Jessica McChesney

Jessica McChesney is a physicist at the Advanced Photon Source, Argonne National Laboratory, whose research focuses on using x-ray techniques to study the electronic properties of quantum materials. She utilizes both resonant and non-resonant angle-resolved photoemission (ARPES) along with x-ray absorption spectroscopy (XAS) and resonant soft x-ray scattering (RSXS) to investigate the interplay between the spin, charge, orbital and lattice degrees of freedom. It is from this competition within these many body systems that exotic quantum ground states emerge. These quantum materials  include topological materials like Dirac semimetal and Weyl materials, complex oxides, and low-dimensional systems such as thin films and heterostructures, stacked van der Waals materials, self-assembled nanostructures and quantum well states, are relevant to quantum computing and sensing, nanoelectronics and energy storage needs.
