ExSiTE Lab

Welcome to the ExSiTE Lab (Experiments and Simulations in Thermal Engineering) at UVA, and research homepage for Professor Patrick E. Hopkins. Our group’s interests are in energy transport and coupled photonic interactions with condensed matter, soft materials, liquids, vapors, plasmas and their interfaces.  We use various optical thermometry-based experiments to measure the thermal conductivity, thermal boundary conductance, thermal accommodation, strain propagation and sound speed, optical properties, and electron, phonon, vibrational and polaritonic scattering mechanisms in a wide array of bulk materials and nanosystems.

Group Member Publication: Congrats to Dr. Eric Hoglund for his first author publication in Nature, demonstrating evidence of unique vibrational modes in superlattices with STEM EELS that directly impact unique signatures in thermal conductivity and nonlinear optical properties.

Hoglund, E.R., et al., “Nanoscale phonon spectroscopy reveals emergent interface vibrational structure of superlattices,” Nature 601, 556-561 (2022). PDF (Supporting Information).
