Bingbing Wang is a PhD student at the School of Physics, Beijing Institute of Technology (BIT), Beijing, China. She obtained my Bachelor’s degree in Physics from BIT in 2023. Her research interest focuses on correlations and topology in condensed matter physics, particularly on widely studied Fractional Chern insulator (FCI) in moiré systems. She uses exact diagonalization (ED) to calculate many-body energy spectra, entanglement spectrum, and many-body Chern number to investigate the many-body states such as FCI and charge density wave (CDW) states. She and her collaborators studied pressure-tuned phase transitions in twisted bilayer MoTe2, and our paper is available on arXiv:2504.11177. She is also interested in the fractional quantum hall effect appearing in bands with quantum geometry beyond the Landau level mimicry.
