Advanced scattering experiments on quantum materials
The eXn Group is a condensed matter physics research team consisting of two laboratories and researchers working in the University of Houston’s department of Physics and the Texas Center for Superconductivity. We conduct experiments mainly on strongly correlated electrons systems (SCES) and low-dimensional (low-D) materials. We deploy x-ray and neutron scattering tools at national user facilities around the world. At our campus facilities, we are developing ultrafast time-resolved scattering to probes the materials classes SCES and novel low-D systems.

Chamini Pathiraja is a fifth-year graduate student at eXn Lab in the Department of Physics, University of Houston. She obtained her B.Sc. in Physics major from the University of Sri Jayewardenepura, Sri Lanka, with a first–class Honor. Then, she served as a temporary lecturer at the University of Kelaniya for nearly one year before starting her PhD program. Her research is focused on the Spectroscopic study of the electronic structure of two–dimensional magnetic materials. Currently, she is working on determining the electronic structure of chromium trihalides CrX3 (X=Cl, Br, and I) using XAS and RIXS data that she had collected during multiple beamtime experiments.
Jayajeewana is a graduate student at the eXn lab. His research is basically focused on 2D van der Waals magnetic materials (especially Chromium trihalides, Vanadium Trihalides, and CrSBr) and investigation of their electronic and magnetic properties using various techniques such as UED and RIXS. In addition, he is working on 3D designs and simulations which are needed to make the UED setup in the lab. He did his undergraduate studies at the University of Colombo, Sri Lanka. He loves to play cricket in his free time and likes to watch cricket games.
Jonathan Tebo is a second-year Ph.D. student in the eXn group. Jonathan obtained his B.S. in Physics from the University of Texas at Austin in 2022. His primary research interests are in electron, x-ray, and neutron ultrafast diffraction studies of 2D materials. Outside of the lab, Jonathan enjoys studying scripture, spending time with his girlfriend and family, and swimming laps.
Julia Niwemuto is a PhD. student at eXn lab. Julia holds a B. Sc. in Physics from University of Rwanda, and a M. Sc. in Condensed Matter Physics from ICTP-EAIFR, Rwanda. She is interested in studying 2D materials by the use of different scattering techniques. Currently, Julia is working on using high resolution RIXS to investigate the electron-phonon coupling and ligand exciton in CrCl3.
Sumit Khadka is a Ph.D. student at eXn lab. Sumit obtained his BSc in Applied Physics from KathmanduUniversity, Nepal in 2016. He is currently involved in study of 2D materials by the use of different scattering techniques with a focus on TMD materials. Sumit is currently using X-Ray and neutron scattering techniques, Pair Distribution Function Analysis, and Ultrafast Electron Diffraction techniques. In his free time, Sumit is fond of travelling, photography, and soccer.
Uche is from Enugu state in Nigeria where he graduated from the University of Jos with a bachelor’s degree in physics and a master’s degree in physics from Auburn University. He joined the eXn group at the University of Houston in the summer of 2021. He is interested in characterizing the structural and magnetic properties of strained 2D materials using x and neutron scattering techniques. In his spare time, he enjoys playing soccer, playing video games, cooking, and spending time with his friends and family.
