Welcome to Daniel Kaplan’s page

I am a condensed matter theorist, focusing on engineering interactions in materials for exotic phenomena such as electronic topology, superconductivity, magnetism and charge instabilities. I use a combination of numerical tools (massively parallel calculations), analytics (diagrammatic perturbation theory), strong physical-chemistry insight (symmetry, atomic orbitals) and state-of-the-art quantum chemistry tools (density functional theory) for predicting materials and their properties. I have a vast record of publications in light-matter interaction, including ultrafast dynamics. I have recently succeeded in using AI for materials predictions, with particular emphasis on interpretability – with newly predicted de novo superconductors. My work has appeared in journals such as Nature, Nature Nanotechnology, Nature Communications, Physical Review Letters, PNAS (among others). Recently, I predicted superconductivity in twisted transition-metal dichalcogenides, and a new anomalous nonlinear Hall effect in a topological antiferromagnet and light-driven phase transitions stable against temperatures. I have collaborated extensively with experimental groups, notably, W Gao (NTU Singapore), W Wu (Rutgers), A. Pasupathy (Columbia University), A Kogar (UCLA) and SW Cheong (Rutgers).
