‘Richard Haglund’
Researcher Highlight: Aaron Hunsaker
Oct. 4, 2023—Aaron Hunsaker, a 5th year Ph.D. student in Professor Haglund’s Applied Optical Physics group. I came to Vanderbilt through the Fisk-Vanderbilt Bridge Program, where I received my master’s degree in physics before transitioning to the physics Ph.D. program at Vanderbilt. My master’s research involved fabricating and characterizing a ceramic scintillator of cesium hafnium chloride. That...
“Ultrafast X-ray imaging of the light-induced phase transition in VO2” published in Nature Physics, selected as Spotlight Publication
Jan. 30, 2023—Congratulations to Richard Haglund and Kent Hallman for their Nature Physics publication. This paper is the latest from a multi-year, multi-national (United States, Germany, Denmark, South Korea, France, United Kingdom) collaboration in which Vanderbilt’s part was the preparation and characterization (in conjunction with the Technical University-Berlin) of a challenging ultrathin holographic gold-vanadium dioxide “sandwich” on...
