Dynamical processes endow materials and chemical systems with functionality. Understanding non-equilibrium phenomena, especially far from the ground state, is crucial for the rational design of functional materials and devices. The generation, conversion and storage of energy, information, and matter can only be controlled with a mechanistic understanding of excited state processes that go beyond final state outcomes. Additionally, addressing correlations across disparate length and time scales, the role of quantum coherence, the use of nonlinear couplings and bifurcation points, will enable progress in this area. This symposium will survey recent progress in manipulation, measurement, and simulation of non-equilibrium dynamics, spanning the time scales of ultrafast electronic motion and slower structural and chemical transformations.
This symposium is organized by the Center for Non-Perturbative Studies of Functional Materials under Non-Equilibrium Conditions, a DOE center for developing open-source software that will facilitate fundamental advances in materials science through a collaborative experimental and theoretical approach.
