Magnetic alignment of block copolymer microdomains by intrinsic chain anisotropy
Yekaterina Rokhlenko, Kai Zhang, Manesh Gopinadhan +6
We examine the role of intrinsic chain susceptibility anisotropy in magnetic field directed self-assembly of a block copolymer using \textit{in situ} X-ray scattering. Alignment of…
Protocol dependence of the jamming transition
T. Bertrand, R. P. Behringer, B. Chakraborty +2
We propose a theoretical framework for predicting the protocol dependence of the jamming transition for frictionless spherical particles that interact via purely repulsive contact…
Experiments demonstrate that the null space of the rigidity matrix determines grain motion during vibration-induced compaction
A. Hubard, C. S. O'Hern, M. D. Shattuck
Using a previously developed experimental method to reduce friction in mechanically stable packings of disks, we find that frictional packings form tree-like structures of geometri…
Onset and cessation of motion in hydrodynamically sheared granular beds
Abram H. Clark, Mark D. Shattuck, Nicholas T. Ouellette +1
We performed molecular dynamics simulations of granular beds driven by a model hydrodynamic shear flow to elucidate general grain-scale mechanisms that determine the onset and cess…
Asymmetric crystallization during cooling and heating in model glass-forming systems
Minglei Wang, Kai Zhang, Zhusong Li +4
We perform molecular dynamics (MD) simulations of the crystallization process in binary Lennard-Jones systems during heating and cooling to investigate atomic-scale crystallization…
