- Abstract: Bloch oscillations are exotic phenomena describing the periodic motion of a
wave packet subjected to the external force in a lattice, where the system
possessing single- or multipleparticles could exhibit distinct oscillation
behaviors. In particular, it has been pointed out that quantum statistics could
dramatically affected the Bloch oscillation even in the absence of particle
interactions, where the oscillation frequency of two pseudofermions with the
anyonic statistical angle being pi becomes half of that for two bosons.
However, these statisticdependent Bloch oscillations have never been observed
in experiments up to now. Here, we report the first experimental simulation of
anyonic Bloch oscillations using electric circuits. By mapping eigenstates of
two anyons to modes of designed circuit simulators, the Bloch oscillation of
two bosons and two pseudofermions are verified by measuring the voltage
dynamics. It is found that the oscillation period in the two-boson simulator is
almost twice of that in the two-pseudofermion simulator, which is consistent
with the theoretical prediction. Our proposal provides a flexible platform to
investigate and visualize many interesting phenomena related to particle
statistics, and could have potential applications in the field of the novelty
signal control.

In the noninteracting case, quantized Thouless pumps can only occur when a topological singularity is encircled adiabatically.
In the presence of interactions, such topological transport can even persist for exotic paths in which the system gets arbitrarily close to the noninteracting singularity.
