Computational Analysis of Silicon Nanoelectromechanical Systems
Next, we extend the quasicontinuum (QC) approach for multiscale analysis of silicon nanostructures at finite temperature. Three models, namely the real space quasiharmonic (QHM) model, the local quasiharmonic (LQHM) model, and the reciprocal space quasiharmonic (QHMK) model are investigated. Within …

Generating and protecting high fidelity multi-particle entangled states with atom-photon interactions
… a discrete state coupled to a finite bandwidth quasicontinuum, in the intermediate regime, where the bandwidth of the quasicontinuum cannot be treated as infinite or zero. This problem has many applications, including understanding how to generate an excited Rydberg superatom W state by driving …

On the role of topology and micro-structure on the adhesion and fracture of soft materials
… soft materials, using an extended version of the Quasicontinuum (QC) method. Explicit representation of the polymer chains is retained in regions of high interest, in the vicinity of cracks for example. Away from the imperfections, the network structure is computationally homogenized and only a …

Constitutive modeling of Cu-Al-Ni shape memory alloys
… but retaining leading discreteness effects. The quasicontinuum model now models the interface at a continuum scale but incorporates lattice effects. The kinetic relation obtained from such a model explains the experimentally observed difference in the stress required for moving boundaries between …
