Charge and statistics of lattice quasiholes from density measurements: A tree tensor network study

We numerically investigate the properties of the quasihole excitations above the bosonic fractional Chern insulator state at filling ν=1/2, in the specific case of the Harper-Hofstadter Hamiltonian with hard-core interactions. For this purpose, we employ a tree tensor network technique, which allows...
