Min Long is a third-year doctoral student in the Department of Physics at HKU. His research focuses on the spectral properties of model fractional Chern insulators (FCIs) and their implications for quantum phase transitions, employing techniques such as density matrix renormalisation group (DMRG) and the time-dependent variational principle (TDVP). In his FCI model, Long uncovered an FCI–charge density wave (CDW) transition induced by the softening of magneto-rotons, and identified the chiral graviton mode using phenomenological chiral quadrupolar operators. His broader interests include the fractionalisation of crystalline symmetry in topological phases, examining how discrete crystalline symmetries generate fractionalised responses to topological defects. In addition, Long has investigated superconductivity in twisted bilayer graphene, applying the random phase approximation (RPA) to analyse potential pairing mechanisms.
