Query: Optomechanical interactions in non-Hermitian photonic molecules   We study optomechanical interactions in non-Hermitian photonic molecules that
support two photonic states and one acoustic mode. The nonlinear steady-state
solutions and their linear stability landscapes are investigated as a function
of the system's parameters and excitation power levels. We also examine the
temporal evolution of the system and uncover different regimes of nonlinear
dynamics. Our analysis reveals several important results: (1) Parity-time
($\mathcal{PT}$) symmetry is not necessarily the optimum choice for maximum
optomechanical interaction. (2) Stable steady-state solutions are not always
reached under continuous wave (CW) optical excitations. (3) Accounting for gain
saturation effects can regulate the behavior of the otherwise unbounded
oscillation amplitudes. Our study provides a deeper insight into the interplay
between optical non-Hermiticity and optomechanical coupling and can thus pave
the way for new device applications.
