Condensed Matter Experiment

Overview

We study hard materials (for magnetic, optical, photonics, and sensor applications) as well as soft matter (to better understand ordering and dynamics of biological and colloidal systems).

Our interests span bulk materials, thin films and multilayers, and surfaces and interfaces. Techniques used span Brillouin, Raman and femtosecond laser spectroscopy, ultrasonic spectroscopy, wideline and pulse-field gradient nuclear magnetic resonance (NMR) spectroscopy and imaging, and scanning probe and laser-scanning confocal microscopies, in addition to electrodeposition, magnetometry, as well as several other materials characterization techniques available on campus.
