Scientific Interests and Work

First-principle simulations of static and dynamic compression.

First-principle simulations may provide a theoretical basis for all the interpretation of experiments as well as being a generator for new ideas to push the boundaries of fundamental science forward, provided that the computations have a strong foothold in reality. Dr. Abraham Hmiel’s work at the ISP revolves around simulations of static and dynamic compression, aiming to enhance our knowledge of materials science by probing length and time scales that are difficult for experiments to access. Dr. Hmiel is interested in the role of temperature effects, deformation, and volume compression in nanoscale systems in addition to high-performance computing and algorithms for quantum chemistry and molecular dynamics.

Background

As a graduate student at SUNY Albany (the College of Nanoscale Science and Engineering), Dr. Hmiel’s dissertation revolved around modeling water chemisorption on the (110) titanium oxide surface under forward and reverse electrical bias with traditional GGA-DFT and self-consistent van der Waals DFT. This led to new structural, energetic, and electronic insight on how the first surface monolayer of water reacts to an applied field. He also performed ab-initio simulations of quantum confinement and surface chemistry on 1D semiconducting nanostructures, probing the effect of atomic structure on electronic structure for low-dimensional nanomaterials.
