Parallel athermal quasistatic deformation stepping of molecular systems
Maximilian Reihn, Franz Bamer, Benjamin Stamm
The athermal quasistatic deformation method provides an elegant solution to overcome the limitation of short time spans in molecular simulations. It provides overdamped conditions,…
Numerically optimized FROG results for the study of red-shifted spectra in multi-frequency Raman generation
Sakthi Priya Amirtharaj, Zujun Xu, Donna Strickland +7
When multifrequency Raman scattering is driven in the transient regime by two chirped pump pulses, the resulting anti-Stokes orders exhibit asymmetric spectral broadening toward lo…
Predicting temperature-dependent failure and transformation zones in 2D silica glass through quasistatic Gaussian Phase Packets
Miguel SpÃnola, Shashank Saxena, Franz Bamer +1
The athermal quasistatic (AQS) method is a powerful technique to study the mechanical behavior of disordered systems. However, its applicability is limited to temperatures near zer…
Geometrical fingerprints of shear transformation zones in network glasses
Franz Bamer, Zhao Wu, Somar Shekh Alshabab
Oxide glasses have the structure of disordered covalent networks that are accountable for their mechanical response. Identifying the topological phenomena of the elastic structural…
Stochastic evolution elasto-plastic modeling of a metallic glass
Bin Xu, Zhao Wu, Jiayin Lu +4
This paper develops a general data-driven approach to stochastic elastoplastic modelling that leverages atomistic simulation data directly rather than by fitting parameters. The ap…
