News:
Two new papers in spring 2025: Finite-momentum excitons with our screened hybrid functional, PRB 111, 155202 (2025)Â (with Didar and Jiuyu) and our long awaited stability analysis of the time-dependent LRC approach, JCTC (2025) (with Jared).
Our paper "Spin waves with source-free time-dependent spin density functional theory" with Jenna Bologa was published today in PRB 110, 235121 (2024)
Jared Williams has defended his PhD in Fall 2024. The title of his thesis is "A study of time-dependent exciton dynamics: insights from 1- and 2-dimensional model systems". Congratulations, Jared!
Our collaboration with Deepak Singh's group has successfully led to a paper in Nature Communications, "Persistent dynamic magnetic state in artificial honeycomb spin ice" (August 2023). Daniel's simulations were a central part of this work.
