Sometimes, qToM’s research, in tutorial, presentation or seminar format, makes it to YouTube. Check out some of our audio-visual work below, or keep an eye on our YouTube and Twitter channels for more.


Trinity College Dublin PhD student Lórien MacEnulty embarks on an introduction to the PAW formalism in density functional theory (DFT), focusing on how it is implemented in DFT codes. MacEnulty talks about what is contained in a PAW dataset and how to derive a pseudopotential from said dataset. [6] This talk is followed by a short discussion on the manifestation of PAW in the LDA+U formalism. See original YouTube posting for full reference and figure listings.

Calculation of the magnetostatic dipole-dipole correction to periodic spin-density functional theory using an auxiliary magnetic charge density (link to paper). This research was conducted by L. MacEnulty and Prof. David O’Regan and presented by L. MacEnulty at the MRS Spring Meeting in April of 2021. This research was funded by Science Foundation Ireland through the Advanced Materials and Bioengineering Research Centre (AMBER, Grant No. 12/RC/2278).
