Query: Roton Induced Modulations in Underdoped Cuprates as a Signature of
  Incipient Electronic Order   In the last years there have been measurements of energy independent
modulations in underdoped cuprates via scanning tunelling microscopy. These
modulations of around 4 lattice constants occur near vortex cores in samples
with and without superconductivity, and in the pseudogap regime of some
superconducting samples. Recently, it was proposed that the origin of the
modulations is electronic charge ordered phases intrinsic to doped Mott
insulators. We show that even if the system has not charge ordered, proximity
to such an order will induce modulations at the same ordering wavevector. Such
modulations are a signature of the real or incipient order. We construct ground
state wavefunctions that include strong fluctuations of the competing order
without having ordered. They exhibit deep roton minima at wavevectors of the
reciprocal lattice of the incipient order due to proximity to the phase
transition into the charge ordered state. Such minima, in turn, produce strong
modulations. Moreover, the effects are generic and are present whenever an
electronic system is near a crystalline phase. This leads to experimental
signatures even if the electronic system has not solidified. The signatures
will be ubiquitous near the dopings that stabilize the electronic order.
