Neutron diffraction (HB-1A, HB-2A, and HB-2C) and inelastic neutron scattering (SEQUOIA) data for Ce3TiBi5 and Ce3ZrBi5. See arXiv:2602.23316. For HB-2A and SEQUOIA, standard auto-reduced files are provided. For HB-1A and HB-2C, processed data files used for the figures in the manuscript are provided.
Inelastic neutron scattering data measured on ARCS, CNCS, and HYSPEC are provided here. The .nxs files contain complete datasets and the .txt/.dat files contain the data slices extracted from those datasets and used to generate the figures presented in the manuscript. The datasets have been reduced using MANTID and SHIVER.

This research project focuses on developing innovative materials that demonstrate unique quantum properties, specifically within electron systems that exhibit complex interactions, known as "correlated electron systems." Unlike non-correlated materials, finding topological phases (special states of matter with protected properties that make them stable against defects) in these correlated systems is a significant challenge. The project aims to design synthetic templates of two-dimensional "Kagome lattice" structures, made from specific materials called iridates and osmates, to study and control these exotic quantum behaviors. To achieve this, the project employs a cutting-edge spectroscopic tools that allow precise analysis of artificial quantum materials in terms of both energy and momentum while they are being created, using a specialized laser-based process called laser Molecular Beam Epitaxy.

The goal of this project is to build an ultrafast entangled photon spectrometer and use it to measure theoretical predictions that photoexcited states are enhanced by spin-photon interactions. Entanglement of two states describes a specific type of quantum superposition in which measuring one state gives information about a second state. While entanglement is well explored for quantum information and computing systems, its effects on photoexcited states are less understood, especially in the ultrafast domains of molecular vibronic coupling. The grant designs a frequency and temporally resolved entangled photon spectrometer and uses it to test theoretical predictions like enhanced two photon absorption, non-reciprocal Fourier relations, and coupling of photons to spin systems. The end goal of the project is an understanding of how, when, and where entanglement is useful for spectroscopy.
