Anisotropic Thermalization in Far-from-Equilibrium Flows
Arnab Debnath, Timothy Breitzman, Kaushik Dayal
We present a deterministic discontinuous Galerkin (DG) finite-element solution of the Boltzmann equation, without moment-closure approximations, under a class of far-from-equilibri…
Two-Scale Analysis of the Electrostatics of Dielectric Crystals: Emergence of Polarization Density and Boundary Charges
Shoham Sen, Yang Wang, Timothy Breitzman +1
Ionic crystals, such as solid electrolytes and complex oxides, are central to modern technologies for energy storage, sensing, actuation, and other functional applications. An impo…
Nonlocal Electrostatics and Boundary Charges in Continuum Limits of Two-Dimensional Materials
Shoham Sen, Yang Wang, Timothy Breitzman +1
Two-dimensional (2D) electronic materials are of significant technological interest due to their exceptional properties and broad applicability in engineering. The transition from…
Dipolar Self-Interactions Drive Polymer Chain Collapse
Pratik Khandagale, Gal deBotton, Timothy Breitzman +2
We report that a dielectric polymer chain, constrained at both ends, sharply collapses when exposed to a high electric field. The chain collapse is driven by nonlocal dipolar inter…
