Query: Synthetic gauge field in a single optomechanical resonator   Synthetic gauge fields have recently emerged, arising in the context of
quantum simulations, topological matter, and the protected transportation of
excitations against defects. For example, an ultracold atom experiences a
light-induced effective magnetic field when tunnelling in an optical lattice,
and offering a platform to simulate the quantum Hall effect and topological
insulators. Similarly, the magnetic field associated with photon transport
between sites has been demonstrated in a coupled resonator array. Here, we
report the first experimental demonstration of a synthetic gauge field in the
virtual dimension of bosonic modes in a single optomechanical resonator. By
employing degenerate clockwise (CW) and counter-clockwise (CCW) optical modes
and a mechanical mode, a controllable synthetic gauge field is realized by
tuning the phase of the driving lasers. The non-reciprocal conversion between
the three modes is realized for different synthetic magnetic fluxes. As a
proof-of-principle demonstration, we also show the dynamics of the system under
a fast-varying synthetic gauge field. Our demonstration not only provides a
versatile and controllable platform for studying synthetic gauge fields in high
dimensions but also enables an exploration of ultra-fast gauge field tuning
with a large dynamic range, which is restricted for a magnetic field.
