First-principles upper bounds on dark matter-electron scattering rates from condensed matter sum rules
Bradford A. Barker, Jay Epstein, Luke James +5
A wide variety of condensed matter systems are used or proposed as detectors to search for dark matter-electron scattering. In general, the scattering rate depends on detailed know…
Engineering van der Waals heterostructures for dispersion-selective meV-scale quantum sensing
Elizabeth A. Peterson
Quantum sensing of meV-scale scattering and absorption of impinging particles with electrons in solid state detectors is a challenging technological advancement with the potential…
Irradiation-induced amplification of electric fields at oxide interfaces as revealed by correlative DPC-STEM and DFT
Elizabeth A. Peterson, Dongye Liu, Sean H. Mills +5
Heterointerfaces are ubiquitous in modern devices, found in technologies ranging from microelectronics to structural components for energy applications. Many of these emerging tech…
TritonDFT: Automating DFT with a Multi-Agent Framework
Zhengding Hu, Kuntal Talit, Zhen Wang +8
Density Functional Theory (DFT) is a cornerstone of materials science, yet executing DFT in practice requires coordinating a complex, multi-step workflow. Existing tools and LLM-ba…
Putative excitonic insulating state in narrow-gap semiconductor LaCdAs
Caitlin S. Kengle, Noah Schnitzer, Elizabeth A. Peterson +8
Excitonic insulators are electronically-driven phases of matter characterized by the spontaneous condensation of electron-hole pairs. Here we show that LaCdAs undergoes…
