Query: Dynamically-enhanced strain in atomically thin resonators   Graphene and related two-dimensional (2D) materials associate remarkable
mechanical, electronic, optical and phononic properties. As such, 2D materials
are promising for hybrid systems that couple their elementary excitations
(excitons, phonons) to their macroscopic mechanical modes. These built-in
systems may yield enhanced strain-mediated coupling compared to bulkier
architectures, e.g., comprising a single quantum emitter coupled to a
nano-mechanical resonator. Here, using micro-Raman spectroscopy on pristine
monolayer graphene drums, we demonstrate that the macroscopic flexural
vibrations of graphene induce dynamical optical phonon softening. This
softening is an unambiguous fingerprint of dynamically-induced tensile strain
that reaches values up to $\mathbf{\approx 4 \times 10^{-4}}$ under strong
non-linear driving. Such non-linearly enhanced strain exceeds the values
predicted for harmonic vibrations with the same root mean square (RMS)
amplitude by more than one order of magnitude. Our work holds promise for
dynamical strain engineering and dynamical strain-mediated control of
light-matter interactions in 2D materials and related heterostructures.
