Many important aspects of the dynamic thermo-mechanical response of materials occur at the mesoscale, i.e. a physical scale of interactions smaller than what can be adequately described by homogenous behaviors, yet larger than the scale of the atomic

X-ray diffraction is important for analyzing crystals and their structures. Since the simulated diffraction patterns are costly, surrogate models are developed to enable fast time-to-solution. However, surrogate models produce slightly different outp

From quantum chemistry simulations using density functional theory, we obtain the total electronic energy of an eight-atom sulfur chain as its end-to-end distance is extended until S-S bond rupture occurs. We find that a sulfur chain can be extended

The molecular basis for rubber elasticity is arguably the oldest and one of the most important questions in the field of polymer physics. The theoretical investigation of rubber elasticity began in earnest almost a century ago with the development of

Coherent diffraction imaging (CDI) is a rapidly developing form of imaging that offers the potential of wavelength-limited resolution without image-forming lenses. In CDI, the intensity of the diffraction pattern is measured directly by the detector,

We present single-shot images of a laser-driven shock wave interacting with micron-scale materials heterogeneities taken with an X-ray free electron laser. We observed an evolution from an elastic to plastic shock wave in uniaxially loaded LiF and PE

At small length scales, the fluctuations that are neglected in most continuum descriptions of fluids become important. In this work, we explore the emergence of the Navier-Stokes equations as the ensemble mean of these fluctuations, which are inheren
