My name is Bingbing Wang, and I am a PhD candidate at the School of Physics, Beijing Institute of Technology (BIT), Beijing, China. I obtained my Bachelor’s degree in Physics from BIT in 2023. My research interest focuses on correlations and topology in condensed matter physics, particularly on widely studied fractional Chern insulator (FCI) in moiré systems. I use 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. I and my collaborators studied pressure-tuned phase transitions in twisted bilayer MoTe2, and our paper is available on arXiv:2504.11177. I am also interested in the fractional quantum hall effect appearing in bands with quantum geometry beyond the Landau level mimicry.
