Olivier Delaire's research program investigates atomistic transport processes of energy and charge, and thermodynamics in energy materials (DOE Early Career Award 2014). His research group studies  elementary excitations in condensed-matter systems (phonons, electrons, spins), their couplings (phonon-phonon interaction, electron-phonon coupling, spin-phonon coupling), and their effects on macroscopic material properties. Current materials of interest include thermoelectrics, ferroelectrics/multiferroics, spin-caloritronics, and photovoltaics. We develop new methods to reveal microscopic underpinnings of thermal transport, by integrating neutron and x-ray scattering measurements with quantum-mechanical computer simulations. This combined experimental and computational approach opens a new window to understand and control microscopic energy transport for the design of materials with novel properties (thermoelectrics, spin-caloritronics), and to rationalize multiferroics and metal-insulator transitions. In addition to state-of-the-art scattering experiments and first-principles simulations, our team also uses transport measurements, optical spectroscopy, materials synthesis, calorimetry, and thermal characterization, with the goal of gaining deeper atomistic understanding for developing future materials.
