Qianhui Xu is currently a fourth-year doctoral student in Physics at NTU, Singapore. Her research aims to deepen the understanding of the fractional quantum Hall (FQH) fluid and, more broadly, the behaviour of two-dimensional electron gases, where strong electron–electron interactions play a pivotal role in the emergence of topological phases and corresponding experimental phenomena. Xu’s work includes examining the nontrivial dynamics of anyons—both in the Laughlin 1/3 state and the non-Abelian Moore–Read state—arising from electron interactions, along with investigating experimental methods that could probe these effects. She also explores quantum solid phases that compete with the FQH fluid, such as Wigner crystals and bubble phases in higher Landau levels.
