Wigner Cusp Anomalies in Multimode Systems

Live Poster Session: Zoom Link Abstract: Most sensors operate on a linear response principle (LRP) which implies a fundamental bound on the dynamic range of a sensor: the ratio between the maximum and minimum perturbations a sensor can measure. To overcome this limit a nonlinear sensing scheme is required. We have recently identified that such … Read more

Implementation of an augmented Tersoff potential to describe the phase-change material GeTe

Abstract: Our work revolves around building and utilizing molecular dynamics simulations to characterize the dynamics of phase-change materials. This summer has been focused on implementing an augmented Tersoff potential. Derived by Federico Zipoli and Alessandro Curioni, this potential will allow longer time-scale simulations of Germanium-Telluride with the open-source code LAMMPS. Topics we plan on exploring … Read more
