Sheikh Rubaiat Ul Haque
Postdoctoral Scholar, Photon Science, SLAC
BioRubaiat received his undergraduate degree in Applied Physics from the University of Tokyo in 2017. He then moved to the University of California San Diego where he finished his PhD in Physics under Professor Richard Averitt in 2023. During his PhD, he discovered light-induced terahertz parametric amplification and photonic time crystal state in excitonic insulator candidate Ta2NiSe5. His discovery has been featured in multiple media outlets including UCSD Today, Max Planck Institute Newsletter, EurekAlert! and Phys.org. He has also demonstrated a novel extreme-efficient nonresonant nonlinear magnon generation mechanism in Mott insulating Heisenberg antiferromagnet Sr2IrO4.
Currently, Rubaiat is a postdoctoral scholar at Stanford University investigating terahertz field-induced ultrafast dynamics in van der Waals materials under Professors Tony Heinz and Aaron Lindenberg. At Stanford, he has discovered terahertz-driven transition to a hidden magnetic state in van der Waals (vdW) antiferromagnet MnPS3. He has recently extended his research to subdiffractive THz spectroscopy of 2D vdW materials. His research interests also broadly include Floquet engineering, ultrafast microscopy, and cavity control of quantum materials. In the long term, Rubaiat aims to continue investigating quantum materials that may provide promising platforms for light-driven emergent phenomena and programming light-matter interactions, serving as a bridge between next-generation photonics and materials science. -

Britt Hedman
Professor of Photon Science
BioBritt Hedman’s research program is focused on the development and applications of x-ray absorption and emission spectroscopies using synchrotron radiation, with a scientific emphasis primarily on study of the electronic and structural aspects of metal ion active sites in bioinorganic and biological systems. A common theme is to investigate how structure at molecular and macromolecular levels relates to function.
A major long-term focus has been the active site of the enzyme nitrogenase, and the various nitrogenase metal clusters, including elucidating the electronic and geometric structure of those that are formed and changed along their biosynthetic pathways. Other systems of systematic studies include iron-sulfur cluster containing enzymes, blue and multi-copper proteins, heme-copper oxidases, and iron-containing oxidases. Methods developments include x-ray absorption spectroscopy (edge and extended fine structure - or EXAFS), including the application of multiple-scattering analysis in EXAFS studies of metal clusters relevant to bioinorganic systems, the development of methodology for polarized single crystal x-ray absorption spectroscopy, and methodology and instrumentation development for soft- through hard-energy XAS.
Britt Hedman received her B.S and B.A. in Chemistry, M.Sc. in Inorganic Chemistry, and Ph.D. in Chemistry from the University of Umeå, Sweden. She was Assistant Professor (equivalent) in Inorganic Chemistry at the University of Umeå before coming to Stanford, initially as Senior Academic Scientific Staff, followed by appointed as Professor (Research) in 2002, and Professor of Photon Science in 2007. -
