Quantum systems host spectacular nonequilibrium effects and unconventional transport phenomena, but many of these remain challenging to predict and consequently, technologically unexplored. My group’s research focuses on how quantum systems behave, particularly away from equilibrium, and how we can harness emergent effects in these systems. By creating predictive theoretical and computational approaches to study dynamics, decoherence and correlations in molecules and materials, our work enables technologies that are inherently more powerful than their classical counterparts, ranging from scalable quantum information processing to ultra-high efficiency optoelectronic and energy conversion systems. Capturing these phenomena poses unique computational and theoretical challenges. In fact, the simultaneous contributions of processes that occur on many time and length-scales has eluded state-of-the-art computational physics and model Hamiltonian approaches alike, necessitating a new lens. In this context, I will focus on our work on approaches to describe excited-states in quantum matter, including electron-electron and electron-phonon interactions beyond leading order, and predicting emergent states introduced by external drives. Our approach brings quantum chemistry, quantum optics and condensed matter together to create unexpected and useful properties, including surprisingly long coherence times and propagation lengths, as well as enabling new quantum probes of correlations. I will also discuss our methods in spatially-resolved non-equilibrium transport in quantum matter. By introducing GPU-accelerated large-scale transport frameworks that retain microscopic scattering, we are overcoming long-standing barriers in the field and taking transport in matter to exascale computing. Finally, I will share our vision for the future towards crossing the finite-extended system divide, and leveraging the power of both classical high-performance computing and quantum computation paradigms in predicting new phenomena.
