopher J. Burke, Timothy J. Atherton
We study packings of bidispersed spherical particles on a spherical surface. The presence of curvature necessitates defects even for monodispersed particles; bidispersity either le…
Jamming on curved surfaces
Christopher J. Burke, Timothy J. Atherton
Colloidal and other granular media experience a transition to rigidity known as jamming if the fill fraction is increased beyond a critical value. The resulting jammed structures a…
Developing a project-based computational physics course grounded in expert practice
Christopher Burke, Timothy J Atherton
We describe a project-based computational physics course developed using a backwards course design approach. From an initial competency-based model of problem solving in computatio…
Maximizing the hyperpolarizability of 1D potentials with multiple electrons
Christopher J. Burke, Joseph Lesnefsky, Rolfe G. Petschek +1
We optimize the first and second intrinsic hyperpolarizabilities for a 1D piecewise linear potential dressed with Dirac delta functions for non-interacting electrons. The optim…
The role of curvature anisotropy in the ordering of spheres on an ellipsoid
Christopher J. Burke, Badel L. Mbanga, Zengyi Wei +2
Non-spherical emulsion droplets can be stabilized by densely packed colloidal particles adsorbed at their surface. In order to understand the microstructure of these surface packin…
Optimizing the second hyperpolarizability with minimally-parametrized potentials
Christopher J. Burke, Joseph Lesnefsky, Rolfe G. Petschek +1
The dimensionless zero-frequency intrinsic second hyperpolarizability γ_{int}=γ/4E_{10}^{-5}m^{-2}(e\hbar)^{4} was optimized for a single electron in a 1D well by adjusting the sha…
