Query: Creating, probing, and manipulating fractionally charged excitations of
  fractional Chern insulators in optical lattices   We propose a set of schemes to create and probe fractionally charged
excitations of a fractional Chern insulator state in an optical lattice. This
includes the creation of localized quasiparticles and quasiholes using both
static local defects and the dynamical local insertion of synthetic flux
quanta. Simulations of repulsively interacting bosons on a finite square
lattice with experimentally relevant open boundary conditions show that already
a four-particle system exhibits signatures of charge fractionalization in the
quantum-Hall-like state at the filling fraction of $1/2$ particle per flux
quantum. This result is favorable for the prospects of adiabatic preparation of
fractional Chern insulators. Our work is inspired by recent experimental
breakthroughs in atomic quantum gases: the realization of strong artificial
magnetic fields in optical lattices, the ability of single-site addressing in
quantum gas microscopes, and the preparation of low-entropy insulating states
by engineering an entropy-absorbing metallic reservoir.
